What is an anti-coagulant drug?

Anti-coagulant medications (such as coumadin and heparin) are used to prevent blood clots that can obstruct veins and arteries. These medications, also called blood thinners, work by blocking the action of clotting factors or platelets.

Anti-coagulant medications are used to treat a number of conditions. They are often given to reduce the risk of stroke or heart attack. They are also used during open heart or bypass surgery to reduce blood clots during surgery. Low doses of these medications are frequently given to patients who must stay in bed for long periods of time.
