Abstract:Objective To evaluate the side effects of Aripiprazole and Olanzapine on blood glucose and blood lipids of patients with schizophrenia using meta-analysis. Methods The databases such as CBM, VIP, CNKI, WanFang, PubMed, Elsevier and Cochrane Library, etc. were searched to collect randomized controlled trials (RCTs) from January 1, 2011 to July 31, 2015, and the relevant Internet literature and books were also searched by hand. The literature quality was independently evaluated and cross-checked by three reviewers according to the Cochrane collaboration bias scale, and meta-analysis was applied to the results of homogeneous studies with RevMan 5.2 software. Results A total of 9 randomized controlled studies (915 patients) were included. The meta-analysis results showed that the levels of fasting blood glucose, triglycerides and cholesterol of the patients with schizophrenia significantly increased after taking regular doses of Olanzapine compared to those taking Aripiprazole (P < 0.05). Conclusions Aripiprazole is more secure than Olanzapine in aspects of blood glucose, blood lipids and other side-reactions in patients with schizophrenia.
