Lin CY, Chiang CH, Tseng MCM, Tam KW, Loh EW. Effects of quetiapine on sleep: A systematic review and meta-analysis of clinical trials. Eur Neuropsychopharmacol 2023; 67:22-36. [PMID: 36463762 DOI: 10.1016/j.euroneuro.2022.11.008] [Citation(s) in RCA: 10] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/02/2022] [Revised: 11/11/2022] [Accepted: 11/15/2022] [Indexed: 12/03/2022]
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).

Comparative Remission Rates and Tolerability of Drugs for Generalised Anxiety Disorder: A Systematic Review and Network Meta-analysis of Double-Blind Randomized Controlled Trials. Front Pharmacol 2020; 11:580858. [PMID: 33343351 PMCID: PMC7741609 DOI: 10.3389/fphar.2020.580858] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2020] [Accepted: 09/23/2020] [Indexed: 12/14/2022] Open
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.

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
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
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.

A placebo controlled study of quetiapine-XR in bipolar depression accompanied by generalized anxiety with and without a recent history of alcohol and cannabis use. Psychopharmacology (Berl) 2017; 234:2233-2244. [PMID: 28536866 DOI: 10.1007/s00213-017-4642-5] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/17/2017] [Accepted: 04/25/2017] [Indexed: 11/26/2022]
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.

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
Three second-generation antipsychotic (SGA) agents have received FDA approval for adjunctive treatment, to antidepressant, of major depressive disorder: quetiapine, aripiprazole, and olanzapine. Additionally, quetiapine and lurasidone have been approved for the treatment of bipolar depression. There are data suggesting that quetiapine is effective for major depressive disorder as monotherapy. These agents are effective for depression only at subantipsychotic doses. Receptor profiles predict that all SGA will have anxiolytic effects as subantipsychotic doses but that all will be dysphorogenic at full antipsychotic doses (i.e., produce a depression-like clinical picture). The antidepressant effect appears to be unique to some agents, with direct evidence of insignificant antidepressant action for ziprasidone. Three general principles can guide the use of antipsychotics as antidepressants: (i) All SGAs may have anxiolytic effects; (ii) full antipsychotic doses are dysphorogenic, and therefore, subantipsychotic doses are to be used; and (iii) SGAs do not have a general antidepressant effect, rather, this appears to be unique to quetiapine and aripiprazole, and possibly lurasidone.

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
BACKGROUND A large and extensive body of research has examined comorbid anxiety and depression in adults. Children and adolescents also frequently present with comorbid anxiety and depression; however, research and treatment require unique environmental and neurodevelopmental considerations in children. As a result, our understanding of comorbid anxiety and depression in children and adolescents is limited. OBJECTIVE The goal of this systematic review was to examine the current literature focused on comorbid anxiety and depression in children and adolescents. The review included theoretical conceptualizations as well as diagnostic, neurobiological, prevention, and treatment considerations. In addition, a proposed algorithm for the treatment of comorbid anxiety and depression in children/adolescents is provided. METHODS This systematic literature review included 3 discrete searches in Ovid SP Medline, PsycInfo, and PubMed. RESULTS The review included and synthesized 115 articles published between 1987 and 2015. The available evidence suggests that anxiety and depression are common in clinical populations of children and adolescents, and that comorbidity is likely underestimated in children and adolescents. Children and adolescents with comorbid anxiety and depression have unique presentations, greater symptom severity, and treatment resistance compared with those who have either disease in isolation. A dimensional approach may be necessary for the future development of diagnostic strategies and treatments for this population. Nascent neuroimaging work suggests that anxiety and depression each represents a distinct neurobiological phenotype. CONCLUSIONS The literature that is currently available suggests that comorbid anxiety and depression is a common presentation in children and adolescents. This diagnostic picture underscores the importance of comprehensive dimensional assessments and multimodal evidence-based approaches given the high disease severity. Future research on the neurobiology and the treatment of these common clinical conditions is warranted.

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
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.

Abstract
INTRODUCTION Anxiety disorders are among the most prevalent and disabling psychiatric disorders in the United States and worldwide. Basic research has provided critical insights into the mechanism regulating fear behavior in animals and a host of animal models have been developed in order to screen compounds for anxiolytic properties. Despite this progress, no mechanistically novel agents for the treatment of anxiety have come to market in more than two decades. AREAS COVERED The current review will provide a critical summary of current pharmacological approaches to the treatment of anxiety and will examine the pharmacotherapeutic pipeline for treatments in development. Anxiety and related disorders considered herein include panic disorder, social anxiety disorder, generalized anxiety disorder and post-traumatic stress disorder. The glutamate, neuropeptide and endocannabinoid systems show particular promise as future targets for novel drug development. EXPERT OPINION In the face of an ever-growing understanding of fear-related behavior, the field awaits the translation of this research into mechanistically novel treatments. Obstacles will be overcome through close collaboration between basic and clinical researchers with the goal of aligning valid endophenotypes of human anxiety disorders with improved animal models. Novel approaches are needed to move basic discoveries into new, more effective treatments for our patients.

Abstract
The aim of the present review was to discuss the following aspects of treatment with quetiapine in psychiatric disorders: i) Neurocognition and functional recovery in bipolar disorder (BD); ii) neuroprotective profile in different models; and iii) potential off-label indications. A PubMed search was conducted of articles published in English between 2000 and 2012 on quetiapine, cross-referenced with the terms ‘anxiety’, ‘attention deficit disorder’, ‘borderline personality disorder’, ‘dementia’, ‘insomnia’, ‘major depressive disorder’ (MDD), ‘obsessive-compulsive disorder’, ‘post-traumatic stress disorder’, ‘remission’, ‘cognition’, ‘neurobiology’, ‘neuroprotection’, ‘efficacy’ and ‘effectiveness’. Articles were selected from meta-analyses, randomized clinical trials and open trials, and the results were summarized. Quetiapine, when studied in off-label conditions, has shown efficacy as a monotherapy in MDD and general anxiety disorder. Quetiapine also appears to exhibit a small beneficial effect in dementia. The review of other conditions was affected by methodological limitations that precluded any definitive conclusions on the efficacy or safety of quetiapine. Overall, the present review shows evidence supporting a potential role for quetiapine in improving cognition, functional recovery and negative symptoms in a cost-effective manner in BD. These benefits of quetiapine are potentially associated with its well-described neuroprotective effects; however, further studies are clearly warranted.

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
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
OBJECTIVE Many studies have investigated the efficacy and tolerability of alternative pharmacotherapy for panic disorder. This study aims to provide a comprehensive review of the existing literature regarding the efficacy and tolerability of atypical antipsychotics for panic disorder. METHODS We searched for relevant published articles using Medline, the Cochrane database, and EMBASE on 19 June 2013. Prospective studies that examined the efficacy and tolerability of atypical antipsychotics in the treatment of primary panic disorder or comorbid panic disorder (or symptoms) in other psychiatric disorders were included in this review. RESULTS Seven prospective studies were included in this review. Among these, four were open-label studies for refractory panic disorder. Two of the seven included studies were randomized controlled trials among patients with panic symptoms comorbid with bipolar disorder. The remaining study was a randomized controlled trial for panic disorder or panic attack comorbid with major depression. Except one negative risperidone study, the reviewed studies showed the favorable efficacy results of atypical antipsychotics. CONCLUSIONS Although the majority of the evidence regarding the efficacy of atypical antipsychotics in the treatment of panic disorder comes from small, open-label studies, this review suggests the potential role of atypical antipsychotics in treating panic disorder.

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
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.

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
OBJECTIVES A series of studies were conducted to guide the development and characterise the pharmacokinetics of extended-release quetiapine fumarate (quetiapine XR), a once-daily formulation to control the release of the drug. METHODS Data from these studies are described and discussed herein. RESULTS Once-daily quetiapine XR produced a similar area under the plasma concentration-time curve (AUC), minimum plasma concentration (Cmin) and a slightly lower maximum plasma concentration (Cmax) than the equivalent dose of immediate-release quetiapine (quetiapine IR) given twice daily. In a crossover, head-to-head study, total daily exposure, measured by AUC at steady state, was less variable with quetiapine XR versus quetiapine IR (percent coefficient of variation 39.2% versus 51.2%, respectively). Compared with fasting, a high-fat meal increased the AUC and Cmax for quetiapine XR, whereas a light meal had no significant effect on these parameters. Quetiapine XR exhibits a less pronounced D2 receptor occupancy peak and receptor occupancy levels remain higher for longer compared with quetiapine IR. Quetiapine XR was generally well tolerated with a safety profile similar to quetiapine IR, although the intensity of sedation in the first hours of treatment was significantly lower (p < 0.01) with quetiapine XR versus IR. CONCLUSION At steady state, quetiapine XR provided a similar AUC and Cmin and a slightly lower Cmax relative to an equivalent dose of quetiapine IR administered twice daily. Quetiapine XR exhibited linear pharmacokinetics in the dose range tested and no food effect was observed with a light meal. Once-daily dosing and simpler dose titration makes using quetiapine XR convenient for clinicians and patients. Quetiapine XR has predictable pharmacokinetics and was generally well tolerated, with significantly lower intensity of sedation after the first hours of administration compared with quetiapine IR. With once-daily quetiapine XR, the impact of daytime sedation may be mitigated by evening dosing.

Abstract
OBJECTIVE The objective of the study was to evaluate once-daily extended release quetiapine fumarate (quetiapine XR) monotherapy in older patients with generalized anxiety disorder (GAD). METHODS An 11-week (9-week treatment; 2-week posttreatment), randomized, double-blind, placebo-controlled study (D1448C00015) of flexibly-dosed quetiapine XR (50-300 mg/day) or placebo conducted at 47 sites (Estonia, Poland, Russia, Ukraine, and USA) between September 2006 and April 2008. Patients (≥66 years) with DSM-IV diagnosis of GAD, Hamilton Anxiety Rating Scale (HAM-A) total score of ≥20 with item 1 (anxious mood) and 2 (tension) scores of ≥2, Clinical Global Impressions-Severity of Illness (CGI-S) score of ≥4, and Montgomery Åsberg Depression Rating Scale (MADRS) total score of ≤16 were eligible for inclusion. Primary endpoint: week 9 change from randomization in HAM-A total score. RESULTS Patients were randomized to quetiapine XR (n = 223) or placebo (n = 227). At week 9, quetiapine XR significantly reduced HAM-A total score versus placebo (least squares mean -14.97 versus -7.21; p < 0.001); symptom improvement with quetiapine XR versus placebo was significant at week 1 (p < 0.001). At week 9, quetiapine XR demonstrated significant benefits over placebo for HAM-A response and remission rates, HAM-A psychic and somatic cluster, MADRS total, CGI-S, Pittsburgh Sleep Quality Index global, pain visual analog scale, and Quality of Life, Enjoyment and Satisfaction Questionnaire short form % maximum total scores and Clinical Global Impressions-Improvement (% patients with a score of 1/2) (all p < 0.001). Adverse events (>5% in either treatment group) included somnolence, dry mouth, dizziness, headache, and nausea. CONCLUSIONS Quetiapine XR (50-300 mg/day) monotherapy is effective in the short term in improving symptoms of anxiety in older patients with GAD, with symptom improvement seen as early as week 1. Tolerability findings were generally consistent with the known profile of quetiapine.

Abstract
BACKGROUND Generalized anxiety disorder (GAD) is one of the most prevalent anxiety disorders, with important implications for patients and healthcare resources. However, few economic evaluations of pharmacological treatments for GAD have been published to date, and those available have assessed only a limited number of drugs. OBJECTIVE To assess the cost effectiveness of pharmacological interventions for patients with GAD in the UK. METHODS A decision-analytic model in the form of a decision tree was constructed to compare the costs and QALYs of six drugs used as first-line pharmacological treatments in people with GAD (duloxetine, escitalopram, paroxetine, pregabalin, sertraline and venlafaxine extended release [XL]) and 'no pharmacological treatment'. The analysis adopted the perspective of the NHS and Personal Social Services (PSS) in the UK. Efficacy data were derived from a systematic literature review of double-blind, randomized controlled trials and were synthesized using network meta-analytic techniques. Two network meta-analyses were undertaken to assess the comparative efficacy (expressed by response rates) and tolerability (expressed by rates of discontinuation due to intolerable side effects) of the six drugs and no treatment in the study population. Cost data were derived from published literature and national sources, supplemented by expert opinion. The price year was 2011. Probabilistic sensitivity analysis was conducted to evaluate the underlying uncertainty of the model input parameters. RESULTS Sertraline was the best drug in limiting discontinuation due to side effects and the second best drug in achieving response in patients not discontinuing treatment due to side effects. It also resulted in the lowest costs and highest number of QALYs among all treatment options assessed. Its probability of being the most cost-effective drug reached 75 % at a willingness-to-pay threshold of £20,000 per extra QALY gained. CONCLUSION Sertraline appears to be the most cost-effective drug in the treatment of patients with GAD. However, this finding is based on limited evidence for sertraline (two published trials). Sertraline is not licensed for the treatment of GAD in the UK, but is commonly used by primary care practitioners for the treatment of depression and mixed depression and anxiety.

Abstract
BACKGROUND Generalized anxiety disorder (GAD) is a common and serious disease with a lifetime prevalence of 4.3% to 5.9%. It is underdiagnosed in primary care. METHODS Recommendations on the treatment of GAD are given on the basis of all available findings from pertinent randomized trials, retrieved by a selective search of the literature. RESULTS Among psychotherapeutic techniques, various kinds of cognitive behavioral therapy (CBT) have been found useful in controlled trials. The drugs of first choice include selective serotonin reuptake inhibitors (SSRIs), serotonin-norepinephine reuptake inhibitors (SNRIs), and the calcium-channel modulator pregabalin. Tricyclic antidepressants are also effective but have more adverse effects than SSRIs. Although benzodiazepines are effective anxiolytic agents for short-term use, they should not be given over the long term because of the danger of addiction. Buspirone, an azapirone, was found to be effective in a small number of trials, but the findings across trials are inconsistent. The response rate of GAD to CBT in published studies lies between 47% and 75%, while its response rate to drug treatment lies between 44% and 81%. CONCLUSION The treatment of GAD with CBT and drugs is evidence-based and has a good chance of improving the manifestations of the disorder.

Abstract
BACKGROUND Comorbid anxiety symptoms,in patients with a primary anxiety disorder or a mood disorder, leads to poor patient outcomes and burdens the healthcare system. This pilot study evaluated the feasibility of extended-release quetiapine fumarate (quetiapine XR) for the treatment of patients with either a primary anxiety disorder or a mood disorder with comorbid anxiety symptoms compared to a placebo, as an adjunct to antidepressant therapy. METHODS Thirty-nine patients with a diagnosis of a primary anxiety disorder or a mood disorder with comorbid anxiety symptoms were enrolled in this study. Patients with a stable dose of antidepressant therapy were randomized according to a 2:1 probability of receiving either quetiapine XR or a placebo adjunctive treatment for 8 weeks. The efficacy was assessed by the Hamilton Anxiety Rating Scale (HAM-A) and the Clinical Global Impression of severity (CGI-S) score at baseline, week 1, 4, and 8. RESULTS A total of 35 patients were included in this intention-to treat (ITT) population for the efficacy analysis (quetiapine XR: 22 patients; placebo: 13 patients). At week 4, statistically significant differences were observed on both the HAM-A score (p = 0.003) and the CGI-S score (p = 0.025), favouring the quetiapine XR (-13.00 ± 4.14) compared to placebo (-6.63 ± 5.42). However, no statistically significant difference was observed between the two groups with regard to changes from the baseline to week 8 on the HAM-A score (p = 0.332) or the CGI-S score (p = 0.833). CONCLUSIONS Augmentation of antidepressant treatment with quetiapine XR did not result in clinical improvement according to the outcome measure of anxiety using the HAM-A and CGI-S scores at week 8, among the patients with either a primary anxiety disorder or a mood disorder with comorbid anxiety symptoms. However, treatment with quetiapine XR as an adjunct to antidepressant therapy appeared to provide a short-term benefit at 4 weeks. Further study is needed with a larger sample size, randomized controlled design and control of the dosage prescribed. TRIAL REGISTRATION Clinicaltrials.gov identifier: NCT00912535.

Abstract
BACKGROUND We evaluated the effects of once-daily extended-release quetiapine fumarate (quetiapine XR) on patient-reported outcomes in generalized anxiety disorder (GAD). METHODS This is a report of a pooled analysis from three acute 8-week, randomized, placebocontrolled, fixed-dose (50, 150, 300 mg/day) studies and a 52-week maintenance flexible dose (50-300 mg/day) study of quetiapine XR monotherapy in patients with GAD. Quality of Life Enjoyment and Satisfaction Questionnaire Short Form (Q-LES-Q-SF) percent maximum total scores (items 1-14), item 15 ("satisfaction with medication"), item 16 ("overall life satisfaction"), and Pittsburgh Sleep Quality Index (PSQI) global scores are reported. Sheehan Disability Scale (SDS) total scores were also assessed (maintenance study only). RESULTS The acute studies showed significant improvements at week 8 in Q-LES-Q-SF percent maximum total score with quetiapine XR 150 mg/day (P < 0.001) and item 16 with quetiapine XR 50 (P < 0.05) and 150 mg/day (P < 0.001) versus placebo; PSQI global scores significantly improved with quetiapine XR 50, 150, and 300 mg/day versus placebo (P < 0.001). The maintenance study showed significant benefits versus placebo with quetiapine XR 50-300 mg/day in Q-LES-Q-SF percent total score, item 15 and item 16 scores, PSQI global score, and SDS total score. CONCLUSION Quetiapine XR 150 mg/day (acute studies) and 50-300 mg/day (maintenance study) improved quality of life, overall functioning, and sleep quality in patients with GAD.

Depress Anxiety 2012; 29:574-86. [PMID: 22753280 DOI: 10.1002/da.21970] [Citation(s) in RCA: 28] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/13/2011] [Revised: 04/26/2012] [Accepted: 05/12/2012] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND A pooled analysis was performed on data from two studies evaluating the efficacy of once-daily extended-release quetiapine fumarate (quetiapine XR) monotherapy for patients with major depressive disorder. Through these analyses (based on Hamilton Rating Scale for Depression (HAM-D) and Hamilton Rating Scale for Anxiety (HAM-A) measures), we aim to further evaluate the efficacy of quetiapine XR in depressed patients with high levels of anxiety symptoms. METHODS Secondary analyses were conducted of pooled individual patient data from two 8-week (6-week randomized phase, 2-week drug discontinuation phase), double-blind, placebo-controlled studies of quetiapine XR (50-300 mg/day). Outcomes included change from randomization at Week 6 in Montgomery Åsberg Depression Rating Scale (MADRS) total score for patients with anxious and nonanxious depression. RESULTS Of 968 patients included in the analysis, 788 (81.4%) were classified as anxious depressed (defined as HAM-D anxiety/somatization factor score ≥ 7) and 180 (18.6%) were nonanxious. For patients with anxious depression and nonanxious depression, statistically significant differences versus placebo in MADRS total score were recorded for quetiapine XR 150 mg/day (-3.24, P < .001 and -4.82, P < .01, respectively) and 300 mg/day (-3.57, P < .001 and -3.39, P < .05, respectively) at Week 6. In the second analysis using an alternate definition of anxious depression (baseline HAM-A total score ≥ 20), quetiapine XR 150 and 300 mg/day resulted in significant differences versus placebo in MADRS total score reduction in patients with high and lower levels of anxiety. The adverse event (AE) profile was similar irrespective of baseline anxiety levels, although patients with anxious depression reported a somewhat greater incidence of AEs. CONCLUSION Quetiapine XR monotherapy improved symptoms of depression in patients with higher and lower levels of anxiety.

Abstract
OBJECTIVE Prospectively planned pooled analysis evaluating efficacy and tolerability of acute quetiapine XR monotherapy in generalised anxiety disorder. METHODS Data from three 10-week, randomised, double-blind, placebo-controlled studies of similar design were analysed. RESULTS At Week 8, Hamilton Anxiety Rating Scale (HAM-A) total score significantly improved with quetiapine XR: least squares means change -13.31, p < 0.001 (50 mg/day, n = 452), -14.39, p < 0.001 (150 mg/day, n = 673) and -12.50, p < 0.05 (300 mg/day, n = 444) versus -11.30 placebo; significant (p < 0.001, n = 665) improvements versus placebo were observed with each dose at Week 1. Significant improvements versus placebo at Week 8 are as follows: HAM-A psychic symptom subscale, Montgomery-Åsberg Depression Rating Scale total, Pittsburgh Sleep Quality Index global scores for all quetiapine XR doses; HAM-A response and remission rates, HAM-A somatic symptom subscale score, Clinical Global Impression-Severity of Illness total score, % patients with Clinical Global Impression-Improvement score ≤2 with quetiapine XR 50 and 150 mg/day; and Quality of Life Enjoyment and Satisfaction Questionnaire short form % maximum total score with quetiapine XR 150 mg/day. In the quetiapine XR 50, 150 and 300 mg/day and placebo groups, 13.2%, 16.5%, 24.0% and 5.4% of patients discontinued because of an adverse event, and 1.9%, 1.4%, 3.7% and 1.8% of patients experienced clinically significant changes in glucose. The most common adverse events with quetiapine XR included dry mouth, somnolence, sedation and constipation. CONCLUSION Quetiapine XR monotherapy reduced the symptoms of generalised anxiety disorder, with improvement from Week 1. Adverse events were consistent with the known tolerability profile of quetiapine.

Abstract
Effective management of schizophrenia remains a significant clinical challenge. While antipsychotic medications have proven efficacy in this disease, there remains an opportunity to further improve symptom control and long-term relapse prevention. Also, a number of factors, including tolerability and complex dosing regimens, can result in nonadherence to medication. Quetiapine is an atypical antipsychotic with proven efficacy and an established tolerability profile in schizophrenia. The once-daily extended-release formulation (quetiapine XR) offers a simplified dosing regimen and titration schedule. Short-term clinical studies have shown that quetiapine XR (400-800 mg/d) is efficacious in the acute treatment of schizophrenia, while a long-term study has shown that quetiapine XR was significantly more effective than placebo at preventing relapse. Furthermore, an investigation in which stable patients switched from the immediate-release formulation (quetiapine IR) to quetiapine XR showed that quetiapine XR is generally well tolerated and has no loss of efficacy compared with quetiapine IR. In patients who experienced insufficient efficacy or poor tolerability on their previous antipsychotic, switching to quetiapine XR significantly improved efficacy compared with the previous treatment. In conclusion, quetiapine XR is an effective and generally well tolerated treatment for schizophrenia. Furthermore, once-daily dosing may improve patient adherence, which may impact positively on patient outcomes.
