Study of Compound Edaravone Injection for Treatment of Acute Ischemic Stroke

Compound Edaravone Injection for Acute Ischemic Stroke, a Multi-center, Randomized, Double-blind, Parallel, and Active-controlled PhaseⅢTrial

The primary objective of the study is to confirm the efficacy of compound Edaravone Injection via intravenous infusion every 12 hours in the patients with Acute Ischemic Stroke(AIS) in a double-blind, active-controlled manner. The study is also to examine the safety of compound Edaravone Injection for the AIS patients.
