Mechanism of action

Warfarin is a coumarin anticoagulant that acts as a vitamin K antagonist. It inhibits the enzyme vitamin K epoxide reductase, which is essential for the carboxylation and activation of vitamin K-dependent clotting factors. This results in decreased synthesis of functional factors II, VII, IX, and X, prolonging the prothrombin time and reducing the risk of thromboembolism.
