Rivaroxaban (BAY 59-7939) is an oral anticoagulant under development by Bayer; it will be marketed as Xarelto. It acts by inhibiting the active form of coagulation factor X (factor Xa).

[edit] Development
Rivaroxaban is an oxazolidinone derivative optimised for binding with factor Xa.[1] If marketed, it will be a joint product by Bayer and Ortho-McNeil Pharmaceutical.[2]
[edit] Uses
[edit] Expected
Due to the decreased need for monitoring, rivaroxaban is likely to be used to replace warfarin for a number of indications, such as atrial fibrillation.[3]
[edit] Trial results
In phase IIb trials it was effective in reducing thromboembolic complications (deep vein thrombosis and pulmonary embolism) after orthopedic surgery[4] and it is under investigation for the treatment of DVT and PE and for anticoagulation in atrial fibrillation.[3] Advantages are the oral administration (a benefit over low molecular weight heparins, which require subcutaneous injections) and no need for monitoring (an advantage over warfarin). In studies, dosages of 2.5-10 mg once or twice daily were used.[4]
On July 8, 2007, Bayer sponsored Phase 3 clinical trial data showing once-daily rivaroxaban achieved superior efficacy in the prevention of venous thromboembolism (VTE) in patients undergoing knee replacement surgery in comparison with enoxaparin, a LMWH.[5]
[edit] Related drugs
Ximelagatran, a direct thrombin inhibitor, was not marketed further due to its potential side-effects; the related compound dabigatran was recently approved in the European Union. Together with rivaroxaban, the related factor Xa-inhibitor apixaban (Bristol-Myers-Squibb) and LY517717 (Lilly) are under development as non-monitored antithrombotic drugs.[6]
