A control study of ziprasidone vs.risperidone in the treatment of schizophrenia

Objective To explore the efficacy and adverse reactions of ziprasidone in the treatment of schizophrenia. Methods Sixty schizophrenics were randomly divided into two groups of 30 patients each, research group took orally ziprasidone and control group did risperidone for 8 weeks. Clinical efficacies were assessed with the Positive and Negative Syndrome Scale （PANSS） , and adverse reactions with the Treatment Emergent Symptom Scale （TESS） before treatment and at the end of the 2^nd, 4^th, 6^th and 8^th week. Results After treatment, the PANSS total and each factor scores of both groups lowered more significantly compared with pretreatment （P〈0.05 or 0.01） ; at the end of the 8＇h week, obvious effective and effective rates were 66.67% and 86.7% in the research and 63.33% and 83.3% in the control group respectively, which showed no significant differences （P〉0.05） . Adverse reactions of both groups were mild, but the incidences of adverse reactions and those of extrapyramidal symptoms, menstruation changes and weight gain were significantly lower in the research than in the control group （P〈0.05）. Conclusion Both ziprasidone and risperidone are effective and equivalent in schizophrenia; but ziprasidone has higher safety, causes weight gain, menstruation changes and extrapyramidal symptoms less, and is a novel safe and effective antipsychotic.
