Rivaroxaban with the brand name Xarelto is an anticoagulant which is developed by Bayer/ Johnson & Johnson. It is commonly used for dissolving or preventing a type of blood clot that is called deep vein thrombosis (DVT) by blocking the activity of certain clotting substances in the blood.
In September 2008: Rivaroxaban gained marketing authorization from Health Canada to prevent venous thromboembolism (VTE) in people who have undergone elective total hip replacement or total knee replacement surgery. In the same month, the European Commission also granted this authorization.
In July 2011: Rivaroxaban was approved by the U.S. Food and Drug Administration for prophylaxis of deep vein thrombosis (DVT) which may lead to pulmonary embolism (PE), in adults undergoing hip and knee replacement surgery.
In November 2011: it was approved by the U.S. FDA for stroke prevention in people with common type of abnormal heart rhythm.
XARELTO is a factor Xa inhibitor indicated:
Fator Xa or Eponym Stuart–Prower Factor, is an enzyme of the coagulation cascade and activated form of the coagulation factor thrombokinase. This serine endopeptidase plays a key role at several stages of the coagulation system. It is an active component of the prothrombinase complex that catalyzes the conversion of prothrombin (factor II) to thrombin (factor IIa).
One molecule of factor Xa can generate more than 1000 molecules of thrombin so using selective inhibitors of factor Xa will be effective. Rivaroxaban is one of the competitive reversible antagonists of activated factor X (Xa); it binds directly to factor Xa and effectively blocks the amplification of the coagulation cascade, preventing the formation of thrombus.
Rivaroxaban has been approved for treating Deep Vein Thrombosis that may lead to Pulmonary Embolism and Atrial fibrillation.
According to the Bayer’s report, this drug could potentially be used on 30 million patients in its largest national markets nowadays.
In the irregular heartbeat market, Xarelto is competing with its rival pill Eliquis(Pfizer) and Bristol-Myers (Squibb), and also with Boehringer Ingelheim’s Pradaxa; but because of concerns over side effects, none of them have been tested in the atherosclerosis setting. Frank Misselwitz, head of cardiovascular drug development at Bayer believed that by considering the lowered mortality rate and a number of the cases with fatal bleeding you will be noticed that the benefits outweigh the side effect risks by far.
