Clinical Efficacy of α-Lipoic Acid versus Epalrestat in the Treatment of Diabetic Peripheral Neuropathy:A Systematic Review / 中国药房

ABSTRACT

OBJECTIVE:To systematically review the efficacy of α-lipoic acid versus epalrestat in the treatment of diabetic pe-ripheral neuropathy(DPN),and provide evidence-based reference for clinic. METHODS:Retrieved from CJFD,CBM,VIP,Wan-fang Database and PubMed,randomized controlled trials(RCT)about α-lipoic acid versus epalrestat in the treatment of DPN were collected,and the study was screened by inclusion and exclusion criteria. Meta-analysis was performed by using Rev Man 5.3 soft-ware after data extraction and quality evaluation by Cochrane software. RESULTS:Totally 6 RCTs were enrolled,involving 408 pa-tients. Results of Meta-analysis showed,compared with epalrestat,there were no significant differences in the total effective rate [RR=0.98,95%Cl(0.84,1.15),P=0.81],motor nerve conduction velocity [median nerveMD=1.02,95%Cl(-1.10,3.14),P=0.34;common peroneal nerveMD=0.23,95%Cl(-1.11,1.58),P=0.73] and sensory nerve conduction velocity [median nerveMD=1.10,95%Cl(-0.39,2.59),P=0.15;common peroneal nerveMD=0.95,95%Cl(-1.47,3.36),P=0.44] in α-lipoic acid group. CONCLUSIONS:The efficacy of α-lipoic acid is similar to epalrestat in the treatment of DPN,as well as the motor nerve conduction velocity and sensory nerve conduction velocity of median nerve or common peroneal nerve.
