Effects of sub-chronic antipsychotic drug treatment on body weight and reproductive function in juvenile female rats

Rationale Weight gain caused by some antipsychotics is not only confined to adults but can also adversely affect both children and adolescents. Indeed, olanzapine and risperidone have been associated with extreme weight gain in adolescents even greater than that reported in adults. We have recently shown substantial weight gain in adult female rats following treatment with olanzapine and risperidone but not ziprasidone. Objectives The aim of the present study was to compare the effects of several antipsychotics on weight gain and reproductive function in juvenile (aged 7 weeks) female hooded Lister rats. Methods Olanzapine (4 mg/kg), risperidone (0.5 mg/kg), ziprasidone (2.5 mg/kg), sulpiride (10 mg/kg), haloperidol (0.5 mg/kg) or vehicle was administered i.p. once per day for 21 days. Body weight, food and water intake were measured daily, in addition to the determination of stage of the oestrous cycle. Results Sub-chronic administration of olanzapine, risperidone, sulpiride and haloperidol, but not ziprasidone, significantly increased body weight compared to vehicle-treated animals during weeks 1–3. Sulpiride significantly increased food and water intake. Significantly increased percentage intra-abdominal fat weight was observed in olanzapine, risperidone, sulpiride and haloperidol, but not ziprasidone-treated animals. Marked disruption of the oestrous cycle was observed in all but the ziprasidone-treated group, which continued to have regular 4-day oestrous cycles. Conclusions Weight gain observed in these juvenile animals was 1.5–2 times greater than that previously observed in adult rats. These findings have important implications for the use of antipsychotics in children and adolescent patients.     

Randomized,controlled, double-blind,multicenter comparison of the cognitive effects of ziprasidone versus olanzapine in acutely ill inpatients with schizophrenia or schizoaffective disorder

Background Newer antipsychotic medications have been reported to enhance cognitive functioning in schizophrenia. Head to head studies with double-blind methods are still relatively few in number.Objectives To compare the relative cognitive enhancing effects of ziprasidone and olanzapine in the treatment of acutely ill inpatients with schizophrenia or schizoaffective disorder.Procedures In this 6-week, multicenter, double-blind, parallel-designed trial, patients were randomized to ziprasidone or olanzapine. No patient who had ever received a complete treatment trial with either of these medications previously was entered into the study. Cognitive testing measuring attention, motor speed, memory, executive functioning, and verbal skills were performed on all patients at baseline and endpoint.Results Treatment with either ziprasidone or olanzapine was associated with statistically significant improvements from baseline in attention, memory, working memory, motor speed, and executive functions. Treatment with olanzapine was also associated with a statistically significant improvement in verbal fluency. No statistically significant differences between these medications were found in the magnitude of improvement from baseline on any of the cognitive measures (other than verbal fluency in an exploratory analysis). Observed changes were not associated with changes in clinical symptoms measured using the PANSS or changes in movement disorders.Conclusions During 6 weeks of treatment, ziprasidone and olanzapine demonstrated substantial and comparable cognitive-enhancing effects relative to previous treatment. These effects were noted in all aspects of cognitive functioning previously proven to predict functional outcome in schizophrenia. No overall differences were detected between the medications in terms of the extent of cognitive enhancement.
