Identifying differential predictors for treatment response to amisulpride and olanzapine combination treatment versus each monotherapy in acutely ill patients with schizophrenia: Results of the COMBINE-study. Schizophr Res 2024; 270:383-391. [PMID: 38986385 DOI: 10.1016/j.schres.2024.06.033] [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: 11/25/2023] [Revised: 06/19/2024] [Accepted: 06/22/2024] [Indexed: 07/12/2024]
Abstract
BACKGROUND Extensive research has been undertaken to predict treatment response (TR) to antipsychotics. Most studies address TR to antipsychotics in general and as monotherapy, however, it is unknown whether patients might respond favourably to a combination of antipsychotics. AIMS This study aimed to identify differential predictors for TR to monotherapy with amisulpride or olanzapine compared to a combination of antipsychotics. METHODS Post-hoc analysis was conducted of data collected from the COMBINE-study, a double-blind, randomized, controlled trial. Demographic and disease-related measures were gathered at baseline to predict TR after eight weeks defined by the Positive and Negative Syndrome Scale. Missing values were accounted for by a random replacement procedure. Attrition effects and multicollinearity were analysed and sets of logistic regression models were calculated for different treatment groups. RESULTS Of the 321 randomized patients, 201 completed procedures until week eight and 197 were included in the analyses. For all treatment groups, early TR after two weeks and high subjective well-being under antipsychotics at baseline were robust predictors for TR. The propensity for early side effects also indicated a higher risk of later non-response. Specific parameter estimates were rather similar between treatment groups. CONCLUSION Early TR, drug-related subjective well-being, and early side effect propensity evolved as predictors for later TR whether to monotherapy or combination strategy. Accordingly, due to a lack of differential predictors, early and close monitoring of targeted and unwanted effects is indicated to guide respective treatment decisions.

Eserian JK, Blanco VP, Mercuri LP, Matos JDR, Galduróz JCF. Current strategies for tapering psychiatric drugs: Differing recommendations, impractical doses, and other barriers. Psychiatry Res 2023; 329:115537. [PMID: 37837810 DOI: 10.1016/j.psychres.2023.115537] [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: 08/01/2023] [Revised: 09/26/2023] [Accepted: 10/07/2023] [Indexed: 10/16/2023]
Abstract
While effective ways to prevent withdrawal symptoms from psychiatric drugs remain unclear, a highly accepted clinical approach for treatment discontinuation is to gradually reduce doses over time. The objective of this review is to gather the current strategies for tapering of psychiatric drugs described in the literature and guidelines in an attempt to identify the most promising one. Literature review and search for practice guidelines provided by government agencies and medical organizations were performed. Different strategies for tapering were found: linear tapering, hyperbolic tapering (by exponential dose reduction and pre-established dose-response curves), extended dosing, and substitution for a long half-life drug. The use of guidelines offers support for patients and prescribers, increasing the likelihood of achieving effective drug discontinuation. Nevertheless, the lack of standardization found among the guidelines makes any attempt to reduce or stop the drug very difficult for prescribers. Hyperbolic tapering by exponential dose reduction appears to be the most promising strategy for psychiatric drug discontinuation. Yet, we still face a constant challenge: how to safely obtain flexible doses for the discontinuation of drugs, particularly during the last steps in which lower doses are required. Further studies are needed to reduce the barriers associated with psychiatric drug discontinuation.

Abstract
RATIONALE The long-term effectiveness of olanzapine and aripiprazole in real clinical conditions at flexible doses in patients after hospital discharge has not been evaluated yet. OBJECTIVES This study was a multicenter retrospective cohort study. Patients with schizophrenia (n = 398) were prescribed olanzapine (n = 303) or aripiprazole (n = 95) at hospital discharge. The continuation of olanzapine or aripiprazole at 26, 52, or 104 weeks after the hospital discharge were compared using a Cox proportional hazards model and adjusted for possible confounders. RESULTS The Kaplan-Meier survival curves revealed that the continuation of olanzapine at 26 (P = 0.001) and 52 weeks (P = 0.018) was significantly higher than that of aripiprazole but not at 104 weeks. Olanzapine was better than aripiprazole in efficacy at 26 (hazard ratio: 0.321, 95% confidence interval: 0.159-0.645, P = 0.001), 52 (hazard ratio: 0.405, 95% confidence interval: 0.209-0.786, P = 0.008), and 104 weeks (hazard ratio: 0.438, 95% confidence interval: 0.246-0.780, P = 0.005). Aripiprazole was better than olanzapine in tolerability at 104 weeks (hazard ratio: 4.574, 95% confidence interval: 1.415-14.787, P = 0.011). Rates after two years continuation of olanzapine and aripiprazole were not significantly different in patients with less than five years' duration of illness, but olanzapine was more commonly maintained for more than two years in those patients who had been ill for over five years' due to its greater efficacy. CONCLUSION Olanzapine treatment showed better continuation rates at 26 and 52 after hospital discharge than aripiprazole, whereas maintenance with the two antipsychotics did not differ significantly at 104 weeks, due reduced tolerability of long-term olanzapine treatment.

Predicting psychotic relapse following randomised discontinuation of paliperidone in individuals with schizophrenia or schizoaffective disorder: an individual participant data analysis. Lancet Psychiatry 2023; 10:184-196. [PMID: 36804071 DOI: 10.1016/s2215-0366(23)00008-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/10/2022] [Revised: 12/09/2022] [Accepted: 12/20/2022] [Indexed: 02/17/2023]
Abstract
BACKGROUND Predicting relapse for individuals with psychotic disorders is not well established, especially after discontinuation of antipsychotic treatment. We aimed to identify general prognostic factors of relapse for all participants (irrespective of treatment continuation or discontinuation) and specific predictors of relapse for treatment discontinuation, using machine learning. METHODS For this individual participant data analysis, we searched the Yale University Open Data Access Project's database for placebo-controlled, randomised antipsychotic discontinuation trials with participants with schizophrenia or schizoaffective disorder (aged ≥18 years). We included studies in which participants were treated with any antipsychotic study drug and randomly assigned to continue the same antipsychotic drug or to discontinue it and receive placebo. We assessed 36 prespecified baseline variables at randomisation to predict time to relapse, using univariate and multivariate proportional hazard regression models (including multivariate treatment group by variable interactions) with machine learning to categorise the variables as general prognostic factors of relapse, specific predictors of relapse, or both. FINDINGS We identified 414 trials, of which five trials with 700 participants (304 [43%] women and 396 [57%] men) were eligible for the continuation group and 692 participants (292 [42%] women and 400 [58%] men) were eligible for the discontinuation group (median age 37 [IQR 28-47] years for continuation group and 38 [28-47] years for discontinuation group). Out of the 36 baseline variables, general prognostic factors of increased risk of relapse for all participants were drug-positive urine; paranoid, disorganised, and undifferentiated types of schizophrenia (lower risk for schizoaffective disorder); psychiatric and neurological adverse events; higher severity of akathisia (ie, difficulty or inability to sit still); antipsychotic discontinuation; lower social performance; younger age; lower glomerular filtration rate; benzodiazepine comedication (lower risk for anti-epileptic comedication). Out of the 36 baseline variables, predictors of increased risk specifically after antipsychotic discontinuation were increased prolactin concentration, higher number of hospitalisations, and smoking. Both prognostic factors and predictors with increased risk after discontinuation were oral antipsychotic treatment (lower risk for long-acting injectables), higher last dosage of the antipsychotic study drug, shorter duration of antipsychotic treatment, and higher score on the Clinical Global Impression (CGI) severity scale The predictive performance (concordance index) for participants who were not used to train the model was 0·707 (chance level is 0·5). INTERPRETATION Routinely available general prognostic factors of psychotic relapse and predictors specific for treatment discontinuation could be used to support personalised treatment. Abrupt discontinuation of higher dosages of oral antipsychotics, especially for individuals with recurring hospitalisations, higher scores on the CGI severity scale, and increased prolactin concentrations, should be avoided to reduce the risk of relapse.

Abstract
AIM This study aimed to examine symptom changes during short-term discontinuation of antipsychotics up to 3 weeks including the placebo washout phase in acute schizophrenia. METHODS The data from three double-blind, randomized, controlled trials comparing lurasidone versus placebo in patients with acute exacerbation of schizophrenia were analyzed. Symptom severity was assessed using the Positive and Negative Syndrome Scale (PANSS) total and the Clinical Global Impression-Severity scale (CGI-S) scores. The scores before and after the antipsychotic discontinuation phase were compared, and factors associated with score changes were explored. RESULTS Among 2154 patients participating in the trials, 600 who received antipsychotic monotherapy and completed the antipsychotic discontinuation phase were included in the analysis. No patients received clozapine. The mean duration of the discontinuation phase was 5.9 ± 2.5 days. The PANSS total and CGI-S scores significantly changed from 94.0 ± 9.5 to 95.4 ± 10.5 (P < 0.001) and from 4.9 ± 0.6 to 4.9 ± 0.7 (P = 0.041), respectively, during this phase; however, the absolute difference was minimal. The score changes were not associated with the type or dose of prior antipsychotics, or the duration or strategy (abrupt vs gradual) of antipsychotic discontinuation. CONCLUSIONS Symptoms may not worsen to a clinically meaningful degree after short-term discontinuation of non-clozapine antipsychotics up to 3 weeks in patients with acute exacerbation of schizophrenia, suggesting that antipsychotic efficacy persists at least several days after discontinuation. This finding supports once-daily dosing regimen of antipsychotics and abrupt antipsychotic discontinuation when switching to another antipsychotic.

Abstract
People with intellectual disabilities (PwID) are frequently prescribed long-term antipsychotics for behaviours that challenge (BtC) despite the lack of proven effectiveness and the increased risks for side effects of these medications in this population. National and international good clinical practice guidelines recommend deprescribing antipsychotics for BtC, which is often not successful due to environmental and other factors. The involvement of all stakeholders, including PwID, is crucial for deprescribing. However, studies showed that PwID and/or their families are often not involved in decision-making regarding the (de)prescribing of antipsychotics despite their desire to get involved. Moreover, studies on the views of PwID regarding their experiences of withdrawing from antipsychotics are lacking. The aim of this study was to gain insight into the views of PwID by investigating their experiences of discontinuation of long-term prescribed antipsychotics for BtC. A qualitative study was set up. Seven experts by experience with mild intellectual disabilities were interviewed. After six interviews, data saturation was achieved. Interviews were transcribed verbatim. Using phenomenological analysis, themes on lived experiences were extracted. Each consecutive interview was analysed. The four main themes extracted from the interviews were the quality of treatment, knowledge and information about psychotropics and the process of withdrawal, support from the participants' environment and the coping style of the interviewees themselves.

Abstract
OBJECTIVES Aripiprazole is an antipsychotic with a partial agonism of dopamine D2 and D3 receptors. This differential mechanism implies a rigorous appraisal of the appropriate therapeutic strategies in certain situations. To answer currently unsolved clinical questions about the use of oral and long-acting injectable (LAI) aripiprazole, we present here an expert consensus from 12 Spanish psychiatrists and a pharmacologist with extensive experience in the use of this antipsychotic. METHODS Through one face-to-face session and online collaboration, we reached consensus and established practical recommendations based on scientific evidence and clinical experience. We classified the available scientific literature according to SIGN system and attributed a level of evidence to each reviewed article. RESULTS The recommendations were divided according to (i) chronological dimension (based on previous treatments, including patients naïve or not to antipsychotic treatment and maintenance regimen), and (ii) dimension related to therapeutic options, comprising switches to aripiprazole and the most used combinations with this antipsychotic. CONCLUSIONS We recommend considering aripiprazole as first treatment option in the early stages of schizophrenia and in patients with affective symptoms and contemplating a switch to aripiprazole LAI in all candidate patients. Importantly, switches from other antipsychotics should consider previous antipsychotic history and exposure to aripiprazole. KEYPOINTSAripiprazole can be considered as first treatment option in early stages of schizophrenia and in patients with significant affective symptoms.Aripiprazole LAI shows better adherence than oral aripiprazole and could be considered in all candidate patients.Before switching to aripiprazole, detailed information about previous antipsychotic history should be gathered.Switch to aripiprazole should be managed differently for aripiprazole naïve and non-naïve patients.Rigorous and controlled studies on antipsychotics in real clinical practice should be carried out.

Assessment of Contributing Factors and Treatment Practices for Therapeutic Efficacy and Drug-Related Problems in Suicidal Psychotic Patients. Brain Sci 2022; 12:brainsci12050543.

Abstract
Suicide, a deliberate act of self-harm with the intention to die, is an emerging health concern but, unfortunately, the most under-researched subject in Pakistan, especially in Khyber Pukhtunkhwa (KPK). In this study, we aimed to identify risk factors that can be associated with suicidal behavior (SB) and to evaluate the prevailing treatment practices for therapeutic efficacy and drug-related problems (DRPs) in psychotic patients among the local population of KPK. A prospective, multicenter study was conducted for suicidal cases admitted to the study centers by randomized sampling. Socio-demographics and data on suicidal behavior were assessed using the Columbia-Suicide Severity Rating Scale (C-SSRS), socioeconomic condition by Kuppuswamy socioeconomic scale (KSES) and treatment adherence by Morisky Medication-Taking Adherence Scale (MMAS-4). Drug-related problems and the therapeutic efficacy of prevailing treatment practices were assessed at baseline and follow-up after 3 months of treatment provided. Regarding suicidality (N = 128), females reported more ideations (63.1%), while males witnessed more suicidal behavior (66.6%, p < 0.001). Suicide attempters were mostly married (55.6%, p < 0.002); highly educated (53.9%, p = 0.004); dissatisfied with their life and had a previous history (p < 0.5) of suicide attempt (SA) (20.6%), self-injurious behavior (SIB) (39.7%) and interrupted (IA) or aborted attempts (AA) (22.2%). A greater improvement was observed in patients receiving combination therapy (p = 0.001) than pharmacotherapy (p = 0.006) or psychotherapy (p = 0.183), alone. DRPs were also detected, including drug-selection problems (17.88%), dose-related problems (20.64%), potential drug−drug interactions (24.31%), adverse drug reactions (11.46%) and other problems like inadequate education and counseling (21.55%). Furthermore, it was also found that psychotic patients with suicidal ideations (SI) were significantly (p = 0.01) more adherent to the treatment as compared to those with suicidal attempts. We concluded that suicide attempters differed significantly from patients with suicidal ideations in psychotic patients and presented with peculiar characteristics regarding socio-demographic factors. A combination of therapies and adherence to the treatment provided better outcomes, and targeted interventions are warranted to address drug-related problems.

Abstract
BACKGROUND Antipsychotic medication can reduce psychotic symptoms and risk of relapse in people with schizophrenia and related disorders, but it is not always effective and adverse effects can be significant. We know little of patients' views about continuing or discontinuing antipsychotic treatment. AIMS To explore the views of people with schizophrenia and other psychotic disorders about continuing their antipsychotic medication or attempting to reduce or discontinue this medication with clinical support. METHODS We collected quantitative and qualitative data by conducting semi-structured interviews in London, UK. Factors predicting a desire to discontinue medication were explored. Content analysis of qualitative data was undertaken. RESULTS We interviewed 269 participants. 33% (95% CI, 27 to 39%) were content with taking long-term antipsychotic medication. Others reported they took it reluctantly (19%), accepted it on a temporary basis (24%) or actively disliked it (18%). 31% (95% CI, 25 to 37%) said they would like to try to stop medication with professional support, and 45% (95% CI, 39 to 51%) wanted the opportunity to reduce medication. People who wanted to discontinue had more negative attitudes towards the medication but were otherwise similar to other participants. Wanting to stop or reduce medication was motivated mainly by adverse effects and health concerns. Professional support was identified as potentially helpful to achieve reduction. CONCLUSIONS This large study reveals that patients are commonly unhappy about the idea of taking antipsychotics on a continuing or life-long basis. Professional support for people who want to try to reduce or stop medication is valued.

Adverse events after antipsychotic discontinuation: an individual participant data meta-analysis. Lancet Psychiatry 2022; 9:232-242. [PMID: 35183280 DOI: 10.1016/s2215-0366(22)00014-1] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/17/2021] [Revised: 12/05/2021] [Accepted: 12/20/2021] [Indexed: 01/20/2023]
Abstract
BACKGROUND Adverse events can occur after antipsychotic discontinuation but evidence from antipsychotic drug trials is scarce. We aimed to estimate the occurrence of adverse events after discontinuing antipsychotics. METHODS For this two-stage individual participant data meta-analysis, we searched the Yale University Open Data Access Project's database for randomised controlled trials of antipsychotics from database inception until May 6, 2021. We included placebo-controlled antipsychotic randomised controlled trials with individual participant data of participants (aged ≥ 18 years, of any sex and ethnicity) with schizophrenia, schizoaffective disorder, or bipolar disorder. Studies were excluded if treatment with antidepressants, lithium, or antiepileptic drugs was initiated as additive therapy at the start of the placebo phase. Starting from the screening or washout phase, we divided participants who were randomised to placebo into two groups: the discontinuation group (participants who discontinued prestudy antipsychotics at the start of the screening or washout phase) and control group (participants who did not take prestudy antipsychotics for at least 4 weeks before the start of the screening or washout phase). Participants were excluded from the discontinuation and control groups if they discontinued prestudy treatment with antidepressants, lithium, or antiepileptic drugs up to 4 weeks before baseline, received an antipsychotic as a tolerability test, or received a long-acting injection of an antipsychotic within 12 weeks before baseline. In the discontinuation group, individuals were excluded if they discontinued prestudy antipsychotic treatment more than 3 days before, or any day after, the start of screening or washout phase. The prespecified primary outcome was occurrence of at least one new somatic adverse event with an onset within 4 weeks after the start of the screening or washout phase. We implemented a generalised linear model that accounted for potential confounders, to estimate the effect of antipsychotic discontinuation. This study is registered with PROSPERO (CRD42021224350). FINDINGS We identified 409 records of which 18 were eligible and included in the analysis. From these 18 studies, 692 individuals (242 [35·0%] women and 450 [65·0%] men) were eligible for the discontinuation group and 935 individuals (339 [36·3%] women and 596 [63·7%] men) were eligible for the control group (median age in both groups: 39 years [IQR 30-47]). New somatic adverse events occurred in 295 (43%) individuals in the discontinuation group and 293 (31%) individuals in the control group (OR 1·74; 95% CI 1·27-2·39; τ2=0·15; moderate strength of evidence). New psychiatric adverse events were also more frequent in the discontinuation group than the control group (OR 2·01; 95% CI 1·38-2·94). Longer duration of treatment before discontinuation (OR for doubling the duration of treatment: 1·08; 95% CI 1·01-1·14) was associated with a higher probability of new somatic adverse events after antipsychotic discontinuation, and tapered discontinuation (compared with abrupt discontinuation: 0·54; 0·32-0·91) and no history of somatic illness (compared with history of somatic illness: 0·63; 0·43-0·91) were associated with lower probabilities of new somatic adverse events after antipsychotic discontinuation. The risk of bias was moderate in 13 (72·2%) studies and serious in five (27·8%) studies. INTERPRETATION We detected moderate evidence of emerging somatic adverse events after discontinuation of first-generation and second-generation antipsychotics, particularly after discontinuation of longer durations of treatment. Tapered discontinuation can mitigate the risk of emerging somatic adverse events after antipsychotic discontinuation. These findings have implications for the safety of treatment discontinuation and could be used for tailored treatment planning. FUNDING German Research Foundation.

Abstract
AIM There is an ongoing debate regarding the optimal timing of discontinuation of antipsychotic drugs for patients with first episode psychosis. Although most guidelines recommend maintenance therapy for at least 1 or 2 years after reaching remission, study results indicate that early discontinuation may be beneficial for at least a subsample of patients. To date, little is known about which medication strategies are applied in patients recovering from a first psychotic episode. In this study, we examined the beliefs and practices of clinicians on medication discontinuation. METHODS We performed a survey among 50 experienced Dutch psychiatrists to assess how often specific treatment strategies have been applied in the past 12 months, as well as their knowledge and expectations with respect to medication discontinuation. RESULTS Psychiatrists estimated that, after remission, they continued medication at the same dose for at least 12 months in 51.2% of cases, continued in a reduced dose in 33.8% of cases and discontinued medication in 9.1% of cases after 4.4 months of remission on average. Although the medication is discontinued in only a relatively small proportion of patients, almost half of all clinicians (45.9%) used this strategy at least once in the past 12 months. CONCLUSIONS There is substantial practice variation in antipsychotic medication strategies after remission from a first psychotic episode. Future research on long-term effects of early medication discontinuation can guide clinicians in making evidence-based decisions when treating first-episode patients.

Abstract
Hyperkinetic movement disorders are characterized by the presence of abnormal involuntary movements, comprising most notably dystonia, chorea, myoclonus, and tremor. Possible causes are numerous, including autoimmune disorders, infections of the central nervous system, metabolic disturbances, genetic diseases, drug-related causes and functional disorders, making the diagnostic process difficult for clinicians. Some diagnoses may be delayed without serious consequences, but diagnosis delays may prove detrimental in treatable disorders, ranging from functional disabilities, as in dopa-responsive dystonia, to death, as in Whipple's disease. In this review, we focus on treatable disorders that may present with prominent hyperkinetic movement disorders.

Abstract
INTRODUCTION Abrupt discontinuation of antipsychotics is associated with an increased risk of adverse events such as extrapyramidal symptoms in humans. In animal models, vacuous chewing movements may occur after antipsychotic discontinuation. We aim to assess vacuous chewing movements after the discontinuation of second-generation antipsychotics in animal models. METHODS PubMed, EMBASE, and Web of Science databases were searched for studies since inception until January 2, 2021. In addition, we manually searched references from included and relevant studies. Studies were included if a behavioral assessment of vacuous chewing movements (VCMs) in animal models was performed after discontinuation of a second-generation antipsychotic (SGA). Findings will be reviewed qualitatively and discussed with regard to clinical implications. RESULTS 5607 studies were screened and five studies were considered eligible for the qualitative analysis. The five studies reported results of behavioral assessments of VCMs after discontinuation of clozapine, olanzapine, and risperidone. VCMs were not reported to be increased after discontinuation of clozapine and olanzapine. However, VCMs were reported to be increased after discontinuation of higher but not lower dosages of risperidone. DISCUSSION These findings, based on a limited series of studies, suggest differences in the occurrence of extrapyramidal symptoms between second-generation antipsychotics. More research is needed to determine the magnitude of differences between antipsychotics and implications for clinical practice in humans.

Antipsychotics withdrawal in adults with intellectual disability and challenging behaviour: study protocol for a multicentre double-blind placebo-controlled randomised trial. BMC Psychiatry 2021; 21:439. [PMID: 34488701 PMCID: PMC8422779 DOI: 10.1186/s12888-021-03437-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/09/2021] [Accepted: 08/24/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND In people with intellectual disability (ID) and challenging behaviour, antipsychotics (AP) are often used off-label and for a long period. Despite a lack of evidence for efficacy for challenging behaviour and concerns about common and clinically relevant side effects, complete withdrawal often fails. We postulate three possible hypotheses for withdrawal failure: 1. Influence of subjective interpretation of behavioural symptoms by caregivers and family; 2. Beneficial effects from AP treatment on undiagnosed psychiatric illness, through improvement in sleep or a direct effect on behaviour; and 3. Misinterpretation of withdrawal symptoms as a recurrence of challenging behaviour. METHODS To investigate our hypotheses, we have designed a multicentre double-blind, placebo-controlled randomised trial in which AP (pipamperone or risperidone) are withdrawn. In the withdrawal group, the AP dose is reduced by 25% every 4 weeks and in the control group the dose remains unaltered. Behaviour, sleep, psychiatric disorders, withdrawal symptoms and side effects will be measured and compared between the two groups. If drop-out from the protocol is similar in both groups (non-inferiority), the first hypothesis will be supported. If drop-out is higher in the withdrawal group and an increase is seen in psychiatric disorders, sleep problems and/or behavioural problems compared to the control group, this suggests effectiveness of AP, and indications for AP use should be reconsidered. If drop-out is higher in the withdrawal group and withdrawal symptoms and side effects are more common in the withdrawal group compared to the control group, this supports the hypothesis that withdrawal symptoms contribute to withdrawal failure. DISCUSSION In order to develop AP withdrawal guidelines for people with ID, we need to understand why withdrawal of AP is not successful in the majority of people with ID and challenging behaviour. With this study, we will bridge the gap between the lack of available evidence on AP use and withdrawal on the one hand and the international policy drive to reduce prescription of AP in people with ID and challenging behaviour on the other hand. TRIAL REGISTRATION This trial is registered in the Netherlands Trial Register (NTR 7232) on October 6, 2018 ( www.trialregister.nl ).

Abstract
OBJECTIVE Withdrawal from psychoactive medication such as quetiapine is a well-documented phenomenon. Despite the extensive use of quetiapine, there have been few studies into the presence of discontinuation symptoms. We therefore performed a systematic review of published literature for evidence of quetiapine withdrawal or symptoms associated with discontinuation. METHODS We searched PubMed, Embase, CINAHL, Medline, Web of Science, PsycINFO for articles containing the terms 'Quetiapine' AND 'withdraw$' OR 'discontinue$'. We included all study types that reported on somatic withdrawal symptoms and had no language restrictions. We excluded studies where there was withdrawal from multiple medications or any other psychoactive substance, or where the only symptoms were psychological such as rebound psychosis or craving. RESULTS We included 13 papers, all of which were individual case reports. The quality of the individual case reports was sub-optimal, as assessed by the CARE Case Report Guidelines. There was an association between rapid cessation of quetiapine and onset of somatic symptoms such as nausea, vomiting, agitation, restlessness, diaphoresis, irritability, anxiety, dysphoria, sleep disturbance, insomnia, tachycardia, hypertension and dizziness. Three studies also reported the onset of a withdrawal dyskinesia characterised by abnormal choreiform movements as well as confusion and speech disturbance in some cases. However, these findings were limited by the number and quality of case reports identified. CONCLUSION Discontinuation symptoms are an uncommon side effect of quetiapine cessation, which may have clinical implications. Clinicians should therefore be alert to the possibility of quetiapine withdrawal in individuals who present with somatic symptoms or choreiform movements. However, large prospective studies are required to clarify this association.

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
AbstractMany critically ill patients suffer from delirium which is associated with significant morbidity and mortality. There is a paucity of data about the incidence, symptoms, or treatment of delirium in the pediatric intensive care unit (PICU). Risk factors for delirium are common in the PICU including central nervous system immaturity, developmental delay, mechanical ventilation, and use of anticholinergic agents, corticosteroids, vasopressors, opioids, or benzodiazepines. Hypoactive delirium is the most common subtype in pediatric patients; however, hyperactive delirium has also been reported. Various screening tools are validated in the pediatric population, with the Cornell Assessment of Pediatric Delirium (CAPD) applicable to the largest age range and able to detect signs and symptoms consistent with both hypo- and hyperactive delirium. Treatment of delirium should always include identification and reversal of the underlying etiology, reserving pharmacologic management for those patients without symptom resolution, or with significant impact to medical care. Atypical antipsychotics (olanzapine, quetiapine, and risperidone) should be used first-line in patients requiring pharmacologic treatment owing to their apparent efficacy and low incidence of reported adverse effects. The choice of atypical antipsychotic should be based on adverse effect profile, available dosage forms, and consideration of medication interactions. Intravenous haloperidol may be a potential treatment option in patients unable to tolerate oral medications and with significant symptoms. However, given the high incidence of serious adverse effects with intravenous haloperidol, routine use should be avoided. Dexmedetomidine should be used when sedation is needed and when clinically appropriate, given the positive impact on delirium. Additional well-designed trials assessing screening and treatment of PICU delirium are needed.

Abstract
Objective: Switching between second-generation antipsychotics (SGAs) is a common clinical practice in the treatment of schizophrenia and schizoaffective disorders due to differences in the drugs’ tolerability and safety profiles as well as the challenge of obtaining an ideal response. However, the factors associated with SGA switching remain uncertain and related real-world data are scarce. The main objective was to identify the factors associated with the switching of SGAs in patients with schizophrenia or schizoaffective disorder. Methods: We conducted a retrospective cohort study of outpatients with schizophrenia or schizoaffective disorder, who were aged ≥18 years and received a SGA (clozapine, olanzapine, risperidone, quetiapine or ziprasidone) from a Brazilian pharmaceutical assistance program for at least 3 months. We identified SGA users from 2008 to 2017 by using a national administrative database (Ambulatory Information System-SIA/SUS). The factors associated with the switches were evaluated by Cox proportional hazards regression and adjusted for sex and age; the confidence interval was set at 95% (95% CI). Results: In total, 563,765 patients were included. Female sex, advanced age of ≥70 years, residence in the Brazilian northeast region, and the type of antipsychotic used were associated with an increased risk of switching (p < 0.001). The incidence of switching ranged from 37.6/100 person-years for clozapine users to 58.2/100 person-years for risperidone users. Compared to the adjusted hazard ratio, for clozapine users, the corresponding ratios for risperidone, ziprasidone, quetiapine and olanzapine were 1.59 (95% CI, 1.57–1.61), 1.41 (95% CI, 1.39–1.44), 1.25 (95% CI, 1.23–1.26) and 1.11 (95% CI, 1.10–1.12) respectively. Conclusion: The groups most susceptible to SGA switching in real-life setting were older individuals, women, and those living in the Brazilian northeast region. Risperidone was associated with the highest risk of switching and as expected, clozapine was associated with the lowest risk of switching than that associated with the other SGAs.

Abstract
The process of stopping antipsychotics may be causally related to relapse, potentially linked to neuroadaptations that persist after cessation, including dopaminergic hypersensitivity. Therefore, the risk of relapse on cessation of antipsychotics may be minimized by more gradual tapering. There is converging evidence that suggests that adaptations to antipsychotic exposure can persist for months or years after stopping the medication-from animal studies, observation of tardive dyskinesia in patients, and the clustering of relapses in this time period after the cessation of antipsychotics. Furthermore, PET imaging demonstrates a hyperbolic relationship between doses of antipsychotic and D2 receptor blockade. We, therefore, suggest that when antipsychotics are reduced, it should be done gradually (over months or years) and in a hyperbolic manner (to reduce D2 blockade "evenly"): ie, reducing by one quarter (or one half) of the most recent dose of antipsychotic, equivalent approximately to a reduction of 5 (or 10) percentage points of its D2 blockade, sequentially (so that reductions become smaller and smaller in size as total dose decreases), at intervals of 3-6 months, titrated to individual tolerance. Some patients may prefer to taper at 10% or less of their most recent dose each month. This process might allow underlying adaptations time to resolve, possibly reducing the risk of relapse on discontinuation. Final doses before complete cessation may need to be as small as 1/40th a therapeutic dose to prevent a large decrease in D2 blockade when stopped. This proposal should be tested in randomized controlled trials.

Abstract
Dementia affects about 47 million people worldwide, number expected to exponentially increase within 30 years. Alzheimer’s disease (AD) is the most common dementia type, accounting on its own for almost 70% of all dementia cases. Behavioral and psychological symptoms (BPSD) frequently occur during the disease progression; to treat agitation, aggressiveness, delusions and hallucinations, the use of antipsychotic drugs should be limited, due to their safety issues. In this literature review regarding the use of antipsychotics for treating BPSD in dementia, the advantages and limitation of antipsychotic drugs have been evaluated. The available medications for the management of behavioral and psychological symptoms are the antipsychotics, classed into typical and atypical, depending on their action on dopamine and serotonin receptors. First generation, or typical, antipsychotics exhibit lack of tolerability and display a broad range of side effects such as sedation, anticholinergic effects and extrapyramidal symptoms. Atypical, or second generation, antipsychotics bind more selectively to dopamine receptors and simultaneously block serotonin receptors, resulting in higher tolerability. High attention should be paid to the management of therapy interruption or switch between antipsychotics, to limit the possible rebound effect. Several switching strategies may be adopted, and clinicians should “tailor” therapies, accounting for patients’ symptoms, comorbidities, polytherapies and frailty.

Abstract
Most guidelines recommend long-term, indefinite neuroleptic (or antipsychotic) treatment for people with schizophrenia, recurrent psychosis or bipolar disorder, on the basis that these medications reduce the chance of relapse. However, neuroleptics have significant adverse effects, including sexual dysfunction, emotional blunting, metabolic disturbance and brain shrinkage, and patients often request to stop them. Evidence for the benefits of long-term treatment is also not as robust as generally thought. Short-term randomised trials show higher rates of relapse among those whose neuroleptic treatment is discontinued compared with those on maintenance treatment, but they are confounded by adverse effects associated with the withdrawal of established medication. Some longer-term studies show possible advantages of medication reduction and discontinuation in terms of improved social functioning and recovery. Therefore, there is a good rationale for supporting patients who wish to stop their medication, especially given the patient choice agenda favoured by The National Institute for Clinical Excellence (NICE). The major barrier to stopping antipsychotics is an understandable fear of relapse among patients, their families and clinicians. Institutional structures also prioritise short-term stability over possible long-term improvements. The risk of relapse may be mitigated by more gradual reduction of medication, but further research is needed on this. Psychosocial support for patients during the process of reducing medication may also be useful, particularly to enhance coping skills. Guidelines to summarise evidence on ways to reduce medication would be useful. Many patients want to try and stop neuroleptic medication for good reasons, and psychiatrists can help to make this a realistic option by supporting people to do it as safely as possible, with the best chance of a positive outcome.

Abstract
OBJECTIVE Avoiding withdrawal symptoms following antipsychotic discontinuation is an important factor when planning a safe therapy. We performed a systematic review and meta-analysis concerning occurrence of withdrawal symptoms after discontinuation of antipsychotics. DATA SOURCES We searched the databases CENTRAL, Pubmed, and EMBASE with no restriction to the beginning of the searched time period and until October 1, 2019 (PROSPERO registration no. CRD42019119148). STUDY SELECTION Of the 18,043 screened studies, controlled and cohort trials that assessed withdrawal symptoms after discontinuation of oral antipsychotics were included in the random-effects model. Studies that did not implement placebo substitution were excluded from analyses. The primary outcome was the proportion of individuals with withdrawal symptoms after antipsychotic discontinuation. We compared a control group with continued antipsychotic treatment in the assessment of odds ratio and number needed to harm (NNH). DATA EXTRACTION We followed guidelines by the Cochrane Collaboration, PRISMA, and MOOSE. RESULTS Five studies with a total of 261 individuals were included. The primary outcome, proportion of individuals with withdrawal symptoms after antipsychotic discontinuation, was 0.53 (95% CI, 0.37-0.70; I2 = 82.98%, P < 0.01). An odds ratio of 7.97 (95% CI, 2.39-26.58; I2 = 82.7%, P = 0.003) and NNH of 3 was calculated for the occurrence of withdrawal symptoms after antipsychotic discontinuation. CONCLUSION Withdrawal symptoms appear to occur frequently after abrupt discontinuation of an oral antipsychotic. The lack of randomized controlled trials with low risk of bias on antipsychotic withdrawal symptoms highlights the need for further research.

Abstract
OBJECTIVES To describe the antipsychotics, route of administration, dosage regimen, and outcomes reported to prevent or treat delirium in hospitalized children. METHODS Medline, Embase, and International Pharmaceutical Abstracts were searched using the keywords "haloperidol," "olanzapine," "quetiapine," "risperidone," "ziprasidone," and "delirium." Articles evaluating the use of these agents to manage delirium in hospitalized children that were published between 1946 and August 2019 were included. Two authors independently screened each article for inclusion. Reports were excluded if they were published abstracts or included fewer than 3 patients in the report. RESULTS Thirteen reports that included 370 children receiving haloperidol, quetiapine, olanzapine, and/or risperidone for delirium treatment were reviewed. Most children received haloperidol (n = 131) or olanzapine (n = 125). Significant variability in dosing was noted. A total of 23 patients (6.2%) had an adverse drug event, including 13 (56.5%) who experienced dystonia and 3 (13.0%) with a prolonged corrected QT interval. Most reports described improvement in delirium symptoms; however, only 5 reports used a validated screening tool for PICU delirium to evaluate antipsychotic response. CONCLUSIONS Most reports noted efficacy with antipsychotics, but these reports were limited by sample size and lacked a validated PICU delirium tool. Future research is needed to determine the optimal agent and dosage regimen to treat PICU delirium.

Abstract
RATIONALE Changing antipsychotics of patients with chronic schizophrenia involves several risks. Switching to aripiprazole is especially difficult. We investigated switching methods and related factors for successful switching patients with chronic schizophrenia to aripiprazole. OBJECTIVES This study was a multi-center historical cohort study and approved by the research ethics committee of Okayama University Hospital and Okayama Psychiatric Medical Center. We compared survival proportions of 178 chronic schizophrenia patients who continued aripiprazole monotherapy for 6 months after non-direct switching (add-on switching (n = 45), cross switching (n = 62)) or direct switching (n = 71). We adjusted possible confounders using a Cox proportional hazards model. RESULTS Of patients with chronic schizophrenia, 56.7% (101/178) were switched to aripiprazole monotherapy, and 55.0% (98/178) showed improvement in symptoms as demonstrated by the Clinical Global Impression Severity score. Kaplan-Meier survival curves showed that non-direct switching had a higher survival proportion than direct switching (log-rank test, p = 0.012). Even after adjusting for several variables using a Cox proportional hazards model, add-on switching had a significantly lower hazard at 6 months than direct switching (hazard ratio 0.42, 95% confidence interval 0.21-0.82, P = 0.01). In cases of switching to aripiprazole for psychiatric symptoms, non-direct switching had a lower hazard than direct switching (hazard ratio 0.41, 95% confidence interval 0.21-0.81, P = 0.01) but was not significant for adverse reaction. When aripiprazole was switched from olanzapine, add-on switch showed the lowest hazard ratio for continuation (hazard ratio 0.29, 95% confidence interval 0.07-1.11, P = 0.07). CONCLUSIONS Flexibility in strategies when switching to aripiprazole may induce a better outcome for patients with chronic schizophrenia.

Brexpiprazole has a low risk of dopamine D 2 receptor sensitization and inhibits rebound phenomena related to D 2 and serotonin 5-HT 2A receptors in rats. Neuropsychopharmacol Rep 2019; 39:279-288. [PMID: 31487433 PMCID: PMC7292306 DOI: 10.1002/npr2.12076] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2019] [Revised: 07/24/2019] [Accepted: 08/02/2019] [Indexed: 12/21/2022] Open
Abstract
Background Long‐term antipsychotic treatment in patients with schizophrenia can induce supersensitivity psychosis and tardive dyskinesia which is thought to be caused by dopamine D2 receptor sensitization. We evaluated the effects of brexpiprazole on D2 receptor sensitivity after subchronic treatment in rats. We also evaluated whether brexpiprazole could suppress enhanced response to D2 receptors in rats subchronically dosed with another atypical antipsychotic. Methods The maximum D2 receptor density (Bmax) and apomorphine (a D2 receptor agonist)‐induced stereotypy were measured in rats orally dosed with vehicle, haloperidol (1 mg/kg), or brexpiprazole (4 or 30 mg/kg for Bmax, 6 or 30 mg/kg for stereotypy) for 21 days. Then, effects of oral administrations of brexpiprazole (3 mg/kg), aripiprazole (10 mg/kg), and olanzapine (3 mg/kg) against increases in apomorphine‐induced hyperlocomotion and (±)‐2,5‐dimethoxy‐4‐iodoamphetamine hydrochloride (DOI: a 5‐HT2A receptor agonist)‐induced head twitches were evaluated in rats subcutaneously treated with risperidone (1.5 mg/kg/d) via minipumps for 21 days. Results Haloperidol and brexpiprazole (30 mg/kg: approximately tenfold ED50 of anti‐apomorphine‐induced stereotypy) but not brexpiprazole (4 or 6 mg/kg) significantly increased the Bmax and apomorphine‐induced stereotypy. Brexpiprazole (3 mg/kg) and olanzapine (3 mg/kg) significantly suppressed both increases in apomorphine‐induced hyperlocomotion and also DOI‐induced head twitches in rats subchronically treated with risperidone, but aripiprazole (10 mg/kg) significantly suppressed only apomorphine‐induced hyperlocomotion. Conclusion Brexpiprazole has a low risk of D2 receptor sensitization after a repeated administration and suppresses the rebound phenomena related to D2 and 5‐HT2A receptors after a repeated administration of risperidone. Brexpiprazole has less potential to evoke dopamine D2 receptor supersensitivity in rats after repeated administration compared to haloperidol. In addition, brexpiprazole may have a lower risk for producing rebound symptoms associated with D2 receptor, 5‐HT2A receptor sensitization when switching from other antipsychotics such as risperidone.![]()

Switching Antipsychotics to Blonanserin in Patients with Schizophrenia: An Open-label, Prospective, Multicenter Study. CLINICAL PSYCHOPHARMACOLOGY AND NEUROSCIENCE 2019; 17:423-431. [PMID: 31352709 PMCID: PMC6705098 DOI: 10.9758/cpn.2019.17.3.423] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/23/2018] [Revised: 10/25/2018] [Accepted: 10/26/2018] [Indexed: 12/26/2022]
Abstract
Objective This study was performed to investigate the efficacy and tolerability of blonanserin in schizophrenic patients who were previously treated with other antipsychotics but, due to insufficient response, were switched to blonanserin. Methods A total of 52 patients with schizophrenia who were unresponsive to treatment with antipsychotic monotherapy or combination therapy were recruited into this 12-week, open-label, prospective, multicenter study. Patients were switched to blonanserin from their existing antipsychotics over a maximum 2-week tapering-off period. Efficacy was primarily evaluated using the 18-item Brief Psychiatric Rating Scale (BPRS). Assessments were performed at baseline, and at weeks 1, 2, 4, 8, and 12. Results Switching to blonanserin resulted in a significant decrease in the mean total score on the BPRS from baseline (56.8 ± 9.4) to week 12 (42.1 ± 13.8, p < 0.001). The most common adverse events were extrapyramidal symptoms (n = 12, 23.1%), insomnia (n = 10, 19.2%), and emotional arousal (n = 6, 11.5%). Overweight or obese patients (body mass index ≥ 23 kg/m2, n = 33) who switched to blonanserin exhibited significant weight loss from 75.2 ± 9.3 kg at baseline to 73.5 ± 9.2 kg at week 12 (p = 0.006). The total cholesterol (baseline, 236.1 ± 47.6 mg/dl; endpoint [week 12], 209.9 ± 28.0 mg/dl; p = 0.005) and prolactin levels (baseline, 80.0 ± 85.2 ng/ml; endpoint [week 12], 63.2 ± 88.9 ng/ml; p = 0.003) were also significantly improved in patients with hypercholesterolemia or hyperprolactinemia. Conclusion The results of the present study suggest that switching to blonanserin may be an effective strategy for schizophrenic patients unresponsive to other antipsychotic treatments.

Switching to antipsychotic monotherapy vs. staying on antipsychotic polypharmacy in schizophrenia: A systematic review and meta-analysis. Schizophr Res 2019; 209:50-57. [PMID: 31182319 DOI: 10.1016/j.schres.2019.05.030] [Citation(s) in RCA: 22] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/02/2019] [Revised: 05/18/2019] [Accepted: 05/20/2019] [Indexed: 12/21/2022]
Abstract
BACKGROUND While recent meta-analyses have reported the superiority of antipsychotic polypharmacy (APP) over antipsychotic monotherapy (APM) in schizophrenia, switching to APM can be beneficial in terms of side effects. To determine whether patients receiving APP should switch to APM or stay on APP, we conducted a systematic review and meta-analysis. METHODS Randomized controlled trials (RCTs) examining a switch from APP to APM vs. staying on APP were systematically selected from a previous meta-analysis comparing APP with APM in patients with schizophrenia. In addition, we conducted an updated systematic literature search using MEDLINE, Embase, and Cochrane Central Register of Controlled Trials. Data on study discontinuation, relapse, psychopathology, neurocognition, extrapyramidal symptoms, and body weight/body mass index (BMI) were extracted and synthesized. RESULTS A total of 6 RCTs involving 341 patients were included. All studies examined a switch from 2 antipsychotic agents to a single agent. Clozapine-treated patients were included in 3 studies. There was a significant difference in study discontinuation due to all causes in favor of staying on APP (N = 6, n = 341, RR = 2.28, 95% CI = 1.50-3.46, P < 0.001). There were no significant differences in relapse, any psychopathology, neurocognition, extrapyramidal symptoms, or body weight/BMI between the 2 groups. The quality of evidence was low to very low. CONCLUSIONS The findings suggest that clinicians should closely monitor patient condition when switching to APM after receiving 2 antipsychotics. Given the low to very low overall quality of the evidence, the findings should be considered preliminary and inconclusive.

Abstract
OBJECTIVE To investigate the influence of adherence to psychotropic medications upon the risk of completed suicide by comparing person-level prescriptions and postmortem toxicological findings among complete-suicide cases and non-suicide controls in Sweden 2006-2013. METHODS Using national registries with full coverage on dispensed prescriptions, results of medico-legal autopsies, causes of death, and diagnoses from inpatient care, estimated continuous drug use for 30 commonly prescribed psychotropic medications was compared with forensic-toxicological findings. Subjects who had died by suicide (cases) were matched (1:2) with subjects who had died of other causes (controls) for age, sex, and year of death. Odds ratios were calculated using logistic regression to estimate the risk of completed suicide conferred by partial adherence and non-adherence to pharmacotherapy. Adjustments were made for previous inpatient care and the ratio of initiated and discontinued dispensed prescriptions, a measure of the continued need of treatment preceding death. RESULTS In 5294 suicide cases and 9879 non-suicide controls, after adjusting for the dispensation ratio and other covariates, partial adherence and non-adherence to antipsychotics were associated with 6.7-fold and 12.4-fold risks of completed suicide, respectively, whereas corresponding risk estimates for antidepressant treatment were not statistically significant and corresponding risk increases for incomplete adherence to antidepressant treatment were lower (1.6-fold and 1.5-fold, respectively) and lacked statistical significance. CONCLUSION After adjustment for the need of treatment, biochemically verified incomplete adherence to antipsychotic pharmacotherapy was associated with markedly increased risks of completed suicide.

A structured programme to withdraw antipsychotics among adults with intellectual disabilities: The Cornwall experience. JOURNAL OF APPLIED RESEARCH IN INTELLECTUAL DISABILITIES 2019; 32:1389-1400.

Abstract
BACKGROUND Antipsychotic medications are used among 19%-58% of adults with intellectual disabilities to manage challenging behaviour against the NICE guideline recommendations. Studies show that it is possible to completely withdraw antipsychotics in about one third of adults with intellectual disabilities and a dose reduction of 50% or more in another third. METHOD In Cornwall, over three years the present authors developed a structured pathway to withdraw antipsychotics among adults with intellectual disabilities which involved people with intellectual disabilities and their carers, GPs, community learning disability team members and pharmacists. RESULTS The present authors managed to withdraw antipsychotics totally among 46.5% (33/71) and reduced over 50% of dosage in another 11.3% (8/71) of adults with intellectual disabilities. At three months follow-up no one required hospital admission or change in placement. CONCLUSION It is possible to withdraw/reduce antipsychotics in a high proportion of adults with intellectual disabilities if a concerted effort is made involving all stakeholders from the outset.

Abstract
BACKGROUND AND OBJECTIVE Methods and justifications for discontinuing psychotropic drugs in randomized controlled trials (RCTs), and RCTs' acknowledgement of possible withdrawal symptoms following discontinuation, have not been examined systematically, which this review aims to do. Study Eligibility, Data Extraction, and Synthesis: Publications in MEDLINE, EMBASE, and PsycINFO (2000-2017) randomly assigning participants diagnosed with mental disorders to discontinue antipsychotic, antidepressant, anticonvulsant, antimanic, mood-stabilizing, benzodiazepine, or stimulant drugs. Authors independently extracted data, devised a typology of trials, and assessed trials' recognition of with-drawal symptoms. RESULTS Eighty RCTs (70% with industry participation) discontinued drugs from 5,757 participants to investigate relapse prevention (44%), successful dis-continuation (26%), architecture of withdrawal (14%), and practicality of discontinuation (10%). RCTs of stimulants, antidepressants, and antipsychotics mostly aimed to reach conclusions about relapse prevention by testing abrupt or rapid discontinuations; RCTs of benzodiazepines mostly aimed to reduce drug use by testing longer-lasting, supportive discontinuations. In 67% of RCTs, no justification was given for the specific discontinuation strategy, which lasted under 2 weeks in 60% of RCTs. Possible withdrawal confounding of trial outcomes was addressed in 14% of eligible RCTs. LIMITATIONS Only the published literature was searched. CONCLUSIONS AND IMPLICATIONS RCTs use drug discontinuation to study several key issues in psychopharmacology but infrequently justify how they implement it or acknowledge that possible withdrawal symptoms may threaten internal validity. Reappraising the use of drug discontinuation and the recognition of withdrawal symptoms in RCTs is required.

Abstract
OBJECTIVES: Switching between different antipsychotic therapies is a frequent occurrence in the management of patients with schizophrenia and other psychotic disorders. This paper provides a review of the principles of antipsychotic switching and discusses pharmacological principles underlying adverse events that occur while switching olanzapine to another antipsychotic medication. It offers suggestions for management of switch-associated adverse events in clinical settings. CONCLUSIONS: Few publications explore olanzapine switch-related adverse events, the underlying pharmacological principles and appropriate switching strategies to minimise the risk of adverse events. There is still a need for further studies to verify existing knowledge and assist in the development of 'gold standard' guidelines that outline appropriate switching strategies and duration of the switching process to reduce and avoid adverse events.

Guidance for switching from off-label antipsychotics to pimavanserin for Parkinson's disease psychosis: an expert consensus. CNS Spectr 2018; 23:402-413.

Abstract
Patients with Parkinson's disease psychosis (PDP) are often treated with an atypical antipsychotic, especially quetiapine or clozapine, but side effects, lack of sufficient efficacy, or both may motivate a switch to pimavanserin, the first medication approved for management of PDP. How best to implement a switch to pimavanserin has not been clear, as there are no controlled trials or case series in the literature to provide guidance. An abrupt switch may interrupt partially effective treatment or potentially trigger rebound effects from antipsychotic withdrawal, whereas cross-taper involves potential drug interactions. A panel of experts drew from published data, their experience treating PDP, lessons from switching antipsychotic drugs in other populations, and the pharmacology of the relevant drugs, to establish consensus recommendations. The panel concluded that patients with PDP can be safely and effectively switched from atypical antipsychotics used off label in PDP to the recently approved pimavanserin by considering each agent's pharmacokinetics and pharmacodynamics, receptor interactions, and the clinical reason for switching (efficacy or adverse events). Final recommendations are that such a switch should aim to maintain adequate 5-HT2A antagonism during the switch, thus providing a stable transition so that efficacy is maintained. Specifically, the consensus recommendation is to add pimavanserin at the full recommended daily dose (34 mg) for 2-6 weeks in most patients before beginning to taper and discontinue quetiapine or clozapine over several days to weeks. Further details are provided for this recommendation, as well as for special clinical circumstances where switching may need to proceed more rapidly.

Abstract
BACKGROUND Akathisia is a common and distressing neuropsychiatric syndrome associated with antipsychotic medication, characterised by subjective and objective psychomotor restlessness. The goal of this guideline is to provide clinicians with recommendations on the assessment and treatment of akathisia. METHODS We performed a systematic review of therapeutic studies assessing the treatment of antipsychotic-induced extrapyramidal symptoms. Forty studies on akathisia and 4 systematic reviews evaluating the adverse effects of antipsychotics were used in the formulation of recommendations. Studies were rated for methodological quality using the American Academy of Neurology Risk of Bias Classification system. The overall level of evidence classifications and grades of recommendation were made using the Scottish Intercollegiate Guidelines Network framework. RESULTS As a good practice point, clinicians should systematically assess akathisia with a validated scale before starting antipsychotics and during antipsychotic dosage titration. For the management of akathisia, there was adequate evidence to allow recommendations regarding antipsychotic dose reduction, antipsychotic polypharmacy, switching antipsychotic medication, and the use of adjuvant medications including beta-blockers, anticholinergics, 5HT2A antagonists, benzodiazepines, and vitamin B6. CONCLUSION The treatment of antipsychotic-induced akathisia should be personalised, with consideration of antipsychotic dose reduction, cessation of antipsychotic polypharmacy, and switching to an antipsychotic with a perceived lower liability for akathisia, before the use of adjuvant medications. The choice of adjuvant medications should favour the more established treatments, with careful consideration of contraindications and side effects. Limitations in the evidence should be acknowledged and prompt cautious prescribing, particularly with respect to the duration of use of adjuvant medications, is warranted.

Abstract
We present a case of domperidone withdrawal in a woman using the medication as a galactagogue. Our primary goal is to increase the literature available to providers who work with women who are breastfeeding. We evaluated a woman presenting to our reproductive psychiatry clinic for consultation regarding anxiety and agitation in the context of domperidone discontinuation. We evaluated the available literature regarding domperidone as a galactagogue, as well as the literature regarding adverse effects. The patient presented with withdrawal symptoms after gradual taper and discontinuation of domperidone. After restarting the medication, her symptoms resolved. She was able to successfully discontinue domperidone with a slow, gradual taper. Domperidone is occasionally used as a galactagogue in women with inadequate milk supply. We report a case in which a woman experienced withdrawal symptoms after domperidone discontinuation.

Abstract
Psychiatric comorbidities affect a large percentage of people with epilepsy and have a detrimental impact on their quality of life. Recently, behavioural comorbidities, with similar characteristics to human psychiatric diseases, have been identified in dogs with idiopathic epilepsy. In particular, behaviours motivated by the fear-anxiety emotional system have been found to be associated with the occurrence of idiopathic epilepsy in both dogs receiving anti-epileptic drugs, and drug-naïve dogs. There has been little research into the relationship between epilepsy and behavioural signs, and even less into potential treatment protocols. The following article will review available literature from human medicine to describe the current state of knowledge about the bi-directional relationship between anxiety and epilepsy, draw parallels from reported anxiogenic and anxiolytic properties of anti-epileptic drugs and attempt to provide pharmaceutical and behavioural guidance for veterinary patients with epilepsy and comorbid anxiety.

Regularity of self-reported daily dosage of mood stabilizers and antipsychotics in patients with bipolar disorder. Int J Bipolar Disord 2018; 6:10. [PMID: 29713845 PMCID: PMC6161976 DOI: 10.1186/s40345-018-0118-8] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/08/2017] [Accepted: 01/16/2018] [Indexed: 12/23/2022] Open
Abstract
BACKGROUND Polypharmacy is often prescribed for bipolar disorder, yet medication non-adherence remains a serious problem. This study investigated the regularity in the daily dosage taken of mood stabilizers and second generation antipsychotics. METHODS Daily self-reported data on medications taken and mood were available from 241 patients with a diagnosis of bipolar disorder who received treatment as usual. Patients who took the same mood stabilizer or second generation antipsychotic for ≥ 100 days were included. Approximate entropy was used to determine serial regularity in daily dosage taken. Generalized estimating equations were used to estimate if demographic or clinical variables were associated with regularity. RESULTS There were 422 analysis periods available from the 241 patients. Patients took drugs on 84.4% of days. Considerable irregularity was found, mostly due to single-day omissions and dosage changes. Drug holidays (missing 3 or more consecutive days) were found in 35.8% of the analysis periods. Irregularity was associated with an increasing total number of psychotropic drugs taken (p = 0.009), the pill burden (p = 0.026), and the percent of days depressed (p = 0.049). CONCLUSION Despite low missing percent of days, daily drug dosage may be irregular primarily due to single day omissions and dosage changes. Drug holidays are common. Physicians should expect to see partial adherence in clinical practice, especially with complex drug regimens. Daily dosage irregularity may impact the continuity of drug action, contribute to individual variation in treatment response, and needs further study.

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
Recently, a range of prescription and over-the-counter drugs have been reportedly used as Novel Psychoactive Substances (NPS), due to their potential for abuse resulting from their high dosage/idiosyncratic methods of self-administration. This paper provides a systematic review of the topic, focusing on a range of medications which have emerged as being used recreationally, either on their own or in combination with NPS. Among gabapentinoids, pregabalin may present with higher addictive liability levels than gabapentin, with pregabalin being mostly identified in the context of opioid, polydrug intake. For antidepressants, their dopaminergic, stimulant-like, bupropion activities may explain their recreational value and diversion from the therapeutic intended use. In some vulnerable clients, a high dosage of venlafaxine (‘baby ecstasy’) is ingested for recreational purposes, whilst the occurrence of a clinically-relevant withdrawal syndrome may be a significant issue for all venlafaxine-treated patients. Considering second generation antipsychotics, olanzapine appears to be ingested at very large dosages as an ‘ideal trip terminator’, whilst the immediate-release quetiapine formulation may possess proper abuse liability levels. Within the image- and performance- enhancing drugs (IPEDs) group, the beta-2 agonist clenbuterol (‘size zero pill’) is reported to be self-administered for aggressive slimming purposes. Finally, high/very high dosage ingestion of the antidiarrhoeal loperamide has shown recent increasing levels of popularity due to its central recreational, anti-withdrawal, opiatergic effects. The emerging abuse of prescription drugs within the context of a rapidly modifying drug scenario represents a challenge for psychiatry, public health and drug-control policies.

Abstract
Most drugs that act on the central nervous system (CNS) require dose titration to avoid withdrawal syndrome. Tizanidine withdrawal syndrome is caused by adrenergic discharge due to its α2-agonist mechanism and is characterized by hypertension, reflex tachycardia, hypertonicity, and anxiety. Although tizanidine withdrawal syndrome is mentioned as a potential side effect of cessation, it is not common and there have been few reports. We present the case of a 31-year-old woman with tizanidine withdrawal syndrome after discontinuing medication prescribed for a muscle contracture (tizanidine). She showed high adrenergic activity with nausea, vomiting, generalized tremor, dysthermia, hypertension, and tachycardia. Symptoms were reversed and successful reweaning was achieved by restarting tizanidine followed by slow downward titration. Withdrawal syndrome should be considered when drugs targeting the CNS are suddenly stopped. Weaning regimens should be closely monitored for acute withdrawal reactions.

Is There a Potential of Misuse for Quetiapine?: Literature Review and Analysis of the European Medicines Agency/European Medicines Agency Adverse Drug Reactions' Database.

Abstract
PURPOSE/BACKGROUND A recent years' increase in both prescribing and availability of second-generation antipsychotics (SGAs) has been observed. According to the literature, typically made up by case studies/series, quetiapine seems to be the most commonly misused SGA, with both intranasal and intravenous intake modalities having been described. Another SGA that has been anecdotally reported to be misused is olanzapine. For these molecules, both a previous history of drug misuse and being an inmate have been described as factors associated with misuse. Hence, while providing here an updated literature review of the topic, we aimed at assessing all cases of quetiapine misuse/abuse/dependence/withdrawal as reported to the European Medicines Agency's EudraVigilance (EV) database; this was carried out in comparison with the reference drug olanzapine. METHODS All spontaneous, European Medicines Agency database reports relating to both quetiapine (2005-2016) and olanzapine (2004-2016) misuse/abuse/dependence/withdrawal issues were retrieved, and a descriptive analysis was performed. RESULTS From the EV database, 18,112 (8.64% of 209,571) and 4178 (7.58% of 55,100) adverse drug reaction reports of misuse/abuse/dependence/withdrawal were associated with quetiapine and olanzapine, respectively. The resulting proportional reporting ratio values suggested that the misuse/abuse-, dependence-, and withdrawal-related adverse drug reactions were more frequently reported for quetiapine (1.07, 1.01, and 5.25, respectively) in comparison with olanzapine. CONCLUSIONS Despite data collection limitations, present EV data may suggest that, at least in comparison with olanzapine, quetiapine misuse may be a cause for concern.
