Active Ingredient

Acenocoumarol is a derivative of coumarin used as anticoagulant because acts as an antagonist of vitamin K. Vitamin K antagonists produce their anticoagulant effect by inhibition of the vitamin K-epoxide-reductase with a subsequent reduction of the gammacarboxylation of certain glutamic acid molecules which are located at several sites near the terminal end both of coagulation factors II (prothrombin), VII, IX, and X and of protein C or its cofactor protein S.
