Aspirin is safer than warfarin and just as effective for treating blocked arteries in the brain
To reduce the risk of stroke, partial blockage of arteries in the brain (intracranial stenosis) has for decades been treated with drugs such as aspirin and warfarin that reduce blood clotting. However, doctors have never had good evidence for choosing one therapy over the other.
