Objective To assess the effectiveness and safety of sodium ozagrel combined with edaravone for cerebral infarction. Methods Such databases as PubMed (1995 to 2010), EMCC (1995 to 2010), CBM (1995 to 2010), CNKI (1995 to 2010), and VIP (1989 to 2010) were searched to collect randomized controlled trials (RCTs) of odium ozagrel combined with edaravone for cerebral infarction. Then the retrieved studies were screened according to the predefined inclusion and exclusion criteria, the data were extracted, the quality of the included studies was evaluated, and meta-analyses were performed by using the Cochrane Collaboration’s RevMan 5.0 software. Results A total of 32 RCTs involving 3 059 cases were involved, among which 1 559 cases were in the treatment group and the other 1500 were in the control group. All studies with comparable baseline data reported the application of random methods without explaining the detailed methods, the blinding method and the allocation concealment. The results of meta-analyses indicated that sodium ozagrel combined with edaravone had significant differences in the effective rate for cerebral infarction compared with both single sodium ozagrel (OR=3.51, 95%CI 2.70 to 4.57) and routine treatment (OR=3.77, 95%CI 2.58 to 5.52), and it had significant differences in treating the defect of neurological function compared with both sodium ozagrel (WMD= –4.26, 95%CI –4.97 to –3.55) and routine treatment (WMD= –3.89, 95%CI –4.96 to –2.82). In addition, Sodium ozagrel combined with edaravone was superior to sodium ozagrel (WMD=13.57, 95%CI 9.84 to 17.30) in improving the ability of daily living. Conclusion This systematic review shows that sodium ozagrel combined with edaravone is quite effective in treating cerebral infarction, and it can improve the nerve dysfunction. This conclusion should be treated cautiously for the poor quality and higher possibility of bias in the included studies which may impact on the power of proof, so more double-blind RCTs with high quality are expected to provide high-quality evidence.
