Mechanism of action

Acenocoumarol is a vitamin K antagonist (VKA) that works by inhibiting the vitamin K epoxide reductase complex, which is essential for the carboxylation and activation of vitamin K-dependent coagulation factors. This leads to decreased synthesis of functional factors II, VII, IX, and X, resulting in prolonged prothrombin time and reduced thrombotic risk. It is used for anticoagulation in conditions requiring long-term thromboembolic prevention.
