Betrixaban is an orally active, active site-targeting, highly potent and selective factor Xa (fXa) inhibitor (IC50 = 1.5 nM; Ki = 117 pM) with much reduced plasma kallikrein inhibitory activity (IC50 = 6.3 μM) and little potency against thrombin, trypsin, t-PA, aPC or plasmin inhibition (IC50 >10 μM). Betrixaban exhibits good pharmacokinetic properties and anticoagulant efficacy against various thromboembolism (VTE) events in vivo.
Orally active, active site-targeting, highly potent and selective factor Xa (fXa) inhibitor with anticoagulant efficacy against thromboembolism (VTE) events in vivo.

Betrixaban is a novel direct oral factor Xa inhibitor approved by the Food and Drug Administration for prophylaxis of venous thromboembolism in adult patients hospitalized for an acute illness at risk for thromboembolic complications. Assessment of the anti-coagulant effect of

Venous thromboembolism (VTE) in acute medically ill patients is a leading cause of in-hospital morbidity and mortality. A majority of these VTE events occur post-discharge, and patients remain at increased VTE risk for up to 3 months post-discharge. Recent clinical trials
Systematic SAR studies of in vitro factor Xa inhibitory activity around compound 1 were performed by modifying each of the three phenyl rings. A class of highly potent, selective, efficacious and orally bioavailable direct factor Xa inhibitors was discovered. These
Seminars in thrombosis and hemostasis, 41(2), 208-227 (2015-02-24)
A new generation of antithrombotic agents has recently emerged. These provide direct inhibition of either thrombin (factor IIa [FIIa]) or FXa, and are increasingly replacing the classical anticoagulants (heparin and coumarins such as warfarin) in clinical practice for a variety
Clinics in laboratory medicine, 34(3), 503-517 (2014-08-30)
New oral factor Xa inhibitors are intended to progressively substitute the oral vitamin K antagonists and parenteral indirect inhibitors of factor Xa in the prevention and treatment of venous and arterial thromboembolic episodes. This article focuses on the main clinical
