ABSTRACT

Objective To verify the efficacy and safety of Edaravone,a novel hydroxy-free radical scavenger,on acute cerebral infarction(ACI).Methods We performed a randomized,placebo-controlled,parallel-group,double-blind study on ACI patients. 63 patients,enrolled within 48h of onset,were allocated to Edaravone group( n = 31) or the placebo group( n = 32) randomly. Edaravone was infused at a dose of 30 mg,twice a day,for 14 days. Meanwhile,Hydroxyethylrutin and Aspirin were taken as basic treatment. The therapies of the placebo group were similar to those of Edaravone group except for Edaravone.Before treatment and at 7th,14th and 21th day after treatment,the neurological deficits and activities of daily living (ADL) were evaluated using European Stroke Scale (ESS) and Barthel Index respectively. 3 months later,all the patients were followed up for survival and ADL.Results At 21th day the increase rate of ESS was evaluted.There were significan difference between Edaravone group[(60.3?28.2)%] and the placebo group[( 35.1? 23.6)%]( P
