OBJECTIVE:To systematically review the efficacy,safety and economy of acarbose versus metformin in the treat-ment of type 2 diabetes,and provide evidence-based reference for the clinical treatment. METHODS:Retrieved from PubMed, Medline,CJFD,Wanfang database,VIP database,randomized controlled trails (RCT) about acarbose (test group) versus metfor-min(control group)in the treatment of type 2 diabetes were collected. Meta-analysis was performed by using Rev Man 5.2 statis-tics software,and the decision tree model was used to do the cost-effectiveness analysis by using TreeAge Pro 2011.1.0.12.1 soft-ware. RESULTS:A total of 8 RCT,involving 418 patients. Results of Meta-analysis showed 2 h postprandial blood glucose (2 h PG)in test group [MD=-2.21,95%CI(-2.92,-1.51),P<0.001] was lower than that of control group,there was no signifi-cant diffcrencc in the glycated hemoglobin levels[MD=0.02,95%CI(-0.38,0.34),P=0.91],fasting blood glucose level[MD=0.05,95%CI(0.91,1.01),P=0.92] and incidence of adverse reactions [OR=1.84,95%CI(0.80,4.24),P=0.92] between 2 groups. Results of decision tree analysis showed the cost-effectiveness ratio in test group and control group was 847.15 and 272.53,respec-tively;and incremental cost-effectiveness ratio was 13 776. CONCLUSIONS:Acarbose shows an obvious advantage on decreasing the 2 h PG of type 2 diabetes,however,pharmacoeconomics shows metformin has higher economic effects. Due to the limit of methodological quality,large-scale and high quality RCT are required for further validation of the conclusions.
