Active clinical trials for "Schizophrenia"

Tardive dyskinesia is a common complication of conventional antipsychotic treatment in subjects with schizophrenia. This study investigates whether the addition of the omega-3 fatty acid, ethyl-eicosapentaenoic acid (EPA) to usual treatment improves movement disorder in 84 schizophrenia subjects with established tardive dyskinesia. The initial double-blinded, randomised trial duration is 12 weeks, followed by further 46 weeks of open-label treatment.

The purpose of this trial is to assess the safety, tolerability and pharmacokinetics of aripiprazole tablets following oral administration to children and adolescents.

The primary objective of this study is to evaluate the amelioration of the sleep architecture of patients with schizophrenia and schizophrenia-related insomnia, treated with either 9 mg of extended-release paliperidone ER or placebo, using polysomnography.

The study hypothesis is that 3-2,4 dimethoxybenzylidene anabaseine (DMXB-A), an orally administered nicotinic cholinergic agonist, will improve attention and other neuropsychological dysfunctions in schizophrenia, leading to improved psychosocial outcome.

The purpose of this study is to: Evaluate the efficacy and safety of the new antipsychotics, quetiapine (300-500mg/day) and risperidone (3-4mg/day) compared to each other and to fluphenazine (10-15mg/day), a high potency typical antipsychotic in patients who meet the DSM IV criteria for schizophrenia. To evaluate the efficacy and safety of quetiapine (1200mg/day) in patients who have not responded to conventional and newer antipsychotics. To evaluate the effectiveness of quetiapine (300-500mg/day), and risperidone (3-5mg/day) compared to each other and fluphenazine (10-15mg/day) in the treatment of hostility and aggression in treatment-resistant schizophrenic patients. To evaluate the effectiveness of quetiapine (300-500mg/day) and risperidone (3-5mg/day) compared to each other and fluphenazine (10-15mg/day) on rates of discharge, quality of life, and independent living skills. To assess prolactin levels and to evaluate any relationship with sexual dysfunction and menstrual irregularities. To evaluate the possible differential impact of treatment conditions on cognitive functioning including measures of attention, motor speed, problem solving, verbal and visual memory, and verbal processing speed. To measure changes in weight and health consequences associated with weight changes.

The purpose of this study is to evaluate the safety and tolerability of intramuscular injections (to the buttocks or to the shoulders) of paliperidone palmitate in patients with schizophrenia.

The purpose of the study is to show that risperidone (an antipsychotic medication) combined with lorazepam (an anti-anxiety medication) is more effective than conventional therapy administered by intramuscular injection for emergency treatment of patients with schizophrenia.

The primary purpose of the study is to show that treatment with an injectable formulation of risperidone is not less effective than and has a similar safety profile to risperidone tablets in patients with chronic schizophrenia.

The purpose of this study is to evaluate the effectiveness, safety and tolerability of risperidone long-acting injection (LAI) versus oral antipsychotics in participants with recent onset psychosis (abnormal thinking and/or hallucinations).

The purpose of this study is to evaluate the maintenance of clinical effect of a rapidly-dissolving tablet form of risperidone (an antipsychotic medication) in adult schizophrenia patients switched from their previous equivalent dose of RISPERDAL® tablets
