Warfarin is an anticoagulant commonly used in the prevention of thrombosis and thromboembolism. Its use is studied in stroke and pulmonary fibrosis patients among many others. It is used to study potential risks and interactions with other drugs and food.

Biochem/physiol Actions

Warfarin consists of a racemic mixture of two active enantiomers, R- and S- forms. Warfarin is slower-acting than the common anticoagulant heparin. Warfarin inhibits the vitamin K-dependent synthesis of biologically active forms of the calcium-dependent clotting factors II, VII, IX and X. It inhibits regulatory factors protein C, protein S, and protein Z.
