Antiplatelet drugs in arterial thrombosis: a review.
The thrombotic process, basic mechanisms of action of antiplatelet drugs, and clinical trials with platelet inhibitors are reviewed. The role of prostaglandins in platelet reactions and the mechanisms of aspirin's, dipyridamole's and sulfinpyrazone's inhibition of platelet function are discussed. Clinical studies of the use of these three drugs, alone or in combination with each other or with anticoagulants, for the treatment of thrombotic disorders associated with valvular heart disease, prosthetic heart valves, cerebral vascular disease (e.g., transient ischemic attacks), coronary artery diseases (including myocardial infarction), peripheral vascular disease, renal disease and renal allograft rejection are reviewed and evaluated. Clinical evidence suggests that antiplatelet drugs are useful in preventing thromboembolism associated with coronary and cerebral vascular disorders. In peripheral vascular and renal diseases and in renal allografts, their benefits have not been proved. Further controlled clinical studies of the preventive use of these drugs for arterial thrombosis are needed.
