Direct oral anticoagulants in the treatment and long-term prevention of venous thrombo-embolism.

ABSTRACT

Direct oral anticoagulants (DOACs) specifically target factor IIa or Xa and represent a major step forward in the treatment of acute- and long-term prevention of venous thrombo-embolism (VTE). They are at least as effective and as safe as conventional therapy (heparins and vitamin-K inhibitors) and have practical advantages, such as fixed dosing and no need for laboratory monitoring. These antithrombotic agents introduce a new paradigm for the day-to-day management of VTE. Direct oral anticoagulants should streamline the management of most patients with VTE and will facilitate care in the outpatient setting. Nevertheless, it remains uncertain how to select specific DOACs for particular profiles of patients, and the optimal management of bleeding complications is evolving.
