Epidemiologic data on treatment resistant depression (TRD) in Asia-Pacific countries are limited. We estimated the incidence of TRD in Taiwan using a cohort of 704,265 adults randomly sampled from Taiwan's National Health Insurance Research database for 2005. TRD was defined as a patient having pharmaceutically treated depression (PTD) not adequately responding to 2 antidepressant (AD) regimens, i.e., AD regimens that were followed by other AD regimens. Among 2751 PTD subjects, 576 (20.94%, 95% CI: 19.46, 22...

Chlorpromazine is a low potency "typical" antipsychotic agent used to treat schizophrenia. It continues to be prescribed frequently in India owing to its lower cost. There have been previous reports of ocular adverse effects with prolonged use of chlorpromazine. We report three patients who developed corneal and lenticular opacities secondary to prolonged chlorpromazine use leading to visual impairment. Early detection of ocular deposits and switching over to risperidone from chlorpromazine helped in the reversal of chlorpromazine- induced ocular side effects in one of them...

Paliperidone palmitate 3-month formulation (PP3M), a long-acting injectable atypical antipsychotic, was recently approved in the US and Europe for the treatment of schizophrenia in adult patients who have already been treated with paliperidone palmitate 1-month formulation (PP1M) for ≥4 months. This article reviews the pharmacokinetic rationale for the approved dosing regimens for PP3M, dosing windows, management of missed doses and treatment discontinuation, switching to other formulations, and dosing in special populations...

To address whether wait discontinuation (i.e., introducing the new antipsychotic while maintaining the first for a period before initiating its discontinuation) is superior to non-wait discontinuation (i.e., initiating the first antipsychotic's discontinuation when introducing the new antipsychotic) in antipsychotic switching, we conducted a meta-analysis of randomized controlled trials comparing gradual vs. wait-and-gradual antipsychotic discontinuation in patients with schizophrenia. The meta-analysis of 5 studies (n=410) demonstrated no significant differences in any clinical outcomes, including study discontinuation, psychopathology, extrapyramidal symptoms, and treatment-emergent adverse events, between the two groups...

Hyperprolactinemia is an underappreciated/unknown adverse effects of antipyschotics. The consequences of hyperprolactinemia compromise therapeutic adherence and can be serious. We present the consensus recommendations made by a group of experts regarding the management of antipsychotic-induced hyperprolactinemia. The current consensus was developed in 3 phases: 1, review of the scientific literature; 2, subsequent round table discussion to attempt to reach a consensus among the experts; and 3, review by all of the authors of the final conclusions until reaching a complete consensus...

The study aims to identify prescribing and switching patterns of antipsychotics in clinical practice. A 16-month, prospective study was conducted at the Psychiatric Hospital Idrija, Slovenia. Inpatients (N = 311) with schizophrenia spectrum disorders were observed. The causes for switching antipsychotics and switching strategies were analyzed. Analyzing a total of 3954 prescriptions, the collected data confirmed that treatment strategies in this psychiatric hospital are very complex. It was found that 37 percent of inpatients had at least one switch...

Ather Muneer
Many bipolar disorder patients exhibit mixed affective states, which portend a generally more severe illness course and treatment resistance. In the previous renditions of Diagnostic and Statistical Manual mixed states were narrowly defined in the context of bipolar I disorder, but with the advent of DSM-5 the term "mixed episode" was dropped and replaced by "mixed features" specifier which could be broadly applied to manic, hypomanic and depressive episodes in both the bipolar spectrum and major depressive disorders...

Bipolar disorder (BD) is associated with periodic symptom exacerbations, leading to functional impairment, and increased risk of suicide. Although clozapine has never been approved for the treatment of BD, it is occasionally used in severe mania. The aim of the study is to evaluate the risks and benefits of switching clozapine in remitted BD patients. This is an observational, mirror image study of 62 consecutive remitted BD outpatients treated with clozapine. Twenty-five patients were switched to another antipsychotic following a change in a drug reimbursement rule, while 37 continued on clozapine...

OBJECTIVE: This open-label prospective study investigated the effects of paliperidone extended release (ER) on hostility in Thai patients with schizophrenia. BACKGROUND: Patients diagnosed with schizophrenia may be hostile or exhibit aggressive behavior, which can occasion their admission to psychiatric hospital. Antipsychotic medications are often used to treat hostility and aggression in such patients. Paliperidone ER is effective and well tolerated in the treatment of schizophrenia...

BACKGROUND: In March 2015, pipotiazine palmitate depot antipsychotic was globally withdrawn due to the shortage of its active ingredient. Thus, all patients receiving this medication had to be switched to an alternative antipsychotic drug. In this study we set to evaluate the process of switching away from pipotiazine palmitate within our clinical service, and its impact on hospitalization. METHODS: Demographic and clinical data on patients who were receiving pipotiazine palmitate in Northamptonshire at the time of its withdrawal were anonymously extracted from their electronic records and analyzed using descriptive statistics...

Tardive dyskinesias (TD) are serious, often irreversible side effects of dopamine blocking agents, most commonly first-generation antipsychotics. No definitive treatment exists, with different interventions showing inconsistent results. We report a case of TD presenting after 12 years of olanzapine therapy in a 66-year-old Hispanic male with paranoid schizophrenia. The TD symptoms were successfully treated within a few weeks by switching to clozapine. Two cases of olanzapine-induced TD treated with clozapine have previously been reported, but in those cases, the symptom onset was quicker, ranging from a few months to a few years after initiation of olanzapine therapy, and the treatment response was relatively slower...

Antipsychotic polypharmacy (APP) is commonplace despite lacking evidence of its effectiveness. We aimed to identify psychiatrists' rationale for and attitudes towards APP and to determine if attitudes influence antipsychotic polypharmacy prescription rates in a survey of a nationally representative sample of Nigerian psychiatrists (of which a majority were senior trainees: 74.2%). Prescriber characteristics, practices and attitudes were compared in 'high' (>30%) vs. 'low' (≤30%) antipsychotic polypharmacy prescribers and results were adjusted for multiple comparisons...

People with severe mental illness (SMI) have reduced life expectancy compared with the general population, which can be explained partly by their increased risk of diabetes. We conducted a meta-analysis to determine the clinical effectiveness of pharmacological and non-pharmacological interventions for improving glycaemic control in people with SMI (PROSPERO registration: CRD42015015558). A systematic literature search was performed on 30/10/2015 to identify randomised controlled trials (RCTs) in adults with SMI, with or without a diagnosis of diabetes that measured fasting blood glucose or glycated haemoglobin (HbA1c)...

BACKGROUND: Antipsychotic switching is routine in clinical practice, although it remains unclear which is the preferable switching method: immediate discontinuation of the current antipsychotic or a gradual tapering approach. The first strategy has been implicated in rebound/withdrawal symptoms and emergence/exacerbation of symptoms, whereas the gradual approach is thought to pose a risk of additive or synergistic side effects if employed in the context of a crossover approach. METHODS: MEDLINE, Embase, and Cochrane Central Register of Controlled Trials were systematically searched...

INTRODUCTION: Schizophrenia is a chronic and debilitating mental disorder that affects the patient's and their family's quality of life, as well as financial costs and health care settings. Despite the variety of available antipsychotics, optimal treatment outcomes are not always achieved. Novel drugs, such as iloperidone, can provide more effective, tolerable and safer strategies. AIM: To review the evidence for the clinical impact of iloperidone on the treatment of patients with schizophrenia...

OBJECTIVE: Methamphetamine (MA) use has recently been associated with high levels of psychiatric hospitalization and serious social dysfunction. MA use causes frequent psychotic symptoms, which can be treated with antipsychotics. However, people with intellectual disabilities (ID) are vulnerable to adverse effects resulting from treatment with antipsychotic medications. METHOD: We report two cases of MA-induced psychosis (MAP) in patients with ID who were treated with the antipsychotic blonanserin...
