Rivaroxaban – An anticoagulant with a difference

Blood thinners or anticoagulants are chemical substances that prevent or reduce the coagulation of blood, thereby prolonging the clotting time.

Anticoagulants are a class of drugs that are similar to antiplatelet drugs and thrombolytic drugs by manipulating the various pathways of blood coagulation.

Historically, warfarin and Heparin were two main vitamin K antagonists (VKAs), oral anticoagulant (OACs) drugs available in the market.

But very recently in the year 2007, non-vitamin K oral anticoagulants (NOACs), including factor Xa inhibitors Rivaroxaban was patented and approved for medical use in the United States in 2011.

Rivaroxaban is specifically used to treat deep vein thrombosis and pulmonary emboli and prevent blood clots in atrial fibrillation and following hip or knee surgery.



CAS No - 366789-02-8

Rivaroxaban acts as an anticoagulant by selectively, directly, and reversibly inhibiting free and clot-associated factor Xa in human plasma without binding to antithrombin.

Rivaroxaban is well tolerated, with a predictable pharmacokinetic profile, without the need for laboratory monitoring.
