Condition(s) targeted: Cerebral Infarction; Atherosclerosis

Intervention: clopidogrel (Drug); Cilostazol (Drug)

Phase: Phase 4

Status: Completed

Sponsored by: Asan Medical Center

This study will recruit 480 acute stroke patients with symptomatic intracranial stenosis (M1 segment of Middle cerebral artery (MCA) or basilar artery). They will be randomly assigned into cilostazol group or clopidogrel group. Every patients will take 100mg of aspirin a day additionally. The primary outcome variable of this study is Progression rate of symptomatic intracranial stenosis on magnetic resonance angiogram (MRA).
