Rivaroxaban (BAY 59-7939) is an oral anticoagulant invented and manufactured by Bayer; in a number of countries it is marketed as Xarelto. In the United States, it is marketed by Janssen Pharmaceutica. It is the first available orally active direct factor Xa inhibitor. Rivaroxaban is well absorbed from the gut and maximum inhibition of factor Xa occurs four hours after a dose. The effects lasts 8–12 hours, but factor Xa activity does not return to normal within 24 hours so once-daily dosing is possible. There is no specific way to reverse the anticoagulant effect of rivaroxaban in the event of a major bleeding event, unlike warfarin
In September 2008, Health Canada granted marketing authorization for rivaroxaban as one 10 mg tablet taken once daily for the prevention of venous thromboembolism (VTE) in patients who have undergone elective total hip replacement or total knee replacement surgery.
In September 2008, the European Commission granted marketing authorization of rivaroxaban for the prevention of venous thromboembolism in adult patients undergoing elective hip and knee replacement surgery. In December 2011 rivaroxaban has been approved by the European Commission for use in two new indications: prevention of stroke and systemic embolism in adult patients with non-valvular atrial fibrillation (AF) with one or more risk factors and treatment of deep vein thrombosis (DVT) and prevention of recurrent DVT and pulmonary embolism (PE) following an acute DVT in adults.
On July 1, 2011, the U.S. Food and Drug Administration (FDA) approved rivaroxaban for prophylaxis of deep vein thrombosis (DVT), which may lead to pulmonary embolism (PE), in adults undergoing hip and knee replacement surgery. On November 4, 2011, the U.S. FDA approved rivaroxaban for stroke prophylaxis in patients with non-valvular atrial fibrillation. On November 2, 2012, the U.S. Food and Drug Administration (FDA) approved rivaroxaban for the treatment of patients with deep vein thrombosis (DVT) and pulmonary embolism (PE) and for long-term treatment to prevent recurrence.
