Curative effects of ziprasidone and aripiprazole at acute stage on patients with drug-naive schizophrenia and their effects on metabolism of these patients / 中华神经医学杂志

ABSTRACT

Objective To compare the curative effects ofziprasidone and aripiprazole at acute stage on patients with drug-naive schizophrenia and their effects on metabolism of these patients.Methods Forty-six patients with drug-naive schizophrenia,admitted to our hospital from February 2010 to February 2011,were divided into ziprasidone treatment group (n=24,[165±13.51] mg/d) and aripiprazole treatment group (n=22,[28.86±3.06] mg/d); these patients were given the above treatment for 6 week.The scores of positive and negative syndrome scale (PANSS),body mass index (BMI),insulin resistance index (IRI),and levels of fasting blood glucose (FBG),insulin (INS),C-Peptide (CP),total cholesterol (TC),high density lipoprotein cholesterol (HDL-C),low density lipoprotein cholesterol (LDL-C),triglyceride (TG),apolipoprotein-a (APOA) and apolipoprotein-b (APOB) were obtained before and at the end of treatment.Results At the end of treatment,2 patients (9.1％) were cured,7 (31.8％)achieved obvious improvement,9 (40.9％) achieved improvement,and only 4 (18.2％) did not achieve any improvement in the aripiprazole treatment group.However,at the end of treatment,no patient (0％)was cured,7 (29.2％) achieved obvious improvement,12 (50％) achieved improvement,and 5 (20.8％)did not achieve any improvement in the ziprasidone treatment group.The total scores of PANSS after the treatment in both groups decreased significantly as compared with those before treatment (P＜0.05).The BMI ([20.14±2.63] kg/m2) in the ziprasidone treatment group at the end of treatment was obviously increased as compared with that ([19.68±2.76] kg/m2) before treatment (P＜0.05).The FBG ([4.38±0.59]mmmol/L) at the end of treatment decreased significantly as compared with those before treatment ([4.79±0.59] mmmol/L),and the BMI ([19.65±2.15] kg/m2) was obviously increased as compared with that before treatment ([19.19±2.28] kg/m2) in the aripiprazole treatment group (P＜0.05).The metabolic index in the 2 groups was not significantly different at the end of the treatment (P＞0.05).Conclusion Both ziprasidone and olanzapine are effective in the treatment of patients with drug-naive schizophrenia;both of them have mild effects on weight of patients with drug-naive schizophrenia,but no obvious effects on other metabolic indices.
