Drug Name: Warfarin
Brand Names: Coumadin, Jantoven, Marevan and Waran
Generic Name: Warfarin (war' far in)
Uses: Warfarin is an anticoagulant (blood thinner) used in treating patients with blood clots. It helps prevent blood clots from forming in blood vessels anywhere in the body after a heart attack and prevent extension of clots already formed. Warfarin is an antagonist of Vitamin K, a necessary element in the synthesis of the body’s clotting factors. Antagonism of vitamin K or a deficiency of this vitamin reduces the rate at which these factors are produced, thereby creating a state of anticoagulation.
