AIMS: To assess the effectiveness of edaravone for acute stroke including ischemic stroke and intracerebral hemorrhage (ICH). METHODS: We identified randomized controlled trials with comprehensive searches and performed systematic reviews according to the Cochrane methods of systematical reviews. RESULTS: Edaravone can reduce the rate of death or long-term disability significantly for acute ischemic stroke (AIS) (RR = 0.65; 95%CI, 0.48 to 0.89, p = 0.007). However, sensitivity analysis yielded a different result. Edaravone can also improve the short-term neurological impairment of AIS (MD = 7.09; 95%CI, 5.12 to 9.05, p < 0.00001), and ICH (MD = -4.32; 95%CI, -5.35 to -3.29, p < 0.00001). CONCLUSIONS: Edaravone is beneficial in improving neurological impairment resulting from AIS and ICH. However, currently there is no enough convincing evidence that edaravone reduces death or long-term disability for AIS and ICH.
