Description

Betrixaban is an anticoagulant drug which acts as a direct factor Xa inhibitor. Betrixaban is now being developed by Portola Pharmaceuticals. Oral, once-daily Factor Xa inhibitor anticoagulant that directly inhibits the activity of Factor Xa, an important validated target in the blood coagulation pathway, to prevent life-threatening thrombosis. U.S. Food and Drug Administration granted Fast Track designation to betrixaban for extended-duration prevention of venous thromboembolism (VTE; blood clots) in acute medically ill patients (i.e., those who are hospitalized for serious medical conditions, such as heart failure, stroke, infection and pulmonary disease). Has the potential to become the first oral Factor Xa inhibitor anticoagulant approved for hospital-to-home prevention of VTE in acute medically ill patients.
