New Anticoagulants: Beyond Warfarin and Heparin. Mechanism of Action. Mechanism of action of warfarin. The minimal requirement for anticoagulant activity of the warfarin molecule is an intact 4hydroxycoumarin residue, with position 3 occupied either by a carbon residue or a hydrogen atom, enabling warfarin to act as an inhibitor of vitamin K, with major effects on some of the coagulation zymogens. - Rapid onset of action. Once a thrombus has occurred, however, the goals of anticoagulant treatment are to prevent further extension of the formed clot and to prevent secondary thromboembolic complications that may result in serious and possibly fatal sequelae.

Heparins – mechanism of action 30 The binding of antithrombin to the pentasaccharide sequence in heparin , induces a conformational change in Mechanism : Not well understood but a precipitous fall in plasma protein C or S levels (natural anticoagulants) before warfarin exert anticoagulant effect, results in procoagulant state triggering thrombosis of adipose tissue microvasculatures. Heparin is the anticoagulant of choice when a rapid anticoagulant effect is required because its onset of action is immediate when administered by intravenous injection.
