Acenocoumarol: A Review of Anticoagulant Efficacy and Safety.

Anticoagulant treatment is required for the treatment and prevention of thromboembolic disorders. Vitamin K antagonists are commonly used oral anticoagulants worldwide. Acenocoumarol is mono-coumarin derivative with racemic mixture of R (+) and S (-) enantiomers. Efficacy and safety of acenocoumarol has been evaluated in atrial fibrillation, cardiac valve replacement, after myocardial infarction, treatment of deep vein thrombosis, after major surgeries and after critical illness requiring prolonged hospitalization. Acenocoumarol is effective and safe in all age groups. It offers an advantage over warfarin in terms of better stability of anti-coagulant effect. Due to its economic advantage acenocoumarol may be suitable oral anticoagulant for long term use in countries like India. © Journal of the Association of Physicians of India 2011.
