Neuroleptic malignant syndrome (NMS) is a rare but potentially fatal adverse event associated with the use of antipsychotics. Although atypical antipsychotics were initially considered to carry no risk of NMS, reports have accumulated over time implicating them in NMS causation. Almost all atypical antipsychotics have been reported to be associated with NMS. The clinical profile of NMS caused by certain atypical antipsychotics such as clozapine has been reported to be considerably different from the NMS produced by typical antipsychotics, with diaphoresis encountered more commonly, and rigidity and tremor encountered less frequently...

BACKGROUND: Second generation antipsychotic medications (SGAs) are widely used by reproductive-age women to treat a number of psychiatric illnesses. Some SGAs have been associated with an increased risk of developing diabetes, although information regarding their diabetogenic effect in pregnant women is scarce. OBJECTIVE: To evaluate the risk of gestational diabetes (GDM) among women treated with SGA. METHOD: The Massachusetts General Hospital (MGH) National Pregnancy Registry for Atypical Antipsychotics (NPRAA) collects data on drug use, pregnancy outcomes, and other characteristics from pregnant women, ages 18-45 years, using 3 phone interviews conducted at (1) enrollment during pregnancy, (2) 7 months' gestation, and (3) 2-3 months postpartum...

OBJECTIVES: To quantify how adherence mismeasurement affects the estimated impact of adherence on inpatient costs among patients with serious mental illness (SMI). STUDY DESIGN: Proportion of days covered (PDC) is a common claims-based measure of medication adherence. Because PDC does not measure medication ingestion, however, it may inaccurately measure adherence. We derived a formula to correct the bias that occurs in adherence-utilization studies resulting from errors in claims-based measures of adherence...

The methionine-folate cycle-dependent one-carbon metabolism is implicated in the pathophysiology of schizophrenia. Since schizophrenia is a developmental disorder, we examined the effects that perturbation of the one-carbon metabolism during gestation has on mice progeny. Pregnant mice were administered methionine equivalent to double their daily intake during the last week of gestation. Their progeny (MET mice) exhibited schizophrenia-like social deficits, cognitive impairments and elevated stereotypy, decreased neurogenesis and synaptic plasticity, and abnormally reduced local excitatory synaptic connections in CA1 neurons...

AIM: Compare medication utilization, costs and healthcare resource use in schizophrenia patients with substance-related disorders initiated on once-monthly paliperidone palmitate (PP1M) or an oral atypical antipsychotic (OAA). MATERIALS & METHODS: Data from six Medicaid states (07/2009-03/2015) were used to compare outcomes between PP1M and OAA patients. RESULTS: PP1M patients had higher 12-month antipsychotic adherence and persistence than OAA patients...

Drug-induced Extrapyramidal Symptoms Scale (DIEPSS) is developed in the era of second-generation antipsychotics and is suitable for evaluation of the low incidence of extrapyramidal symptoms occurring in the treatment of atypical antipsychotics, as well as the relationship between personal and social functioning. The study was carried out at the Institute of Mental Health in Serbia in 2015 Study used the 127 DIEPSS video clips material, recorded from 1987 till 2015. Four raters performed the assessment simultaneously, individually rating one assigned item immediately after seeing the video clip...

Tourette syndrome (TS) is a common neuropsychiatric disorder, more common in males than females, with onset before age 18. TS is characterized by multiple motor tics and one or more vocal/phonic tics, persisting for more than a year. Tics are unvoluntary, abrupt, rapid, repetitive, but non-rhythmic movements or sounds (vocalizations). They are preceded by an inner urge. Tics can be temporarily suppressed, but this leads to a powerful re-emergence. The performance of tics results in immediate but transient relief...

Atypical antipsychotics such as olanzapine often induce excessive weight gain and type 2 diabetes. However, the mechanisms underlying these drug-induced metabolic perturbations remain poorly understood. Here, we used an experimental model that reproduces olanzapine-induced hyperphagia and obesity in female C57BL/6 mice. We found that olanzapine treatment acutely increased food intake, impaired glucose tolerance, and altered physical activity and energy expenditure in mice. Furthermore, olanzapine-induced hyperphagia and weight gain were blunted in mice lacking the serotonin 2C receptor (HTR2C)...

RATIONALE: Rodents exposed prenatally to valproic acid (VPA) exhibit autism spectrum disorder (ASD)-like behavioral abnormalities. We recently found that prenatal VPA exposure causes hypofunction of the prefrontal dopaminergic system in mice. This suggests that the dopaminergic system may be a potential pharmacological target for treatment of behavioral abnormalities in ASD patients. OBJECTIVES: In the present study, we examined the effects of antipsychotic drugs, which affect the dopaminergic system, on the social interaction deficits, recognition memory impairment, and reduction in dendritic spine density in the VPA mouse model of ASD...

BACKGROUND: This is an update of the original Cochrane Review, last published in 2012 (Loy 2012). Children and youths with disruptive behaviour disorders may present to health services, where they may be treated with atypical antipsychotics. There is increasing usage of atypical antipsychotics in the treatment of disruptive behaviour disorders. OBJECTIVES: To evaluate the effect and safety of atypical antipsychotics, compared to placebo, for treating disruptive behaviour disorders in children and youths...

Quetiapine, an atypical antipsychotic, has been extensively used in patients with bipolar disorder. Overdose of quetiapine can result in severe complications, such as coma, seizure, respiratory depression, arrhythmia, and even death. However, the paucity of toxicological evaluation in adolescence causes more potential risks in this population. Herein, we present a case of hypotension and convulsive syncope after exposure to a small dose of quetiapine in a 16-year-old who was diagnosed with bipolar disorder...

Tardive dyskinesia (TD) is a potentially disabling condition encompassing all delayed, persistent, and often irreversible abnormal involuntary movements arising in a fraction of subjects during long-term exposure to centrally acting dopamine receptor-blocking agents such as antipsychotic drugs and metoclopramide. However, the pathogenesis of TD has proved complex and remains elusive. To investigate the mechanism underlying the development of TD, we have chronically exposed 17 Cebus apella monkeys to typical (11) or atypical (6) antipsychotic drugs...

INTRODUCTION: Little is known about the frequency and nature of medication errors (MEs) and adverse drug events (ADEs) that occur in mental health hospitals. OBJECTIVES: This systematic review aims to provide an up-to-date and critical appraisal of the epidemiology and nature of MEs and ADEs in this setting. METHOD: Ten electronic databases were searched, including MEDLINE, Embase, CINAHL, International Pharmaceutical Abstracts, PsycINFO, Scopus, British Nursing Index, ASSIA, Web of Science, and Cochrane Database of Systematic Reviews (1999 to October 2016)...

In the present study, a series of tetrahydropyridopyrimidinone derivatives, possessing potent dopamine D2, serotonin 5-HT1A and 5-HT2A receptors properties, was synthesized and evaluated as potential antipsychotics. Among them, 3-(2-(4-(benzo[b]thiophen-4-yl)piperazin-1-yl)ethyl)-9-hydroxy-2-methyl-6,7,8,9-tetrahydro-4H-pyrido[1,2-a]pyrimidin-4-one (10d) held the best pharmacological profile. It not only exhibited potent and balanced activities for D2, 5-HT1A, and 5-HT2A receptors, but was also endowed with low activities for α1A, 5-HT2C, H1 receptors and hERG channels, suggesting a low propensity for inducing orthostatic hypotension, weight gain and QT prolongation...
