Histamine H3 receptors are present as autoreceptors on histaminergic neurons and as heteroreceptors on nonhistaminergic neurones. They control the release and synthesis of histamine and several other key neurotransmitters in the brain. H3 antagonism may be a novel approach to develop a new class of antipsychotic medications given the gathering evidence reporting therapeutic efficacy in several central nervous system disorders. Several medications such as cariprazine, lurasidone, LY214002, bexarotene, rasagiline, raloxifene, BL-1020 and ITI-070 are being developed to treat the negative symptoms and cognitive impairments of schizophrenia...

Lurasidone hydrochloride, a benzisothiazol derivative, is a second-generation (atypical) antipsychotic agent that has received regulatory approval for the treatment of schizophrenia in the US, Canada, the EU, Switzerland, and Australia, and also for bipolar depression in the US and Canada. In addition to its principal antagonist activity at dopamine D2 and serotonin 5-HT2A receptors, lurasidone has distinctive 5-HT7 antagonistic activity, and displays partial agonism at 5-HT1A receptors, as well as modest antagonism at noradrenergic α2A and α2C receptors...

The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) mixed features specifier provides a less restrictive definition of mixed mood states, compared to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR), including mood episodes that manifest with subthreshold symptoms of the opposite mood state. A limited number of studies have assessed the efficacy of treatments specifically for DSM-5-defined mixed features in mood disorders. As such, there is currently an inadequate amount of data to appropriately inform evidence-based treatment guidelines of DSM-5 defined mixed features...

When treating persons with schizophrenia, delaying time to relapse is a main goal. Antipsychotic medication has been the primary treatment approach, and there are a variety of different choices available. Lurasidone is a second-generation (atypical) antipsychotic agent that is approved for the treatment of schizophrenia and bipolar depression. Three long-term studies of lurasidone have examined time to relapse in persons with schizophrenia, including a classic placebo-controlled randomized withdrawal study and two 12-month active comparator studies (vs risperidone and vs quetiapine extended-release)...

OBJECTIVE: To assess the effect of dose increase in adult patients with schizophrenia who demonstrate inadequate initial response to standard-dose lurasidone and to evaluate the efficacy of low-dose lurasidone in adult patients with schizophrenia. METHODS: In this randomized, double-blind, placebo-controlled study conducted between May 2013 and June 2014, hospitalized patients with acute schizophrenia (DSM-IV-TR criteria) were randomly assigned to double-blind treatment with lurasidone 20 mg/d (n = 101), lurasidone 80 mg/d (n = 199), or placebo (n = 112)...

Somnolence is a common side effect of antipsychotics. To assess the incidence of this side effect, we performed a MEDLINE search for randomized, double-blinded, placebo- or active-controlled studies of adult patients treated with antipsychotics for schizophrenia, mania, bipolar depression, or bipolar disorder. We extracted rates of somnolence from original publications and pooled them based on the dose of each antipsychotic in the same psychiatric condition, then estimated the absolute risk increase (ARI) and the number needed to harm (NNH) of an antipsychotic relative to placebo or an active comparator in the same psychiatric condition...

INTRODUCTION: The atypical antipsychotic (APs) drugs have become the most widely used agents to treat a variety of psychoses because of their superiority with regard to safety and tolerability profile compared to conventional/'typical' APs. AREAS COVERED: We aimed at providing a synthesis of most current evidence about the safety and tolerability profile of the most clinically used atypical APs so far marketed. Qualitative synthesis followed an electronic search made inquiring of the following databases: MEDLINE, Embase, PsycINFO and the Cochrane Library from inception until January 2016, combining free terms and MESH headings for the topics of psychiatric disorders and all atypical APs as following: ((safety OR adverse events OR side effects) AND (aripiprazole OR asenapine OR quetiapine OR olanzapine OR risperidone OR paliperidone OR ziprasidone OR lurasidone OR clozapine OR amisulpride OR iloperidone))...

The cytochrome P450 isoform that is primarily involved in the metabolism of the antipsychotic lurasidone is CYP3A4. Drugs that inhibit or induce this enzyme would then be expected to increase or decrease serum concentrations of lurasidone, respectively. Atazanavir, an HIV-1 protease inhibitor, has demonstrated to be an inhibitor of CYP3A4 and would be expected to increase the exposure of any drug metabolized by this enzyme. We report a case of an atazanavir precipitated drug-drug interaction that led to elevated serum concentrations of lurasidone and associated clinical symptoms of drug toxicity...

Insomnia is a common feature in schizophrenia, and is characterized by an increase of sleep latency (SL), as well as reductions in total sleep time (TST) and sleep efficiency (SE). Regarding sleep architecture, non-rapid-eye-movement (NREM) sleep, slow wave sleep (SWS) and rapid-eye-movement (REM) sleep latency are decreased, whereas REM sleep tends to remain unchanged. According to polysomnographic studies, clozapine, olanzapine, quetiapine and ziprasidone administration increased TST and/or SE in healthy subjects...

In the majority of cases of bipolar disorder, manic episodes are usually brief and typically responsive to currently available psychopharmacological agents. In contrast, depressive manifestations are more prevalent and persistent, and can present as major depressive/mixed episodes or residual interepisode symptoms. The depressive phase is often associated with other neuropsychiatric conditions, such as anxiety spectrum disorders, substance use disorders, stressor-related disorders, and eating disorders. It is viewed as a systemic disease with associated ailments such as metabolic syndrome, diabetes mellitus, and cardiovascular disease...

BACKGROUND: Long-term improvement of health-related quality of life (HRQoL) in schizophrenia may improve adherence and reduce relapse and rehospitalization. This analysis examines long-term changes in HRQoL among patients with schizophrenia switched to lurasidone from other antipsychotics. METHODS: Patients who completed an open-label 6-week switch study continued on lurasidone for an additional 24-weeks. HRQoL was measured using the self-reported Personal Evaluation of Transitions in Treatment (PETiT) scale and Short-Form 12 (SF-12) questionnaire...

BACKGROUND: Depressive symptoms associated with bipolar disorder negatively impact health-related quality of life (HRQoL). The efficacy of lurasidone in reducing depressive symptoms has been previously demonstrated. The objective of this study was to examine the direct and indirect effect (mediated through improvement in depression symptoms) of lurasidone in improving patient HRQoL. METHODS: A secondary analysis of data was conducted of two 6-week, double-blind, placebo-controlled trials assessing the effect of lurasidone (lurasidone monotherapy [20-60 mg/day or 80-120 mg/day]; lurasidone adjunctive to lithium or valproate [20-120 mg/day]) in patients with bipolar depression...

The aim of this paper was to review the up-to-date evidence base on pharmacology and clinical properties of lurasidone. Lurasidone is an atypical antipsychotic, approved by the US Food and Drug Administration (FDA) for the treatment of schizophrenia and bipolar depression. Lurasidone exhibits both an antipsychotic and antidepressant action. Based on its pharmacodynamics profile, it is believed that the drug's clinical action is mediated mainly through the D2, 5-HT2A and 5-HT7 receptors inhibition. In patients with schizophrenia the recommended dose range is 40-80mg/day...

BACKGROUND: Lurasidone, an atypical antipsychotic, is a potent 5-HT7 antagonist and D2 , 5-HT2A antagonist, and 5-HT1A partial agonist. As such, lurasidone would be expected to modulate sleep and circadian function but there have been no human studies of the sleep effects of a 5-HT7 antagonist. The purpose of this study was to assess effects of lurasidone on sleep. METHODS: This was a cross-over, polysomnographic study involving 54 healthy volunteers who underwent two treatment periods (order randomized) each consisting of two nights in the laboratory: Night 1-lights out at usual bedtime; Night 2-4-h advance of sleep phase and randomization to either lurasidone 40 mg or placebo...

In this study, designed to evaluate the efficacy of lurasidone as adjunctive therapy with lithium or valproate, patients with bipolar I depression were randomized to 6 weeks of double-blind treatment with lurasidone (N = 180) or placebo (N = 176), added to background treatment with lithium or valproate. All patients were treated with lithium or valproate for a minimum of 4 weeks prior to screening. This was confirmed either by prospective treatment after study enrolment (run-in cohort), or retrospectively, with blood levels of lithium and valproate at screening (non-run-in cohort)...

Bipolar affective disorder is a debilitating illness that manifests as cyclical episodes of mood elevation and depression, but the treatment of the depressive episodes (i.e., bipolar depression) differs considerably from the treatment of major depressive disorder. In bipolar affective disorder, it is well known that patients spend a significantly greater amount of time in depressive episodes than manic or hypomanic episodes, yet there are currently just three Food and Drug Administration-approved agents for the treatment of bipolar depression: (1) olanzapine/fluoxetine combination (2) quetiapine, both immediate- and extended-release, and (3) lurasidone...
