Approximately one-third of persons with depression do not respond to antidepressant monotherapy. Studies suggest that atypical antipsychotic augmentation may benefit these patients. We investigated the longer-term efficacy of risperidone augmentation of serotonin-selective reuptake inhibitor treatment for resistant depression. In 57 in- and outpatient(More)
BACKGROUND Standard treatment for acute psychotic agitation often involves intramuscular administration of the benzodiazepine lorazepam and the antipsychotic haloperidol. This study compared the efficacy and safety of oral treatment with the atypical antipsychotic risperidone plus lorazepam with those of standard intramuscular treatment. We hypothesized(More)
BACKGROUND Case series suggest that some antipsychotics may induce or exacerbate type 2 diabetes. This study measured the association of antipsychotic treatments with diabetes at a population level. METHOD Claims data for psychosis patients (ICD-CM-9 290.xx-299.xx) within health plans encompassing 2.5 million individuals were analyzed. Patients reporting(More)
We describe the design of a multicenter, randomized clinical trial to compare clinical, quality-of-life, and economic outcomes in patients with schizophrenia or schizoaffective disorder who were treated with risperidone or any of 13 conventional antipsychotic drugs approved for use in the United States. This 1-year trial was designed to approximate(More)
OBJECTIVE This study compared the effects of atypical antipsychotics (risperidone or quetiapine) with placebo and with each other in recently exacerbated patients with schizophrenia requiring hospitalization. METHODS This international, randomized, double-blind study included a 2-week monotherapy phase followed by a 4-week additive therapy phase. Recently(More)
OBJECTIVE The safety and efficacy of risperidone and olanzapine were compared in a double-blind trial that used doses widely accepted in clinical practice. METHOD Subjects (N=377) who met DSM-IV criteria for schizophrenia or schizoaffective disorder were randomly assigned to receive 2-6 mg/day of risperidone (mean modal dose=4.8 mg/day) or 5-20 mg/day of(More)
OBJECTIVE The authors compared paliperidone extended-release and quetiapine in patients with recently exacerbated schizophrenia requiring hospitalization. METHOD In a 6-week double-blind study, inpatients with a recent exacerbation of schizophrenia were randomly assigned to treatment with paliperidone extended-release, quetiapine, or placebo. A 2-week(More)
OBJECTIVE Atypical antipsychotics induce weight gain and are linked to increased diabetes risk, but their relative impact on factors that elevate disease risk are unknown. METHODS We performed a 6-month, randomized, double-blind study to evaluate the effects of risperidone and olanzapine in patients with schizophrenia. At baseline and weeks 6 and 24, we(More)
OBJECTIVE Antipsychotic medications differ in their sedative potential, which can affect cognitive performance. The primary objective of this double-blind study was to compare the effects of treatment initiation with risperidone and quetiapine on cognitive function in subjects with stable bipolar disorder. METHOD Subjects had a DSM-IV diagnosis of bipolar(More)
This post hoc analysis explored the role of insight as a mediator of functioning in a 52-week, double-blind, international trial of 323 patients with schizophrenia or schizoaffective disorder receiving risperidone long-acting injectable. Measures included the Positive and Negative Syndrome Scale (PANSS) insight item, PANSS factors, Clinical Global(More)
