[Combined antithrombotic treatment : do we have to add an antiplatelet drug to an anticoagulated-patients ?].

Antithrombotic drugs are regularly prescribed for the treatment and prevention of venous or arterial thromboembolic events. The co-prescription of an anticoagulant and antiplatelet drug is frequent in daily practice even if evidence of benefit associated with such an association is limited, while the increased bleeding risk is well established. The aim of this article is to review the situations where antiplatelet drugs are indicated in patients already treated with long-term anticoagulants. The perspective of adapting and personalizing antithrombotic therapy according to each patient's characteristics is also discussed.
