It has been stated that some antipsychotic drugs might cause genotoxic and carcinogenic effects. Ziprasidone (ZIP) is commonly used an antipsychotic drug. However, its genotoxicity and carcinogenicity data are very limited. The cytotoxicity and genotoxicity of ZIP on human peripheral blood lymphocytes were examined in vitro by sister chromatid exchange (SCE), chromosome aberration (CA) and micronucleus (MN) tests in this study. Lymphocyte cultures were treated with 50, 75 and 100 μg/ml of ZIP in the presence and absence of a metabolic activator (S9 mix)...

BACKGROUND: Health services often manage agitated or violent people, and such behaviour is particularly prevalent in emergency psychiatric services (10%). The drugs used in such situations should ensure that the person becomes calm swiftly and safely. OBJECTIVES: To examine whether haloperidol plus promethazine is an effective treatment for psychosis-induced aggression. SEARCH METHODS: On 6 May 2015 we searched the Cochrane Schizophrenia Group's Register of Trials, which is compiled by systematic searches of major resources (including MEDLINE, EMBASE, AMED, BIOSIS, CINAHL, PsycINFO, PubMed, and registries of clinical trials) and their monthly updates, handsearches, grey literature, and conference proceedings...

RATIONALE: We have previously demonstrated that treatment with ziprasidone and aripiprazole selectively inhibit the development of behavioral sensitization to cocaine in mice. We now investigate their effects on a counter-conditioning strategy in mice and the importance of the treatment environment for this phenomenon. OBJECTIVE: Evaluate the context-specificity of ziprasidone and aripiprazole on conditioned locomotion to cocaine and cocaine-induced hyperlocomotion and behavioral sensitization in a counter-conditioning strategy in mice...

PURPOSE: The emergence of electronic prescribing devices with clinical decision support systems (CDSS) is able to significantly improve management pharmacological treatments. We developed a web application available on smartphones in order to help clinicians monitor prescription and further propose CDSS. METHOD: A web application (www.MEmind.net) was developed to assess patients and collect data regarding gender, age, diagnosis and treatment. We analyzed antipsychotic prescriptions in 4345 patients attended in five Psychiatric Community Mental Health Centers from June 2014 to October 2014...

Consensus guidelines which are applicable in New Zealand and worldwide recommend that the duration of exposure to antipsychotics not exceed 12 weeks, unless justified for mental illnesses like schizophrenia and severe psychotic symptoms which require longer treatment. There has been limited information on time-to-first discontinuation (TTFD) for second-generation antipsychotics (SGAs) in a real world population setting in older people. The study objective was to compare TTFD, adherence, and persistence for individual SGA new users among people 65 years and older...

Obsessive compulsive disorder (OCD) is characterized by recurrent, unwanted thoughts (obsessions) and/or repetitive behaviors (compulsions). Although selective serotonin reuptake inhibitors are widely used to treat OCD, only half of the patients respond well. Several potentiation strategies including off-label use of antipsychotics (mostly risperidone, quetiapine) have been tried. Ziprasidone is an atypical antipsychotic with the best affinity ratio of 5 HT 2A/D2 and 5HT2C/D2 receptors. There is a limited data on ziprasidone in pediatric groups...

Postpartum psychosis (PP) is a severe psychiatric disorder affecting a small proportion of new mothers shortly after childbirth. The molecular pathophysiology underlying the disorder is currently poorly understood, and there are no amenable animal models for the condition; maternal deficiency for the enzyme steroid sulfatase has been proposed as a potential risk mechanism. Here we show that inhibition of steroid sulfatase with 667-COUMATE (10mg/kg p.o.) in new mouse mothers results in behavioural abnormalities that can be partially alleviated by the administration of the clinically-efficacious antipsychotic ziprasidone (0...

Modern antipsychotic drugs are employed increasingly in the treatment of mood disorders as well as psychoses, stimulating interest in their possible contributions to altering suicidal risk. Clozapine remains the only treatment with an FDA-recognized indication for reducing suicidal risk (in schizophrenia). We carried out a systematic, computerized search for reports of studies involving antipsychotic drug treatment and suicidal behaviors. A total of 19 reports provide data with preliminary support for potential suicide risk-reducing effects of olanzapine, quetiapine, ziprasidone, aripiprazole, and asenapine in addition to clozapine, and provide some support for antipsychotic drug treatment in general...

Migraine headache is among the most prevalent neurologic disorders. Status migrainosus often leads to hospitalization, and multiple medications are sometimes required for symptomatic relief. In 2008, neurologists at our institution started using the atypical antipsychotic ziprasidone as an abortive medication for status migrainosus. The Clinical Investigation Data Exploration Repository was used to search for patients admitted to the Barnes-Jewish Hospital inpatient neurology service with diagnoses of "headache" or "migraine...

Sleep disturbances predominantly take the form of insomnia in patients with unipolar disorder, while patients with bipolar disorder show a decreased need for sleep. Sleep impairment in these patients is a risk factor for the development of a major depressive episode and suicidal behavior. Administration of second-generation antipsychotics (SGAs) olanzapine, quetiapine, and ziprasidone as augmentation therapy or monotherapy to unipolar and bipolar disorder patients, respectively, has been shown to improve sleep continuity and sleep architecture...

The use of atypical antipsychotic drugs (APD) was reported to be associated with adverse effects on the kidneys. Thus, the aim of this study was to examine whether APD exerted their adverse effects by interfering with the renal antioxidant defense system. Male 3-mo-old Wistar rats were treated for 28 d with ziprasidone (ZIP), clozapine (CLO), or sertindole (SER) using a daily dose recommended for antipsychotic drug therapy. The expression and activities of antioxidant enzymes superoxide dismutase (SOD) type 1 and type 2, catalase (CAT), glutathione reductase (GR), and glutathione S-transferases (GSTs) activity were measured in the kidneys...

RATIONALE: Patients with schizophrenia spectrum disorders have increased morbidity and mortality, largely due to cardiovascular disease, which is associated with antipsychotic treatment. OBJECTIVES: Because of the link between cardiometabolic risk, non-alcoholic fatty liver disease (NAFLD), and antipsychotics, we aimed to investigate the development of NAFLD during the first 3 years of antipsychotic treatment in first episode non-affective psychosis patients. RESULTS: A sample of 191 subjects was included in final analyses, randomly assigned to aripiprazole (N = 83), risperidone (N = 12), quetiapine (N = 46), and ziprasidone (N = 50)...

Intravenous haloperidol has been associated with torsades de pointes (TdP). These two sudden deaths were probable adverse drug reactions (ADRs) following intramuscular (IM) antipsychotics. The autopsies described lack of heart pathology and were highly compatible with the possibility of TdP in the absence of risk factors other than the accumulation of antipsychotics with a high serum peak after the last injection, leading to death within hours. The first case was a 27-year-old African-American male with schizophrenia but no medical issues...

BACKGROUND: At present, no tools exist to estimate objectively the risk of poor treatment outcomes in patients with first-episode psychosis. Such tools could improve treatment by informing clinical decision-making before the commencement of treatment. We tested whether such a tool could be successfully built and validated using routinely available, patient-reportable information. METHODS: By applying machine learning to data from 334 patients in the European First Episode Schizophrenia Trial (EUFEST; International Clinical Trials Registry Platform number, ISRCTN68736636), we developed a tool to predict poor versus good treatment outcome (Global Assessment of Functioning [GAF] score ≥65 vs GAF <65, respectively) after 4 weeks and 52 weeks of treatment...

Implementing the most suitable treatment strategies and making appropriate clinical decisions about individuals with a first episode of psychosis (FEP) is a complex and crucial task, with relevant impact in illness outcome. Treatment approaches in the early stages should go beyond choosing the right antipsychotic drug and should also address tractable factors influencing the risk of relapse. Effectiveness and likely metabolic and endocrine disturbances differ among second-generation antipsychotics (SGAs) and should guide the choice of the first-line treatment...

Over the past decades, several adjunctive therapies have been introduced for treatment-resistant depression (TRD), and these strategies have ebbed and flowed in popularity. Currently, adjunctive therapy with the second-generation antipsychotics (SGAs) is most commonly used by psychiatrists. Four SGAs are FDA approved for indications related to TRD (aripiprazole, brexpiprazole, olanzapine, and quetiapine extended release); some evidence also supports use of risperidone and ziprasidone as adjunctive therapies...
