Which stroke drug is safest? 2,000-patient study aims to find out
NCT ID NCT07604298
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at 2,000 people who had a stroke to see which blood-thinning medicine works best to stop another stroke. The drugs being compared are indobufen, aspirin, cilostazol, and clopidogrel, used alone or in pairs. Researchers will track strokes and bleeding problems for one year after treatment starts. The goal is to help doctors choose the safest and most effective drug for each patient.
