Active clinical trials for "Psychotic Disorders"

We evaluate the efficacy and tolerability of duloxetine in the treatment of major depressive episodes during the course of psychotic disorders

It is hypothesized that the atypical antipsychotic, Seroquel, will cause significant reduction in drug and alcohol cravings in patients with schizophrenia and comorbid cocaine and/methamphetamine dependence compared to the atypical antipsychotic, risperidone (Risperdal). Patients treated with Seroquel will have less use of cocaine and/or methamphetamine as measured by the Time Line Follow-back, over a 24-week follow-up period.

This is a 9 week, multicentre, randomized, double-blind, placebo-controlled trial with two parallel groups. There is also an open-label extension phase of 18 weeks. Both medications to be used in the study, clozapine and risperidone, are fully approved for the treatment of schizophrenia.

The purpose of this study is to prove safety and efficacy of aripiprazole.

The purpose of this study is to determine whether the administration of omega-3 polyunsaturated fatty acids, particularly eicosapentaenoic acid (EPA), can be useful both to reduce coronary artery disease (CAD) risk and illness severity in clinically-stable patients with schizophrenia (or schizoaffective disorder), major depression or bipolar disorder (depressed phase) being treated with lipid lowering drugs (e.g., statins).

The purpose of this clinical research study is to assess the safety and tolerability of aripiprazole in patients with psychosis associated with Parkinson's disease.

The purposes of this study are to assess the efficacy, safety, and side effects among doses approved by the Food and Drug Administration and higher (not FDA approved) doses of olanzapine in patients with schizophrenia or schizoaffective disorder.

This study will determine the effectiveness of combining selective serotonin reuptake inhibitors (SSRIs) with antipsychotic medications in the treatment of psychotic depression.

The purpose of this study is to learn if aripiprazole is effective in the treatment of a large number of persons diagnosed with schizophrenia or schizoaffective disorders

The primary objective is to compare effectiveness of ziprasidone treatment to current treatments (haloperidol, olanzapine or risperidone) measured by change in Brief Psychiatric Rating Scale (BPRS) scores versus baseline
