Apixaban is a direct inhibitor of activated factor X (FXa) and is given orally for the prophylaxis of a range of conditions including VTE in adults after hip or knee replacement surgery, recurrent DVT, and stroke in patients with non-valvular atrial fibrillation.
Apixaban does not require routine anticoagulant monitoring but measurement would be required in certain clinical situations where the result will alter management, including prior to emergency surgery or when bleeding.
