Study of Compound Edaravone Injection for Treatment of Acute Ischemic Stroke

Study Overview
=================
Brief Summary
-----------------
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.
