This study was conducted to assess the feasibility of COX1 NSAID substitution for aspirin for preventative therapy related to circulating anticoagulants, as manifest by inhibition of platelet aggregation. There was no difference in platelet aggregation inhibition between aspirin, naproxen, ketoprofen or diclofenac and misoprostol (in combination in the form of Arthrotec). As COX1 NSAIDs appear equivalent in platelet inhibition efficacy to aspirin, therapeutic regimens can be simplified in those individuals who require an NSAID for other problems. Further, despite its short serum halflife, Arthrotec appears as effective as an antiplatelet agent. Controlled, double blind studies of efficacy in blocking clinical events (both cardiovascular and gastrointestinal) are recommended.
