Warfarin(also known by the brand names Coumadin, Jantoven, Marevan, Uniwarfin) is an anticoagulant initially introduced in 1948 as a pesticide against rats and mice. In the early 1950s, it was found to be effective and relatively safe for preventing thrombosis and thromboembolism in many disorders. It was approved for use as a medication in 1954, and has remained popular ever since. It is the most widely prescribed oral anticoagulant drug in North America. Warfarin decreases blood coagulation by inhibiting vitamin K. For detailed information on this drug, please visit
