Mildronate an inhibitor of carnitine-dependent metabolism, is considered an anti-ischemic drug. This study aims to evaluate the efficacy and safety of mildronate injection in treating acute ischemic stroke.

A randomized, double-blind, multi-center clinical study was made on mildronate injection for treating acute cerebral infarction. 113 cases in the experimental group were given with mildronate injection, while 114 cases in the active-control group were given with cinepazide maleate injection. In addition, both groups were given aspirin as basic treatments. Modified Rankin Scale (mRS) score at 2 weeks and 3 months, National Institutes of Health Stroke Scale (NIHSS) score and Barthel Index score at 2 weeks after treatment, vital signs and adverse events were evaluated.

Exclusion Criteria:

• (i) had other intracranial pathologies (e.g. cerebral hemorrhage, tumour, infection), (ii) were pregnant or nursing ;(iii) had a neurological or psychiatric disease ;(iv) had significant drug or alcohol misuse, (v)had been given thrombolytic therapy or medication forbidden by study protocol; (vi)participated in a clinical trial in the past 3 months.
