Beyer C, Currin CB, Williams T, Stein DJ. Meta-analysis of the comparative efficacy of benzodiazepines and antidepressants for psychic versus somatic symptoms of generalized anxiety disorder. Compr Psychiatry 2024; 132:152479. [PMID: 38564872 DOI: 10.1016/j.comppsych.2024.152479] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/24/2023] [Revised: 03/19/2024] [Accepted: 03/23/2024] [Indexed: 04/04/2024] Open
Abstract
BACKGROUND Benzodiazepines and antidepressants are effective agents for the treatment of generalized anxiety disorder (GAD), with the HAM-A frequently used as a primary outcome measure. The GAD literature is inconsistent regarding which medications are more effective for somatic versus psychic symptoms of GAD, and treatment guidelines do not advocate for prescribing based on subtype. This meta-analysis aimed to determine whether benzodiazepines and antidepressants have a differential impact on the somatic versus psychic subscales of the HAM-A in GAD. METHODS An electronic search was undertaken for randomized controlled trials of either benzodiazepines or antidepressants for GAD that reported treatment response using the HAM-A subscales. Data were extracted by independent reviewers. A random effects assessment of weighted mean difference with 95% confidence intervals and subgroup difference was applied. All analysis was done on SPSS 26. An assessment of bias, and of quality of evidence was performed. RESULTS 24 randomized controlled trials met the inclusion criteria: 18 antidepressant trials, 5 benzodiazepine trials and 1 of both. 14 studies were assessed as having between some and high risk of bias, while 10 were assessed as having low risk of bias. Benzodiazepines (WMD of 1.81 [CI 1.03, 2.58]) were significantly more effective than antidepressants (WMD of 0.83 [CI 0.64, 1.02]) for reducing somatic symptoms of GAD (Chi2 = 5.81, p = 0.02), and were also more effective (WMD of 2.46 [CI 1.83, 3.09]) in reducing psychic symptoms than antidepressants (WMD of 1.83 [CI 1.55, 2.10]), although this comparison did not reach statistical significance (Chi2 = 3.31, p = 0.07). CONCLUSION The finding that benzodiazepines were significantly more effective than antidepressants for somatic symptoms needs to be weighed up against potential benefits of antidepressants over benzodiazepines. It may be useful for future treatment guidelines for GAD to explicitly consider symptom subtype.

Abstract
This systematic literature review aimed to assess the efficacy and tolerability of agomelatine versus approved medications for the treatment of generalized anxiety disorder (GAD) in adult patients. We selected randomized controlled trials on various medications used to treat GAD in adult patients. An existing systematic literature review (Kong et al., 2020) was used to identify relevant studies published before 2020. Outcomes of remission and discontinuation due to adverse events (AEs) were analyzed, following a random-effects network meta-analysis approach. Of 25 identified studies, 20 and 22 studies were included in the network meta-analysis for studying the remission and discontinuation (due to AEs) outcomes, respectively. A statistically significant difference in the remission rate was observed between agomelatine and pregabalin [odds ratio (OR), 2.22; 95% confidence interval (CI), 1.19-4.21]. For the other comparators, the results were nonsignificant; however, all the point estimates were in favor of agomelatine. Similarly, for discontinuation because of AEs, the point estimates leaned consistently toward agomelatine suggesting its higher tolerability. The probabilities of agomelatine having the highest remission rate and lowest discontinuation (due to AEs) rate were 67% and 68%, respectively. Based on its demonstrated effectiveness and tolerability, agomelatine can be considered as a drug of choice for the treatment of GAD.

Abstract
AIMS Quetiapine is widely used to treat psychiatric disorders such as major depression, generalized anxiety disorder, dysthymic disorder, and insomnia other than schizophrenia and bipolar disorder. This study investigated the diagnostic distribution of quetiapine use in patients in a psychiatric hospital, the doses of quetiapine prescribed, and the plasma concentrations (Cps) of quetiapine and active metabolites. METHODS We enrolled 107 patients who had been prescribed quetiapine for at least 4 weeks. Diagnoses, demographics, and concomitant medications were recorded. Blood sampling was performed in the morning, approximately 12 h after the before-bed dose of quetiapine. RESULTS Diagnoses comprised schizophrenia (n = 25), bipolar disorder (n = 51), major depression (n = 15), dysthymic disorder (n = 9), and others (n = 7). The daily dose (DD) of quetiapine ranged from 25 to 800 (175.9 ± 184.4) mg, with the mean Cp being 105.6 ± 215.3 ng/ml, with a mean Cps/DD ratio of 0.58 ± 0.55 ng/ml/mg. There was a moderate positive linear correlation between the dose and Cps of quetiapine (r = 0.60), and the interpatient variation in Cps/DD ratio was up to 26-fold. CONCLUSION Quetiapine is used in various doses to treat many psychiatric disorders other than psychosis, and it is usually prescribed as a secondary antipsychotic for symptoms such as insomnia or agitation. A wide interpatient variation of the Cps/DD ratio was noticed. Patients of East Asian descent may exhibit a 50% to 100% increase in the Cps/DD ratio for quetiapine compared with patients of Western descent.

Abstract
Quetiapine is a common off-label antipsychotic drug for treating insomnia. Its effects in different disease conditions and dosages remain unclear. We conducted a systematic review and meta-analysis in clinical trials examining the efficacy of low-dose quetiapine in sleep. We obtained 21 clinical trials. Mean difference (MD), standard mean difference (SMD), and odds ratio (OR) were used to estimate the effect sizes using a random-effects model. The pooled results showed that quetiapine improved sleep quality compared with placebo (SMD: -0.57 [95%CI: -0.75, -0.4]). The SMD of sleep quality was correlated with age (coefficient: -0.0174) and sex (coefficient: -0.012). The significant effects were observed in the general anxiety disorder (SMD: -0.59 [95%CI: -0.92, -0.27]), major depressive disorder (SMD: -0.47 [95%CI: -0.66, -0.28]), and healthy (SMD: -1.33, [95%CI [-2.12, -0.54]) subgroups, at the dosage of 50 mg (SMD: -0.36 [95%CI: -0.36, -0.11]), 150 mg (SMD: -0.4 [95%CI: -0.52, -0.29]), and 300 mg (SMD: -0.17 [95%CI: -0.31,-0.04]). Quetiapine increased total sleep time compared with placebo (MD: 47.91 [95%CI: 28.06, 67.76]) but not when compared with other psychiatric drugs (MD: -4.19 [95%CI: -19.43, 11.05]). Adverse events (AEs) and discontinuation due to AEs were common among the quetiapine users. Quetiapine is effective as a sleep-helping drug. Precaution is suggested when interpreting the results on the elderly due to the high heterogeneity caused by incorporating patients over 66 years in the meta-analyses. We recommend an initial dosage of 50-150 mg/day with priority consideration for the elderly with GAD or MDD while monitoring its potential AEs.

[PMID: 36111795 DOI: 10.1002/med.21923] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2021] [Revised: 07/29/2022] [Accepted: 08/09/2022] [Indexed: 02/04/2023]
Abstract
Dopamine is a biologically active amine synthesized in the central and peripheral nervous system. This biogenic monoamine acts by activating five types of dopamine receptors (D1-5 Rs), which belong to the G protein-coupled receptor family. Antagonists and partial agonists of D2 Rs are used to treat schizophrenia, Parkinson's disease, depression, and anxiety. The typical pharmacophore with high D2 R affinity comprises four main areas, namely aromatic moiety, cyclic amine, central linker and aromatic/heteroaromatic lipophilic fragment. From the literature reviewed herein, we can conclude that 4-(2,3-dichlorophenyl), 4-(2-methoxyphenyl)-, 4-(benzo[b]thiophen-4-yl)-1-substituted piperazine, and 4-(6-fluorobenzo[d]isoxazol-3-yl)piperidine moieties are critical for high D2 R affinity. Four to six atoms chains are optimal for D2 R affinity with 4-butoxyl as the most pronounced one. The bicyclic aromatic/heteroaromatic systems are most frequently occurring as lipophilic appendages to retain high D2 R affinity. In this review, we provide a thorough overview of the therapeutic potential of D2 R modulators in the treatment of the aforementioned disorders. In addition, this review summarizes current knowledge about these diseases, with a focus on the dopaminergic pathway underlying these pathologies. Major attention is paid to the structure, function, and pharmacology of novel D2 R ligands, which have been developed in the last decade (2010-2021), and belong to the 1,4-disubstituted aromatic cyclic amine group. Due to the abundance of data, allosteric D2 R ligands and D2 R modulators from patents are not discussed in this review.

Metabolic adverse effects of off-label use of second-generation antipsychotics in the adult population: a systematic review and meta-analysis. Neuropsychopharmacology 2022; 47:664-672. [PMID: 34446830 PMCID: PMC8782876 DOI: 10.1038/s41386-021-01163-7] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/05/2021] [Revised: 07/14/2021] [Accepted: 08/08/2021] [Indexed: 02/07/2023]
Abstract
Prescription rates of second-generation antipsychotics (SGAs) are rapidly increasing for non-indicated (i.e., off-label) usage. SGAs used for approved indications are associated with significant metabolic adverse effects, including weight gain. The objective of this systematic review and meta-analysis is to evaluate the metabolic adverse effects of SGA use for off-label management of psychiatric illnesses in the adult population. We performed a systematic database search to identify randomized controlled trials (RCTs) that reported on weight and other metabolic outcomes with off-label use of SGAs among adults. Thirty-eight RCTs met inclusion criteria for this review; 35 of these studies, with a total of 4930 patients, were included in the quantitative meta-analysis. Patients treated with olanzapine, risperidone, and quetiapine were more likely to report weight gain as a side effect and experience clinically significant (≥7%) weight gain compared to those treated with a placebo. Among studies that reported weight as a continuous outcome, olanzapine was associated with significantly greater weight gain across all disorders (mean difference (MD) = 3.24 kg, 95% CI: 2.57-3.90 p = 0.001, N = 12 studies). Similar trends were noted with quetiapine and risperidone. A meta-regression analysis revealed a positive dose-response association between olanzapine dose and weight gain (regression coefficient: 0.36, p = 0.001). This review demonstrates that off-label use of SGAs, and particularly olanzapine, is associated with significant weight gain among adult patients. Our findings are concerning given the widespread off-label use of SGAs. Further studies are required to better understand the effects of off-label SGA use on other metabolic parameters. The study was registered with the PROSPERO international database of prospectively registered systematic reviews (PROSPERO #143186).

Abstract
Studies on psychotropic medications decrease, discontinuation, or switch have uncovered withdrawal syndromes. The present overview aimed at analyzing the literature to illustrate withdrawal after decrease, discontinuation, or switch of psychotropic medications based on the drug class (i.e., benzodiazepines, nonbenzodiazepine benzodiazepine receptor agonists, antidepressants, ketamine, antipsychotics, lithium, mood stabilizers) according to the diagnostic criteria of Chouinard and Chouinard [Psychother Psychosom. 2015;84(2):63-71], which encompass new withdrawal symptoms, rebound symptoms, and persistent post-withdrawal disorders. All these drugs may induce withdrawal syndromes and rebound upon discontinuation, even with slow tapering. However, only selective serotonin reuptake inhibitors, serotonin noradrenaline reuptake inhibitors, and antipsychotics were consistently also associated with persistent post-withdrawal disorders and potential high severity of symptoms, including alterations of clinical course, whereas the distress associated with benzodiazepines discontinuation appears to be short-lived. As a result, the common belief that benzodiazepines should be substituted by medications that cause less dependence such as antidepressants and antipsychotics runs counter the available literature. Ketamine, and probably its derivatives, may be classified as at high risk for dependence and addiction. Because of the lag phase that has taken place between the introduction of a drug into the market and the description of withdrawal symptoms, caution is needed with the use of newer antidepressants and antipsychotics. Within medication classes, alprazolam, lorazepam, triazolam, paroxetine, venlafaxine, fluphenazine, perphenazine, clozapine, and quetiapine are more likely to induce withdrawal. The likelihood of withdrawal manifestations that may be severe and persistent should thus be taken into account in clinical practice and also in children and adolescents.

Abstract
Generalized anxiety disorder (GAD) is characterized by persistent and excessive worry. Around half of the patients treated for GAD will fail to respond to initial treatment. Treatment-resistant (or refractory) GAD is defined as failure to respond to at least 1 trial of antidepressant therapy at adequate dose and duration. Review of the literature indicates several potential medication classes and individual agents that can be used as augmentation strategies to treat residual symptoms when recommended therapy per clinical practice guidelines fails. A thorough literature search revealed 2 medication classes with the largest amount of data to support their use in treatment-resistant GAD treatment: gamma-aminobutyric acid–related agents and atypical antipsychotics. This article focuses on evidence-based recommendations for the use of these agents as adjunctive therapies for patients with treatment-resistant GAD. Different pharmacologic approaches to use these agents are demonstrated through 2 patient cases in which patients have failed first-line treatment options.

Abstract
Background: Generalized anxiety disorder (GAD) is one of the most common psychiatric disorders associated with substantial dysfunction and socioeconomic burden. Pharmacotherapy is the first choice for GAD. Remission [Hamilton Anxiety Scale (HAM-A) score ≤7] is regarded as a crucial treatment goal for patients with GAD. There is no up-to-date evidence to compare remission rate and tolerability of all available drugs by using network meta-analysis. Therefore, the goal of our study is to update evidence and determine the best advantageous drugs for GAD in remission rate and tolerability profiles. Method: We performed a systematic review and network meta-analysis of double-blind randomized controlled trials (RCTs). We searched PubMed, EMBASE, Cochrane Central Register of Controlled Trials, Chinese National Knowledge Infrastructure, wanfang data, China Biology Medicine and ClinicalTrials.gov from their inception to March 2020 to identify eligible double-blind, RCTs reporting the outcome of remission in adult patients who received any pharmacological treatment for GAD. Two reviewers independently assessed quality of included studies utilizing the Cochrane Collaboration’s risk of bias tool as described in Cochrane Collaboration Handbook and extracted data from all manuscripts. Our outcomes were remission rate (proportion of participants with a final score of seven or less on HAM-A) and tolerability (treatments discontinuations due to adverse events). We calculated summary odds ratios (ORs) and 95% confidence intervals (CIs) of each outcome via pairwise and network meta-analysis with random effects. Results: Overall, 30 studies were included, comprising 32 double-blind RCTs, involving 13,338 participants diagnosed as GAD by DSM-IV criteria. Twenty-eight trials were rated as moderate risk of bias, four trials as low. For remission rate, agomelatine (OR 2.70, 95% CI 1.74–4.19), duloxetine (OR 1.88, 95% CI 1.47–2.40), escitalopram (OR 2.03, 95% CI 1.48–2.78), paroxetine (OR 1.74, 95% CI 1.25–2.42), quetiapine (OR 1.88, 95% CI 1.39–2.55), and venlafaxine (OR 2.28, 95% CI 1.69–3.07) were superior to placebo. For tolerability, sertraline, agomelatine, vortioxetine, and pregabalin were found to be comparable to placebo. However, the others were worse than placebo in terms of tolerability, with ORs ranging between 1.86 (95% CI 1.25–2.75) for tiagabine and 5.98 (95% CI 2.41–14.87) for lorazepam. In head-to-head comparisons, agomelatine, duloxetine, escitalopram, quetiapine, and venlafaxine were more efficacious than tiagabine in terms of remission rate, ORs from 1.66 (95% CI 1.04–2.65) for duloxetine to 2.38 (95% CI 1.32–4.31) for agomelatine. We also found that agomelatine (OR 2.08, 95% CI 1.15–3.75) and venlafaxine (OR 1.76, 95% CI 1.08–2.86) were superior to vortioxetine. Lorazepam and quetiapine were poorly tolerated when compared with other drugs. Conclusions: Of these interventions, only agomelatine manifested better remission with relatively good tolerability but these results were limited by small sample sizes. Duloxetine, escitalopram, venlafaxine, paroxetine, and quetiapine showed better remission but were poorly tolerated.

The identification, assessment and management of difficult-to-treat depression: An international consensus statement. J Affect Disord 2020; 267:264-282. [PMID: 32217227 DOI: 10.1016/j.jad.2020.02.023] [Citation(s) in RCA: 135] [Impact Index Per Article: 33.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/26/2019] [Revised: 01/07/2020] [Accepted: 02/06/2020] [Indexed: 12/26/2022]
Abstract
BACKGROUND Many depressed patients are not able to achieve or sustain symptom remission despite serial treatment trials - often termed "treatment resistant depression". A broader, perhaps more empathic concept of "difficult-to-treat depression" (DTD) was considered. METHODS A consensus group discussed the definition, clinical recognition, assessment and management implications of the DTD heuristic. RESULTS The group proposed that DTD be defined as "depression that continues to cause significant burden despite usual treatment efforts". All depression management should include a thorough initial assessment. When DTD is recognized, a regular reassessment that employs a multi-dimensional framework to identify addressable barriers to successful treatment (including patient-, illness- and treatment-related factors) is advised, along with specific recommendations for addressing these factors. The emphasis of treatment, in the first instance, shifts from a goal of remission to optimal symptom control, daily psychosocial functional and quality of life, based on a patient-centred approach with shared decision-making to enhance the timely consideration of all treatment options (including pharmacotherapy, psychotherapy, neurostimulation, etc.) to optimize outcomes when sustained remission is elusive. LIMITATIONS The recommended definition and management of DTD is based largely on expert consensus. While DTD would seem to have clinical utility, its specificity and objectivity may be insufficient to define clinical populations for regulatory trial purposes, though DTD could define populations for service provision or phase 4 trials. CONCLUSIONS DTD provides a clinically useful conceptualization that implies a search for and remediation of specific patient-, illness- and treatment obstacles to optimizing outcomes of relevance to patients.

Abstract
Anxiety disorders, including panic disorder/agoraphobia (PDA), generalized anxiety disorder (GAD), social anxiety disorder (SAD), and others, are the most prevalent mental disorders. In this paper, recommendations are given for the psychopharmacological treatment of these disorders which are based on comprehensive treatment guidelines, meta-analyses, and systematic reviews of available randomized controlled studies. Anxiety disorders can effectively be treated with psychotherapy, pharmacotherapy, or a combination of both. First-line drugs are the selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs). Benzodiazepines are not recommended for routine use due to their possible addiction potential. Other treatment options include the calcium modulator pregabalin, tricyclic antidepressants, buspirone, moclobemide, and others. Drug treatment can be combined with psychological treatments. Novel treatment strategies include medications that act on GABA, glutamate, and other neurotransmitter systems. After remission, medications should be continued for 6 to 12 months.

Abstract
OBJECTIVE Treatment for panic disorder (PD) have evolved, although there is still a strong unmet need for more effective and tolerable options. The present study summarizes and discusses recent evidence regarding the pharmacological and neuromodulatory treatment of PD. METHODS MEDLINE, Cochrane Library, PsycINFO and Thomson Reuters's Web of Science were searched for clinical trials published between 2010 and 2018. We included all prospective experimental studies including randomized controlled trials (RCT) and other clinical trials with more than 10 patients. RESULTS Only 11 articles met the inclusion criteria, including 4 RCT, 3 open clinical trials and 5 comparative clinical trials. RCT demonstrated efficacy of transcranial magnetic stimulation (TMS) in only one of two trials. Neither pindolol nor d-fenfluramine were effective in blocking flumazenil-induced panic attacks. Augmentation with quetiapine was not superior to placebo. Open trials indicated that escitalopram, vortioxetine and TMS may be effective. Comparative trials did not demonstrate superiority from any drug, but confirmed tranylcypromine, paroxetine, clonazepam and alprazolam as effective options. CONCLUSION The current study confirmed the efficacy of tranylcypromine, paroxetine, clonazepam, alprazolam and escitalopram. Vortioxetine and TMS, with duration of 4 or more weeks, also seems to be effective. Quetiapine, pindolol and d-fenfluramine were not considered effective compounds.

Abstract
The current study aimed to rationally develop and characterize pH-sensitive controlled release hydrogels by graft polymerization of gelatin (Gel) and hydroxypropyl methyl cellulose (HPMC) in the presence of glutaraldehyde (GA) using quetiapine fumarate for the treatment of schizophrenia. The prepared hydrogels discs were subjected to various physicochemical studies including: swelling, diffusion, porosity, sol-gel analysis, Fourier transform infrared spectroscopy, differential scanning calorimetry, and scanning electron microscopy. Three different pH values (1.2, 6.8 and 7.4) were used to determine shape, transition, and controlled release behavior of prepared hydrogels. Various kinetic models including zero order, first order, Higuchi model and Power Law equation were applied on drug release data. The optimized hydrogels were subjected to in vivo studies using albino rabbits. Swelling and release results were found to be insignificant (p < .05) evidencing that there was no significant difference in swelling and drug release rate of hydrogels in different pH mediums. Swelling, porosity, gel-fraction, and drug released (%) were found to be dependent on concentrations of Gel, HPMC, and GA. Kinetic models revealed that QTP-F release followed non-Fickian diffusion. In-vivo studies contributed significantly higher plasma QTP-F concentration (Cmax), time for maximum plasma concentration (Tmax), area under the curve (AUC0-inf) and half-life (t1/2) as 18.32 ± 0.50 µg/ml, 8.00 ± 0.01 hrs, 6021.2 ± 5.09 µg.hrs/ml and 10.06 ± 0.43 hrs, respectively, for test-hydrogels when compared to reference market brand (Qusel® 200 mg, Hilton Pharma, Karachi, Pakistan) QTP-F tablets. It might be concluded that QTP-F loaded pH-sensitive hydrogels were developed successfully with reduced dosing frequency for schizophrenia.

Abstract
INTRODUCTION Generalized anxiety disorder (GAD) is a common form of anxiety disorder. Selective serotonin reuptake inhibitors (SSRIs), serotonin and norepinephrine reuptake inhibitors (SNRIs), and benzodiazepines (BZs) are the most commonly prescribed medications for GAD, but little is known about the relative efficacy of these pharmacological treatments. Areas covered: This study provides a meta-analytic review of the efficacy of these medications in the treatment of adults with GAD. A comprehensive literature search yielded 54 articles reporting 56 unique studies with 12,655 participants treated with either pill placebo (6,191 participants), SSRIs (16 trials, 2,712 participants), SNRIs (17 trials, 2,603 participants), or BZs (23 trials, 1,149 participants). The overall combined effect size was modest to moderate (Hedges' g = 0.37, p < 0.0001). Effect sizes decreased significantly over time. SSRIs (Hedges' g = 0.33) and SNRIs (Hedges' g = 0.36) demonstrated significantly lower effect sizes than BZs (Hedges' g = 0.50). These findings were not due to differences in treatment length or publication year. Expert opinion: The results of this study suggest that the most common forms of pharmacotherapy for adult GAD are moderately effective, with BZs being the most effective drug.

Abstract
The first-line treatment for psychotic disorders remains antipsychotic drugs with receptor antagonist properties at D2-like dopamine receptors. However, long-term administration of antipsychotics can upregulate D2 receptors and produce receptor supersensitivity manifested by behavioral supersensitivity to dopamine stimulation in animals, and movement disorders and supersensitivity psychosis (SP) in patients. Antipsychotic-induced SP was first described as the emergence of psychotic symptoms with tardive dyskinesia (TD) and a fall in prolactin levels following drug discontinuation. In the era of first-generation antipsychotics, 4 clinical features characterized drug-induced SP: rapid relapse after drug discontinuation/dose reduction/switch of antipsychotics, tolerance to previously observed therapeutic effects, co-occurring TD, and psychotic exacerbation by life stressors. We review 3 recent studies on the prevalence rates of SP, and the link to treatment resistance and psychotic relapse in the era of second-generation antipsychotics (risperidone, paliperidone, perospirone, and long-acting injectable risperidone, olanzapine, quetiapine, and aripiprazole). These studies show that the prevalence rates of SP remain high in schizophrenia (30%) and higher (70%) in treatment-resistant schizophrenia. We then present neurobehavioral findings on antipsychotic-induced supersensitivity to dopamine from animal studies. Next, we propose criteria for SP, which describe psychotic symptoms and co-occurring movement disorders more precisely. Detection of mild/borderline drug-induced movement disorders permits early recognition of overblockade of D2 receptors, responsible for SP and TD. Finally, we describe 3 antipsychotic withdrawal syndromes, similar to those seen with other CNS drugs, and we propose approaches to treat, potentially prevent, or temporarily manage SP.

Abstract
Anxiety disorders (generalized anxiety disorder, panic disorder/agoraphobia, social anxiety disorder, and others) are the most prevalent psychiatric disorders, and are associated with a high burden of illness. Anxiety disorders are often underrecognized and undertreated in primary care. Treatment is indicated when a patient shows marked distress or suffers from complications resulting from the disorder. The treatment recommendations given in this article are based on guidelines, meta-analyses, and systematic reviews of randomized controlled studies. Anxiety disorders should be treated with psychological therapy, pharmacotherapy, or a combination of both. Cognitive behavioral therapy can be regarded as the psychotherapy with the highest level of evidence. First-line drugs are the selective serotonin reuptake inhibitors and serotonin-norepinephrine reuptake inhibitors. Benzodiazepines are not recommended for routine use. Other treatment options include pregabalin, tricyclic antidepressants, buspirone, moclobemide, and others. After remission, medications should be continued for 6 to 12 months. When developing a treatment plan, efficacy, adverse effects, interactions, costs, and the preference of the patient should be considered.

Abstract
Quetiapine is an atypical antipsychotic drug that is widely used for the treatment of schizophrenia. It is mainly metabolized by a cytochrome P450 system in the liver. Norquetiapine is a major active metabolite in humans with a pharmacological profile that differs distinctly from that of quetiapine. We used the whole-cell patch-clamp technique to investigate the effects of norquetiapine on hERG channels that are stably expressed in HEK cells. Quetiapine and norquetiapine inhibited the hERG tail currents at -50mV in a concentration-dependent manner with IC50 values of 8.3 and 10.8μM, respectively, which suggested equal potency. The block of hERG currents by norquetiapine was voltage-dependent with a steep increase over a range of voltages for channel activation. However, at more depolarized potentials where the channels were fully activated, the block by norquetiapine was voltage-independent. The steady-state inactivation curve of the hERG currents was shifted to the hyperpolarizing direction in the presence of norquetiapine. Norquetiapine did not produce a use-dependent block. A fast application of norquetiapine inhibited the hERG current elicited by a 5s depolarizing pulse to +60mV, which fully inactivated the hERG currents, suggesting an inactivated-state block. During a repolarizing pulse wherein the hERG current was slowly deactivated, albeit remaining in an open state, a fast application of norquetiapine rapidly and reversibly inhibited the open state of the hERG current. Our results indicated that quetiapine and norquetiapine had equal potency in inhibiting hERG tail currents. Norquetiapine inhibited the hERG current by preferentially interacting with the open and/or inactivated states of the channels.

Abstract
PURPOSE OF REVIEW The purpose of this review was to assess and present the findings up to this date on the efficacy of antipsychotics in the treatment of generalized anxiety disorders (GAD), social anxiety disorders (SAD), panic disorders (PD), and obsessive-compulsive disorders (OCD), mostly based on published randomized controlled trials (RCTs) or on open-label studies when RCT were lacking. RECENT FINDINGS Quetiapine could be recommended in patients with GAD. The efficacy of aripiprazole in two open-label studies on patients with antidepressant-refractory GAD should be assessed in RCTs. Despite preliminary positive results in open studies, there are currently no strong evidence for the effectiveness of antipsychotics in refractory SAD and in refractory PD. Conversely, risperidone and aripiprazole can be used for the treatment of refractory OCD as augmentation agents to antidepressants. Contrary to SAD and PD, this review found evidence for the use of second-generation antipsychotics in GAD and OCD. Otherwise, first-generation antipsychotics cannot be recommended in anxiety disorders and OCD.

Abstract
OBJECTIVE This study aims to compare treatment response in bipolar I or II depression and generalized anxiety disorder (GAD) with and without recent alcohol and/or cannabis use disorder (ALC/CAN) to quetiapine-XR (extended release) or placebo. METHODS A randomized, double-blind, 8-week study of quetiapine-XR versus placebo in patients with bipolar I or II depression and GAD with or without a recent ALC/CAN was used to compare changes in Hamilton Depression Rating Scale-17, Hamilton Anxiety Rating Scale, the 16-item Quick Inventory of Depressive Symptomatology-Self-Report (QIDS-SR-16), Clinical Global Impression for Bipolar Disorder-Severity (CGI-BP-S), and Timeline Follow Back within and between groups. RESULTS In the quetiapine-XR group, patients with a recent ALC/CAN (n = 22) had significant decreases in QIDS-SR-16 (-9.6 ± 1.6 vs. -3.7 ± 1.7) and CGI-BP-S (-1.6 ± 0.4 vs. -0.8 ± 0.03) than those without a recent ALC/CAN (n = 24). In the placebo group, both patients with a recent ALC/CAN (n = 23) and those without (n = 21) had similar reductions in these measures. The reduction of QIDS-SR-16 scores in patients with a recent ALC/CAN was also significantly different from that of their counterparts in the placebo group. Patients who received quetiapine-XR had larger decreases in the number of drinking days/week (p = 0.17) and number of cannabis joints/week (p = 0.09) compared to those who received placebo. CONCLUSION Quetiapine-XR was superior to placebo in reducing QIDS-SR-16 total score in patients with a recent ALC/CAN. Patients taking quetiapine-XR used less alcohol and cannabis than patients on placebo, suggesting that quetiapine-XR may be of use in patients with bipolar disorder accompanied by GAD and other comorbidities.

Prog Neuropsychopharmacol Biol Psychiatry 2017; 76:80-87. [PMID: 28259723 DOI: 10.1016/j.pnpbp.2017.02.021] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/01/2016] [Revised: 02/23/2017] [Accepted: 02/28/2017] [Indexed: 10/20/2022]
Abstract
OBJECTIVE Anxiety disorders are among the most frequent psychiatric disorders. Current treatment guidelines recommend antidepressants, the calcium modulator gabapentin, and benzodiazepines as pharmacological treatments. However, delayed onset of action precludes the use of antidepressants as an acute treatment, while benzodiazepines can be recommended only as an emergency treatment due to their inherent risk of dependence. Therefore, an alternative pharmacological agent with acute efficacy is needed. Preliminary evidence points towards possible anxiolytic properties of the atypical antipsychotic quetiapine. The goals of this study were to test the acute anxiolytic properties of quetiapine in patients suffering from arachnophobia in a challenge paradigm, and to assess the effects of quetiapine on the central nervous fear network. METHODS In a randomized, double-blind, placebo-controlled proof-of-concept study, n=58 arachnophobic patients underwent an fMRI scan while looking at phobia-related and neutral stimuli. Subjective anxiety was evaluated retrospectively in questionnaires. RESULTS The functional imaging data revealed that patients showed stronger amygdala activation to phobia-related than to neutral stimuli. However, no effect of quetiapine on fear network activity was detected. Further, on questionnaire measures, quetiapine significantly reduced somatic anxiety symptoms, but had no effect on general psychological anxiety. CONCLUSION Viewing phobic pictures resulted in a robust amygdala activation in arachnophobic patients. Quetiapine seems to have no influence on activation in anxiety-related brain areas but appears to reduce acute somatic anxiety symptoms in patients with specific phobia. The central nervous correlates of the anxiolytic effects of quetiapine remain to be clarified in future studies.

Abstract
BACKGROUND Some studies have indicated the efficacy of quetiapine in the treatment of bipolar depression in adult patients. However, its efficacy has been not shown in child and adolescent patients. OBJECTIVE This systematic review purposefully determined the efficacy and acceptability of quetiapine in the treatment of children and adolescents with bipolar depression. DATA SOURCES A database search of EMBASE, PubMed, CINAHL, and Cochrane Controlled Trials Register was carried out in March 2016. All randomized controlled trials (RCTs) of bipolar depression in children and adolescents were considered for inclusion in this review. STUDY ELIGIBILITY CRITERIA PARTICIPANTS AND INTERVENTIONS RCTs of quetiapine in the treatment of child and adolescent patients with bipolar depression with end point outcomes were included in this study. Languages were not limited. STUDY APPRAISAL AND SYNTHESIS METHODS The full-text versions of relevant clinical studies were thoroughly examined and extracted. The primary efficacy of outcome was measured by using the pooled mean-changed scores of the rating scales for bipolar depression. However, the response and remission rates were also measured. RESULTS A total of 251 randomized patients in the three RCTs of quetiapine versus placebo in the treatment of bipolar depression for children and adolescents were eligible in this review. The pooled mean-changed score of the quetiapine-treated group was not greater than that of the placebo-treated group. Similarly, the pooled response and remission rates were not different between the two groups. The pooled overall discontinuation rate and the discontinuation rate due to adverse events were not different between the two groups. LIMITATIONS Limited studies were eligible in this review. CONCLUSION According to the findings in this review, quetiapine may not be efficacious in the treatment of bipolar depression in children and adolescents. Its acceptability, however, was comparable to a placebo. Therefore, the use of quetiapine in children and adolescents with bipolar depression is not recommended. Further well-defined clinical studies should be performed to confirm these outcomes.

Abstract
INTRODUCTION Case reports and poison center data have demonstrated that the second-generation antipsychotic quetiapine is being obtained and used for recreational abuse. The purpose of this study was to describe the relative rates of single-substance abuse for different atypical antipsychotics and compare their demographic and clinical features. METHODS We conducted a 10-year retrospective analysis of the National Poison Data System (NPDS) database (2003 - 2013). Trained nurses and pharmacists with specialty training in toxicology prospectively collect all NPDS data at poison control centers around the United States. We queried the NPDS for all cases of single-substance second-generation antipsychotic exposures coded as "intentional abuse." The data provided by the NPDS regarding rates and clinical features of quetiapine abuse and the abuse of all other second-generation antipsychotics were compared and described descriptively. RESULTS During the study period, 2,118 cases of quetiapine abuse and 1,379 cases of other second-generation antipsychotic abuse were identified. Quetiapine abuse was more common than the abuse of other second-generation antipsychotics, compromising 60.6% of all abuse cases during the study period. After quetiapine, the next most frequently abused medications were risperidone (530 cases, 15.2%) and olanzapine (246 cases, 7.0%). For all second-generation antipsychotics including quetiapine, central nervous system clinical effects were most common, including drowsiness, confusion, and agitation. Other serious clinical effects observed with second-generation antipsychotic abuse included hypotension, respiratory depression, and seizures. CONCLUSION Quetiapine abuse is relatively common, and is abused far more often than any other second-generation antipsychotic. Emergency physicians should be aware of the clinical effects that may occur after second-generation antipsychotic abuse.

Role and clinical implications of atypical antipsychotics in anxiety disorders, obsessive-compulsive disorder, trauma-related, and somatic symptom disorders: a systematized review. Int Clin Psychopharmacol 2016; 31:249-58.

Abstract
Atypical antipsychotics (AAs) may play a role in the treatment of anxiety disorders, obsessive-compulsive disorder (OCD), and trauma-related disorders. No reviews on their differential use in these different disorders have been performed recently. The aim of this systematized review was to obtain data on efficacy and comparative effectiveness of AAs as a treatment of anxiety disorders, OCD, and trauma-related disorders to provide guidance for clinicians on when and which AA to use. We searched on PubMed, Psychnet, and Cochrane Libraries from inception to July 2015. Search results were limited to randomized, placebo-controlled trials of adult patients. Evidence of efficacy was considered the presence of positive results in two or more double-blind placebo-controlled studies. Our systematized search identified 1298 papers, of which 191 were subjected to a full-text review and 56 were included. Quetiapine extended-release showed a role in both acute and maintenance treatment of uncomplicated generalized anxiety disorder, whereas more studies are needed before drawing practical recommendations on the use of olanzapine and risperidone; aripiprazole and risperidone are effective in resistant OCD as augmentation treatments. Risperidone and olanzapine add-on may have a role in resistant or chronic post-traumatic stress disorder patients, although only risperidone addition can be recommended on the basis of the criterion of two or more positive placebo-controlled trials. This systematized review supports the evidence that only a few AAs are effective in only a minority of the off-label conditions in which they are currently used and confirms that AAs are not all the same. Their use should be on the basis of a balance between efficacy and side effects, and the characteristics as well as the preference of the patient.

Abstract
This revision of previous algorithms for the pharmacotherapy of generalized anxiety disorder was developed by the Psychopharmacology Algorithm Project at the Harvard South Shore Program. Algorithms from 1999 and 2010 and associated references were reevaluated. Newer studies and reviews published from 2008-14 were obtained from PubMed and analyzed with a focus on their potential to justify changes in the recommendations. Exceptions to the main algorithm for special patient populations, such as women of childbearing potential, pregnant women, the elderly, and those with common medical and psychiatric comorbidities, were considered. Selective serotonin reuptake inhibitors (SSRIs) are still the basic first-line medication. Early alternatives include duloxetine, buspirone, hydroxyzine, pregabalin, or bupropion, in that order. If response is inadequate, then the second recommendation is to try a different SSRI. Additional alternatives now include benzodiazepines, venlafaxine, kava, and agomelatine. If the response to the second SSRI is unsatisfactory, then the recommendation is to try a serotonin-norepinephrine reuptake inhibitor (SNRI). Other alternatives to SSRIs and SNRIs for treatment-resistant or treatment-intolerant patients include tricyclic antidepressants, second-generation antipsychotics, and valproate. This revision of the GAD algorithm responds to issues raised by new treatments under development (such as pregabalin) and organizes the evidence systematically for practical clinical application.

Abstract
OBJECTIVE A number of atypical antipsychotic drugs were demonstrated to have anxiolytic effects in patients and in animal models. These effects were mostly suggested to be the consequence of the drugs' affinity to the serotonin system and its receptors. Asenapine is a relatively new atypical antipsychotic that is prescribed for schizophrenia and for bipolar mania. Asenapine has a broad pharmacological profile with significant effects on serotonergic receptors, hence it is reasonable to expect that asenapine may have some anxiolytic effects. The present study was therefore designed to examine possible effects of asenapine on anxiety-like behaviour of mice. METHOD Male ICR mice were repeatedly treated with 0.1 or 0.3 mg/kg injections of asenapine and then tested in a battery of behavioural tests related to anxiety including the open-field test, elevated plus-maze (EPM), defensive marble burying and hyponeophagia tests. In an adjunct experiment, we tested the effects of acute diazepam in the same test battery. RESULTS The results show that diazepam reduced anxiety-like behaviour in the EPM, the defensive marble burying test and the hyponeophagia test but not in the open field. Asenapine has anxiolytic-like effects in the EPM and the defensive marble burying tests but had no effects in the open-field or the hyponeophagia tests. Asenapine had no effects on locomotor activity. CONCLUSION The results suggest that asenapine may have anxiolytic-like properties and recommends that clinical trials examining such effects should be performed.

Abstract
BACKGROUND Quetiapine is an atypical antipsychotic that can stabilise mood from any index episode of bipolar disorder. This study investigated the effects of seven-day quetiapine administration on sleep, circadian rhythms and emotional processing in healthy volunteers. METHODS Twenty healthy volunteers received 150 mg quetiapine XL for seven nights and 20 matched controls received placebo. Sleep-wake actigraphy was completed for one week both pre-dose and during drug treatment. On Day 8, participants completed emotional processing tasks. RESULTS Actigraphy revealed that quetiapine treatment increased sleep duration and efficiency, delayed final wake time and had a tendency to reduce within-day variability. There were no effects of quetiapine on subjective ratings of mood or energy. Quetiapine-treated participants showed diminished bias towards positive words and away from negative words during recognition memory. Quetiapine did not significantly affect facial expression recognition, emotional word categorisation, emotion-potentiated startle or emotional word/faces dot-probe vigilance reaction times. CONCLUSIONS These changes in sleep timing and circadian rhythmicity in healthy volunteers may be relevant to quetiapine's therapeutic actions. Effects on emotional processing did not emulate the effects of antidepressants. The effects of quetiapine on sleep and circadian rhythms in patients with bipolar disorder merit further investigation to elucidate its mechanisms of action.

Abstract
BACKGROUND An increasing number of prescribers are using antipsychotics for treatment of anxiety disorders, despite lack of FDA-approved indications and mixed efficacy results from clinical trials. The objective of this study was to examine the prevalence of antipsychotics prescription in psychiatric inpatients and outpatients with anxiety disorders. METHODS This is a retrospective study of de-identified data from patients with a DSMIV-TR anxiety disorder diagnosis in an academic psychiatric setting in 2013. The final cohort of patients, after exclusion of bipolar/psychotic comorbidity, includes 1699 patients. Logistic regression models were used to explore associations between antipsychotic prescription and patient characteristics. RESULTS Among non-psychotic/non-bipolar patients with anxiety disorder, 53.6% of inpatients and 16.6% of outpatients received antipsychotic medication. Rates varied with the disorder. Outpatients with post-traumatic stress disorder (OR: 2.24, 95% CI: 1.66-3.01) and obsessive compulsive disorder (OR: 2.80, 95% CI: 1.86-4.19) received antipsychotic prescriptions more often than those without these diagnoses. Comorbidity with depression was common while comorbidity with borderline personality disorder was rare; both increased odds of receiving prescription of antipsychotics (OR: 1.57, 95% CI: 1.16-2.12 for depression; OR: 2.63, 95% CI 1.42-4.88 for borderline personality disorder, respectively). Additionally, age was significantly associated with increased odds of being on an antipsychotic. Quetiapine and aripripazole were the most prescribed antipsychotics and very few patients received rescue medication for extrapyramidal symptoms. LIMITATIONS Lack of specific indications for the psychotropic prescriptions. CONCLUSIONS A substantial percentage of patients with anxiety disorders are prescribed antipsychotics, especially among inpatients. This practice may reflect the severity of the anxiety disorder or the high prevalence of comorbidity. Based on frequency of rescue medication prescription, treatment seemed well tolerated for extra-pyramidal neurological side-effects.

Abstract
Background Some studies have indicated the efficacy of quetiapine in the treatment of generalized anxiety disorder (GAD). Objective The purpose of this study was to systematically review the efficacy, acceptability, and tolerability of quetiapine in adult patients with GAD. Methods The SCOPUS, MEDLINE, CINAHL, Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov databases were searched in April 2015. All randomized controlled trials (RCTs) of GAD were considered to be included in this meta-analysis. All RCTs of quetiapine in GAD patients providing endpoint outcomes relevant to severity of anxiety, response rate, remission rate, overall discontinuation rate, or discontinuation rate due to adverse events were included. The version reports from suitable clinical studies were explored, and the important data were extracted. Measurement for efficacy outcomes consisted of the mean-changed scores of the rating scales for anxiety, and response rate. Results A total of 2,248 randomized participants in three RCTs were included. The pooled mean-changed score of the quetiapine-treated group was greater than that of the placebo-treated group and comparable to selective serotonin reuptake inhibitors (SSRIs). Unfortunately, the response and the remission rates in only 50 and 150 mg/day of quetiapine-XR (extended-release) were better than those of the placebo. Their response and remission rates were comparable to SSRIs. The rates of pooled overall discontinuation and discontinuation due to adverse events of quetiapine-XR were greater than placebo. Only the overall discontinuation rate of quetiapine-XR at 50 and 150 mg/day and the discontinuation rate due to adverse events of quetiapine-XR at 50 mg/day were comparable to SSRIs. Conclusion Based on this meta-analysis, quetiapine-XR is efficacious in the treatment of GAD in adult patients. Despite its low acceptability and tolerability, the use of 50–150 mg/day quetiapine-XR for adult GAD patients may be considered as an alternative treatment. Further well-defined studies should be conducted to warrant these outcomes.

Abstract
BACKGROUND AND PURPOSE Quetiapine has a range of clinical activity distinct from other atypical antipsychotic drugs, demonstrating efficacy as monotherapy in bipolar depression, major depressive disorder and generalized anxiety disorder. The neuropharmacological mechanisms underlying this clinical profile are not completely understood; however, the major active metabolite, norquetiapine, has been shown to have a distinct in vitro pharmacological profile consistent with a broad therapeutic range and may contribute to the clinical profile of quetiapine. EXPERIMENTAL APPROACH We evaluated quetiapine and norquetiapine, using in vitro binding and functional assays of targets known to be associated with antidepressant and anxiolytic drug actions and compared these activities with a representative range of established antipsychotics and antidepressants. To determine how the in vitro pharmacological properties translate into in vivo activity, we used preclinical animal models with translational relevance to established antidepressant-like and anxiolytic-like drug action. KEY RESULTS Norquetiapine had equivalent activity to established antidepressants at the noradrenaline transporter (NET), while quetiapine was inactive. Norquetiapine was active in the mouse forced swimming and rat learned helplessness tests. In in vivo receptor occupancy studies, norquetiapine had significant occupancy at NET at behaviourally relevant doses. Both quetiapine and norquetiapine were agonists at 5-HT1A receptors, and the anxiolytic-like activity of norquetiapine in rat punished responding was blocked by the 5-HT1A antagonist, WAY100635. CONCLUSIONS AND IMPLICATIONS Quetiapine and norquetiapine have multiple in vitro pharmacological actions, and results from preclinical studies suggest that activity at NET and 5-HT1A receptors contributes to the antidepressant and anxiolytic effects in patients treated with quetiapine.

Abstract
INTRODUCTION Modest response and remission rates for the selective serotonin reuptake inhibitors and the serotonin-norepinephrine reuptake inhibitors, coupled with mounting evidence that the tolerability of the antidepressants (ADs) may have been overstated in the literature, has contributed to changes in prescribing patterns for generalized anxiety disorder (GAD). New interest in the absence of evidence that supports these standard therapies as superior to benzodiazepines stimulated a review of the literature. AREAS COVERED A literature search was conducted in the MedLine database with search terms 'generalized anxiety disorder' and 'treatment' for purposes of including relevant literature related to pharmacologic treatment of GAD. Aside from a review of pivotal literature, the authors also included newer studies that evaluated novel drug treatments. Last, the database was searched for benzodiazepine comparisons to standard therapy secondary to concerns that such literature is sparse. The review of newer modalities and the decision to include related literature was also based on the strength of the evidence and the status of their approval for the treatment of GAD. EXPERT OPINION Although ADs remain the most frequently prescribed medications for GAD, alternative and off-label therapies such as pregabalin, the atypical antipsychotics and vortioxetine are garnering interest. Based on the evidence available to us, it is our recommendation that along with the ADs, benzodiazepines be considered a possible first-line therapy in eligible patients based on the discretion and clinical judgment of the treating physician.

A sensitive method to simultaneously quantitate quetiapine and norquetiapine in rat plasma and brain tissue was developed using a one-step liquid-liquid extraction for sample preparation and LC-MS/MS for detection. The method provided a linear range of 1.0-500.0ng/mL for each analyte in plasma and 3.0-1500.0ng/g in brain tissue. The method was validated with precision within 15% relative standard deviation (RSD), accuracy within 15% relative error (RE), matrix effects within 10% and a consistent recovery. This method has been successfully applied in a preclinical study of quetiapine and norquetiapine to simultaneously determine their concentrations in rat plasma and brain tissue.

Abstract
Over the past years, international treatment guidelines have been established for the treatment of anxiety disorders. Nevertheless, little is known as to whether the actual inpatient treatment follows these guidelines. The main goal of this study was to answer the question whether patients with anxiety disorder are treated according to treatment guidelines. A total of 2,573 psychiatric inpatients with the diagnosis of anxiety disorder (920 men, 1,653 women) were identified on the basis of the data of the international drug safety programme in psychiatry AMSP. Of these patients, 25.3% presented with phobia, 26.6% with panic disorder, 18.7% with generalized anxiety disorder (GAD), and 29.4% with other diagnoses of anxiety. In all of the patients, 12.7% did not receive any psychotropic medication and 22.9% were not treated with antidepressants. Only 59.3% of patients with GAD, 73.9% of patients with panic disorder, and 52.1% of patients with phobia were treated according to diagnostic guidelines. The majority (60.3%) of all patients received one or two psychotropic drugs, and only 3.7% received five or more psychotropic drugs. In two groups of patients (one group with phobia and one with panic disorder), the annual prescription rate of antidepressants significantly increased over time. The prescription rate for anticonvulsants in patients with GAD increased from 0% in 1997 to 41.7% in 2011, and for antipsychotics, from 40.7% in 1997 to 47.2% in 2011. In particular, patients with GAD were commonly treated with antipsychotics.

Abstract
BACKGROUND Open-label quetiapine coadministration with SSRI therapy, in a diagnostically mixed sample of comorbid anxiety patients, offered additional anxiolytic benefit. Therefore, we designed the following controlled trial to confirm these findings in a comorbid, SSRI-resistant, panic disorder (PD) patient sample. METHODS This was a single-site, double-blind, placebo-controlled (PLAC), randomized, parallel group (2 groups), 8-week, quetiapine extended release (XR) coadministration trial. SSRI resistance was determined either historically or prospectively. Patients were randomized if they remained moderately ill (CGI-S score ≥ 4). Change in the PDSS scale total score was the primary efficacy outcome measure. Responders were identified as those with a ≥50 % decrease from their baseline PDSS score. In the early weeks of therapy, XR was flexibly and gradually titrated from 50 to 400 mg/day. RESULTS 43 patients were screened in total, and 26 of these were randomized and evaluable. 21 patients (78 % of the randomized group) completed the trial (10 XR; 11 PLAC). The endpoint quetiapine XR mean daily dose ± SD was 150 ± 106 mg. While, in the sample as a whole, there was improvement in PDSS scores across the 8-week trial (ANOVA main effect of time, F = 10.9, df 8,192, p < 0.0001), the treatment × time interaction effect was not statistically significant (F = 0.8, df 8,192, p = 0.61). There was no between-group difference in responder frequency at endpoint. CONCLUSIONS This proof-of-concept RCT did not support the efficacy of this treatment strategy for SSRI-resistant PD. Quetiapine XR was generally well-tolerated. Important limitations were the small sample size, and the relatively low average dose of quetiapine XR used. ClinicalTrials.gov ID#: NCT00619892.

Abstract
BACKGROUND AND OBJECTIVE Generalized anxiety disorder (GAD) is a psychiatric disorder characterized by excess worry and anxiety. GAD impacts overall health-related quality of life (HRQL), level of functioning, and disability. This literature review was conducted to understand the impact of pharmacological treatments on HRQL and functional outcomes. METHODS A literature review was conducted to identify randomized controlled trials (RCTs) comparing GAD pharmacological treatments with one or more patient-reported outcome (PRO) measure assessing HRQL, disability, functioning, or work productivity. Four databases were searched (PubMed, EMBASE, Cochrane Reviews, PsycInfo). Limits included English-language publications from 2004-2014. Abstracts and articles were reviewed to select articles reporting results of RCTs of pharmacological treatments for GAD that included one or more PRO measure. Article abstraction and summarization focused on key elements of the study design and PRO results. RESULTS One hundred sixty-three abstracts were reviewed; 44 articles were requested; 12 articles, representing 19 studies, were deemed relevant. The Sheehan Disability Scale (SDS) and the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q) were the most frequently utilized PRO measures. In clinical trials with significant anxiety symptom reductions, the SDS and Q-LES-Q also improved with treatment and differentiated from placebo. Two trials included a measure of work productivity; both demonstrated significant improvements with short-term treatment. CONCLUSION Treatments that reduce anxiety symptoms are also associated with improvements in patient-reported HRQL, function, and disability. In addition to evaluation of treatment impacts on anxiety symptoms, clinical trials should include PRO measures of HRQL, disability, and functioning.

Abstract
INTRODUCTION Second-generation antipsychotics (SGAs) are widely used in several psychiatric disease entities and exert to a different extent a risk for antipsychotic-induced weight gain (AIWG). As AIWG is associated with an increase in metabolic syndrome or cardiovascular events, knowledge of these risks is crucial for further monitoring and the initiation of counteractive measures. AREAS COVERED We searched PubMed and Web of Sciences for randomized-controlled trials and naturalistic observational studies published between 2010 and 2014 with sample sizes exceeding 100, including all marketed SGAs apart from zotepine, and providing data on weight increase. We also summarized relevant systematic reviews and meta-analyses of head-to-head comparisons. EXPERT OPINION Recently published data still support the hierarchical ranking of SGAs already proposed in previous reviews ranking clozapine and olanzapine as having the highest risk, followed by amisulpride, asenapine, iloperidone, paliperidone, quetiapine, risperidone and sertindole in the middle, and aripiprazole, lurasidone and ziprasidone with the lowest risk. Number needed to harm varied considerably in our meta-analysis. Younger patients and patients with a lower baseline body mass index are most vulnerable. The greatest amount of weight gain occurs within the first weeks of treatment. AIWG occurs in all diagnostic groups and is also common in treatment with first-generation antipsychotics; therefore, awareness of this adverse event is essential for anyone prescribing antipsychotics.

Abstract
BACKGROUND The use of antipsychotic drugs, particularly quetiapine, has increased at an unprecedented rate in the last decade, primarily in relation to nonpsychotic indications. This increased use is concerning because of the high rates of metabolic and extrapyramidal side effects and inadequate monitoring of these complications. The purpose of this study was to measure the use of quetiapine and other second-generation antipsychotics by primary care physicians and psychiatrists and the most common diagnoses associated with quetiapine recommendations. METHODS We analyzed data on antipsychotic use from the IMS Brogan Canadian CompuScript Database and the Canadian Disease and Treatment Index, with a focus on quetiapine. We looked at the number of dispensed prescriptions for second-generation antipsychotics written by primary care physicians and psychiatrists and the diagnoses associated with recommendations for quetiapine from 2005 to 2012. RESULTS Between 2005 and 2012, there was a 300% increase in dispensed prescriptions for quetiapine ordered by family physicians: from 1.04 million in 2005 to 4.17 million in 2012. In comparison, dispensed prescriptions from family physicians for risperidone increased 37.4%: from 1.39 million in 2005 to 1.91 million in 2012; those for olanzapine increased 37.1%, from 0.97 million in 2005 to 1.33 million in 2012. Dispensed prescriptions for quetiapine ordered by psychiatrists increased 141.6%: from 0.87 million in 2005 to 2.11 million in 2012. The top 4 diagnoses associated with quetiapine in 2012 were mood disorders, psychotic disorders, anxiety disorders and sleep disturbances. A 10-fold increase in quetiapine recommendations for sleep disturbances was seen over the study period, with almost all coming from family physicians. INTERPRETATION These findings indicate a preferential increase in the use of quetiapine over other antipsychotic drugs and show that most of the increased use is a result of off-label prescribing by family physicians.

Abstract
Benzodiazepines (BDZs) continue to be shrouded in controversy, mainly because of dependence associated with their long-term use and some of their side effects. Despite treatment recommendations favoring newer antidepressants, BDZs are still commonly prescribed for anxiety and related disorders. Recent studies have demonstrated that long-term use of BDZs for these conditions can be effective and safe and that BDZs can be combined with psychological therapy and antidepressants to produce optimal outcomes. Such findings, along with a failure to convincingly demonstrate the overall superiority of alternative pharmacotherapy for anxiety and related disorders, have given an impetus to a reconsideration of the role of BDZs. This article reviews BDZs and other pharmacotherapy options for anxiety and related disorders and suggests that treatment guidelines should acknowledge that BDZs can be used as first-line, long-term pharmacological treatment for panic disorder, generalized anxiety disorder and social anxiety disorder.

Abstract
This study is a pooled, post-hoc analysis evaluating once-daily extended release quetiapine fumarate (quetiapine XR) monotherapy in patients with generalized anxiety disorder (GAD). Three previously reported positive, 8-week, randomized, double-blind, placebo-controlled studies evaluated quetiapine XR therapy (50, 150, 300 mg/day) in patients with GAD [Hamilton Anxiety Rating Scale (HAM-A) total score ≥ 20]. Patients were stratified by baseline severity: HAM-A total score ≥ 22, ≥ 24, < 26, ≥ 26, ≥ 28. We report HAM-A total score change, response (≥ 50% reduction in HAM-A total score), and remission (HAM-A total score ≤ 7 and ≤ 9). Quetiapine XR significantly improved HAM-A total scores compared with placebo at Weeks 1 and 8 in the HAM-A ≥ 22, ≥ 24, and ≥ 26 cohorts (all doses), at Week 1 (all doses) and Week 8 (quetiapine XR 150 mg/day) in the < 26 cohort, and at Week 1 (all doses) and Week 8 (quetiapine XR 50 and 150 mg/day) in the HAM-A ≥ 28 group (P<0.05). Week 8 effect sizes for 50, 150, and 300 mg/day were as follows: 0.29, 0.47, 0.17 (HAM-A ≥ 22); 0.35, 0.55, 0.22 (HAM-A ≥ 24); 0.18, 0.32, 0.10 (HAM-A < 26); 0.41, 0.59, 0.24 (HAM-A ≥ 26); 0.60, 0.64, 0.22 (HAM-A ≥ 28), respectively. Acute quetiapine XR monotherapy significantly improves anxiety compared with placebo in patients with moderate or severe GAD, with symptom improvements seen as early as Week 1.

Abstract
Abstract
Objectives
The purpose of this study was to investigate the central activity of the two new imidazo[2,1-f]purine-2,4-dione derivatives behaved as presynaptic 5HT1A receptor agonists and postsynaptic 5HT1A, 5HT2A and D2 receptors antagonists. The compounds were examined using animal tests towards antipsychotic, antidepressant- and anxiolytic-like properties and then compared with effects evoked by an atypical antipsychotic drug ziprasidone.
Methods
D-amphetamine-induced hyperactivity test was used to determine antipsychotic-like activity of compounds 7 and 9. The forced swim test (FST) and the four-plate test were conducted to investigate antidepressant- and antianxiety-like activity, respectively, of studied agents. The investigated compounds 7, 9 and ziprasidone were administered intraperitoneally 60 min before the tests. Diazepam and imipramine were used as standard anxiolytic and antidepressant drugs, respectively.
Key findings
The obtained results demonstrate that new synthesized compound 9 evokes antipsychotic-like activity alike ziprasidone and, in contrary to the antipsychotic drug, shows antidepressant- and anxiolytic-like properties in behavioural tests in mice.
Conclusions
The present preclinical results indicate that one of the two investigated imidazo[2,1-f]purine-2,4-dione derivatives, compound 9, with methyl group at 7 position of imidazo[2,1-f]purine-2,4-dione fragment and the ortho-OCH3 substituent in the aryl moiety, acts as an antipsychotic drug with additional antidepressant and anxiolytic properties.

Abstract
OBJECTIVE Quetiapine is an atypical antipsychotic with demonstrated efficacy in the treatment of adolescent schizophrenia and pediatric bipolar mania. Large, placebo-controlled studies of interventions in pediatric bipolar depression are lacking. The current study investigated the efficacy and safety of quetiapine extended-release (XR) in patients 10-17 years of age, with acute bipolar depression. METHODS This multicenter, double-blind, randomized, placebo-controlled study investigated quetiapine XR (dose range, 150-300 mg/day) in pediatric outpatients with an American Psychiatric Association, Diagnostic and Statistical Manual of Mental Disorders, 4th ed., Text Revision (DSM-IV-TR) diagnosis of bipolar I or bipolar II disorder (current or most recent episode depressed) treated for up to 8 weeks (ClinicalTrials.gov identifier: NCT00811473). The primary study outcome was mean change in Children's Depression Rating Scale-Revised (CDRS-R) total score. Secondary efficacy outcomes included CDRS-R-based response and remission rates. RESULTS Of 193 patients randomized to treatment, 144 patients completed the study (75.3% of quetiapine XR group [n=70]; 74.0% of placebo group [n=74]). Least squares mean changes in CDRS-R total score at week 8 were: -29.6 (SE, 1.65) with quetiapine XR and -27.3 (SE, 1.60) with placebo, a between-treatment group difference of -2.29 (SE, 1.99; 95% CI, -6.22, 1.65; p=0.25; mixed-model for repeated measures analysis). Rates of response and remission did not differ significantly between treatment groups. The safety profile of quetiapine XR was broadly consistent with the profile reported previously in adult studies of quetiapine XR and pediatric studies of quetiapine immediate-release (IR). Potentially clinically significant elevations in clinical chemistry values included triglycerides (9.3%, quetiapine XR; 1.4%, placebo group) and thyroid stimulating hormone (4.7%, quetiapine XR; 0%, placebo group). An adverse event potentially related to diabetes mellitus occurred in 3.3% of the quetiapine XR versus no adverse events in the placebo group. CONCLUSIONS Quetiapine XR did not demonstrate efficacy relative to placebo in this 8 week study of pediatric bipolar depression. Quetiapine XR was generally safe and well tolerated.

Abstract
Evidence-based treatment approaches for generalized anxiety disorder (GAD) comprise psychotherapy, pharmacotherapy, or a combination of the two. First-line pharmacotherapy agents include selective serotonin reuptake inhibitors, selective serotonin-norepinephrine reuptake inhibitors, and, in certain European guidelines, pregabalin, which gained European Commission approval. Although short- and long-term efficacy have been established for these agents in controlled trials, response rates of 60-70 % are insufficient, remission rates are relatively modest, and relapse rates considerable. Moreover, questions increasingly arise regarding tolerability and side-effect profiles. As an alternative, antipsychotics have long been of interest for the treatment of anxiety disorders, but investigation had been tempered by their potential for irreversible side effects. With the improved side-effect profiles of atypical antipsychotics, these agents are increasingly being investigated across Axis I disorders. Atypical antipsychotics such as quetiapine, aripiprazole, olanzapine, and risperidone have been shown to be helpful in addressing a range of anxiety and depressive symptoms in individuals with schizophrenia and schizoaffective disorders, and have since been used in the treatment of a range of mood and anxiety disorders. In this article, we review the efficacy and tolerability of atypical antipsychotics as adjunctive therapy and/or monotherapy for individuals with GAD, a currently off-label indication. The most evidence has accumulated for quetiapine. Findings suggest that approximately 50 % of participants tolerate the side effects, most commonly sedation and fatigue. Among this subset, those who continue treatment demonstrate significant reductions in anxiety when used as adjunctive therapy or monotherapy. The appropriateness of the use of antipsychotics in the treatment of GAD is discussed.

Abstract
RATIONALE Previous open-label studies have suggested that quetiapine could be a valuable alternative for treating fibromyalgia. OBJECTIVE This study aims to compare the efficacy and tolerability of extended-release quetiapine with amitriptyline for treating fibromyalgia. METHODS This study was a randomized, open-label, flexible-dose, non-inferiority trial. Patients with fibromyalgia were randomized to receive quetiapine extended-release (XR) (N = 45) (50 to 300 mg daily) or amitriptyline (N = 45) (10 to 75 mg daily) for 16 weeks. The primary endpoint was the change from baseline to endpoint in the Fibromyalgia Impact Questionnaire (FIQ) total score; the non-inferiority threshold was established at 8 points. The secondary outcomes included sleep quality, anxiety, depression, and quality of life. RESULTS Twenty-two (49%) patients in the quetiapine group and 34 (76%) patients in the amitriptyline group completed the study. We found a reduction of 9.8 points in the total FIQ score at the endpoint for the quetiapine-treated patients compared to 13.9 points for the amitriptyline-treated patients, for a difference of 4.14 points (80% confidence interval (CI) -0.70 to 8.98). No significant differences were found between the quetiapine XR and amitriptyline groups for any of the secondary outcomes. The proportion of patients discontinuing treatment due to adverse events was higher in the quetiapine group (n = 14, 31.1%) than the amitriptyline group (n = 3, 6.6%). CONCLUSIONS Our results appear to indicate that quetiapine XR does not provide similar efficacy to amitriptyline for treating patients with fibromyalgia. Quetiapine XR had a worse tolerability than amitriptyline in this population, possibly due to a relatively high starting dose.

Abstract
OBJECTIVES To evaluate quetiapine XR in patients with anxious depression, as defined by HAM-A total and HAM-D anxiety/somatisation factor scores. METHODS Post hoc analyses of pooled data from two 6-week, double-blind, randomised, placebo-controlled studies of adjunctive quetiapine XR (150 or 300 mg/day) in patients with MDD and inadequate response to antidepressants. Patients were stratified in a primary analysis using HAM-A (HAM-A total score at baseline ≥ 20 ["high"] or < 20 ["low"]) and a secondary analysis using HAM-D (anxious depression defined as HAM-D anxiety/somatisation factor score ≥ 7). Outcomes included change in MADRS total score. RESULTS In patients with high anxiety levels (HAM-A total score ≥ 20), reductions in MADRS total score were -15.20 (P = 0.122) and -15.92 (P < 0.05) for quetiapine XR 150 and 300 mg/day, respectively, vs. placebo (-13.49). In patients with low levels of anxiety (HAM-A total score < 20), both quetiapine XR doses (P < 0.001) improved MADRS total scores vs. placebo. In the secondary analysis, quetiapine XR 150 (P < 0.01) and 300 mg/day (P < 0.001) improved MADRS total score vs. placebo in patients with HAM-D anxiety/somatisation factor score ≥ 7. CONCLUSIONS Adjunct quetiapine XR demonstrates efficacy in patients with anxious and non-anxious depression, assessed using HAM-A total score, and anxious depression assessed using HAM-D anxiety/somatisation factor score.

Effects of extended-release quetiapine fumarate on long-term functioning and sleep quality in patients with Generalized Anxiety Disorder (GAD): data from a randomized-withdrawal, placebo-controlled maintenance study. J Affect Disord 2013; 151:906-13. [PMID: 24135509 DOI: 10.1016/j.jad.2013.07.037] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/10/2013] [Accepted: 07/31/2013] [Indexed: 11/26/2022]
Abstract
BACKGROUND This analysis evaluated effects of quetiapine XR maintenance treatment on functioning and sleep in patients with GAD. METHODS Analysis of patient-reported data from a randomized-withdrawal, double-blind, placebo-controlled study of quetiapine XR monotherapy in GAD. Following open-label run-in (4-8 weeks) and a 12-18-week stabilization phase (quetiapine XR 50, 150, or 300 mg/day), eligible patients were randomized to continue on quetiapine XR or receive placebo for up to 52 weeks. Primary variable was time to an anxiety event. Secondary variables included the Sheehan Disability Scale (SDS) and Pittsburgh Sleep Quality Index (PSQI). RESULTS In total, 432 patients were randomized (quetiapine XR, N=216; placebo, N=216). The risk of an anxiety event was significantly reduced for quetiapine XR vs. placebo (HR 0.19; 95% CI 0.12, 0.31; p<0.001). Quetiapine XR was more effective than placebo at maintaining SDS total scores (LSM change: -0.19 vs. 1.01; p=0.017) and non-work-related SDS domain score 'family life/home responsibilities' (-0.13 vs. 0.32; p=0.011), but not 'social life' (0.05 vs. 0.34; p=0.114). Quetiapine XR was more effective than placebo at maintaining the work-related SDS domain score 'days lost' (-0.05 vs. 0.11; p=0.027), but not 'work/school' (-0.10 vs. 0.29; p=0.051) or 'days underproductive' (0.06 vs. 0.13; p=0.619). PSQI global scores were reduced from randomization with quetiapine XR vs. placebo (0.39 vs. 1.60; p<0.001). LIMITATIONS Lack of active-comparator arm, exclusion of patients with comorbid depression. CONCLUSIONS In patients with GAD, long-term treatment with quetiapine XR (50-300 mg/day) monotherapy was effective at maintaining improvements in functioning and sleep quality.

Abstract
Anxiety disorders are among the most frequent psychiatric disorders. With regard to pharmacological treatment, antidepressants, the calcium modulator pregabalin and benzodiazepines are recommended according to current treatment guidelines. With regard to acute states of anxiety, so far practically only benzodiazepines provide an immediate anxiolytic effect. However, the risk of tolerance and dependency limits the use of this class of medication. Therefore, there is still a need for alternative pharmacologic strategies. Increasing evidence points towards anxiety-reducing properties of atypical antipsychotics, particularly quetiapine. Therefore, we aimed to evaluate the putative acute anxiolytic effects of this compound, choosing the induction of acute anxiety in patients with specific phobia as a model for the evaluation of ad-hoc anxiolytic properties in a proof-of-concept approach. In a randomized, double-blind, placebo-controlled study, 58 patients with arachnophobia were treated with a single dose of quetiapine XR or placebo prior to a virtual reality spider challenge procedure. Treatment effects were monitored using rating scales for acute anxiety as well as measurements of heart rate and skin conductance. Overall, quetiapine showed significant anxiolytic effects compared to placebo. However, effects were not seen on the primary outcome measure (VAS Anxiety), but were limited to somatic anxiety symptoms. Additionally, a significant reduction of skin conductance was observed. Further exploratory analyses hint towards a mediating role of the (COMT) val158met genotype on treatment response. The present results thus suggest a possible suitability of quetiapine in the acute treatment of anxiety, particularly with regard to somatic symptoms.
