Antiplatelet medicines keep blood clots from forming by preventing blood platelets from sticking together. They are used as part of a treatment for patients with atherosclerosis or with increased clotting tendencies.
Atherosclerosis is the process by which deposits of cholesterol form along inner walls of blood vessels, creating conditions for blood clots to form.
Antiplatelets are generally prescribed preventively, when atherosclerosis is evident but there is not yet a large obstruction in the artery.
Antiplatelet drugs include aspirin, ticlopidine (Ticlid ®), Clopidogrel (Plavix ®) and aspirin/dipyrimadole (Aggrenox ®).
Aspirin is an important therapeutic agent for stroke prevention. It's a medicine that can save your life if you have heart problems, or if you have had a stroke or TIA. You must use aspirin just as your doctor tells you.
