That ubiquitous pharmaceutical, aspirin, delivers yet again in modern pharmacology. According to John Marler of the National Institute of Neurological Disorders and Stroke (NINDS), aspirin works just as well as warfarin in reducing blood clotting. Aspirin and warfarin have been used to reduce the risk of stroke, partial blockage of arteries in the brain (intracranial stenosis) for several years. The latest double-blind, randomized clinical trial shows for the first time that aspirin is equally as effective as warfarin and has fewer side effects. Marler explains this is good news for patients because a simple low-cost drug that works just as well one that is more expensive and more complicated to administer and monitor means less medical intervention and lower healthcare costs.
