Betrixaban (Bevyxxa)

General information

Class/mechanism: Direct factor Xa inhibitor. By inhibiting free and clotbound factor Xa in the coagulation cascade, betrixaban inhibits prothrombinase activity, the conversion of prothrombin to thrombin, and the subsequent conversion of fibrinogen to fibrin. It does not need antithrombin III to exert its antithrombotic activity.
Route: PO
Extravasation: n/a
