齐拉西酮与利培酮治疗精神分裂症的对照研究

A comparative study of Ziprasidone and Risperidone in the treatment of schizophrenia

目的:比较齐拉西酮与利培酮治疗精神分裂症的疗效及不良反应。方法:将符合中国精神精神障碍分类与诊断标准第3版诊断标准的精神分裂症患者100例随机分成齐拉西酮组与利培酮组,每组各50例,疗程8周。采用阳性与阴性症状量表(PANSS)及副反应量表(TESS)评定疗效和不良反应。结果:齐拉西酮组显效率及有效率分别为72%和92%,利培酮组分别为70%和90%,两组疗效相仿(P>0.05)。齐拉西酮在治疗两周末阴性症状因子即有下降,而利培酮组在治疗4周末才显著下降。齐拉西酮组锥体外系反应、体重增加、失眠等副反应少于利培酮组。结论:齐拉西酮对精神分裂症患者的疗效与利培酮相仿,不良反应较轻微,阴性症状改善较快。

Objective：To compare the clinical efficacy and side effect of Ziprasidone with those of Risperidone in the treatment of schizophrenia. Methods ：100 schizoprenics were randomly assigned to receive Ziprasidone or Risperidone treatment for 8 weeks. The clinical efficacy was assessed with the Positive and Negative Syndrome Scale （PANSS）, and the side effect was assessed with the Treatment Emergent Symptom Scale （TESS） before treatment and at the end of the 8th week treatment. Results： At the end of the 8th week, the obviously effective rate and effective rate were 72% and 92% respectively in Ziprasidone group,and were 70% and 90% in Risperidone group. There was not significant difference between the two groups in the clinical efficacy. The score of negative symptoms descended in Ziprasidone at the end of the 2th week, and descended in Risperidone at the end of the 4th weeks. The incidence of the extrapyramidal symptoms, as well as of the insomnia and obesity were lower in Ziprasidone than in Risperidone. Conclusion： Compare with Risperldone,Ziprasldone has the same efficacy and lower side effect.
