Rivaroxaban is a factor Xa inhibitor used to treat deep vein thrombosis (DVT) and pulmonary embolism (PE). May also be used as thrombosis prophylaxis in specific situations.
Rivaroxaban competitively inhibits free and clot bound factor Xa. Factor Xa is needed to activate prothrombin (factor II) to thrombin (factor IIa). Thrombin is a serine protease that is required to activate fibrinogen to fibrin, which is the loose meshwork that completes the clotting process. Since one molecule of factor Xa can generate more than 1000 molecules of thrombin, selective inhibitors of factor Xa are profoundly useful in terminating the amplification of thrombin generation. The action of rivaroxaban is irreversible.
Rivaroxaban is indicated for the prevention of venous thromboembolic events (VTE) in patients who have undergone total hips replacements and total knee replacement surgery; prevention of stroke and systemic embolism in patients with nonvalvular atrial fibrillation; treatment of deep vein thrombosis (DVT) and pulmonary embolism (PE); to reduce risk of recurrent DVT and/or PE. Rivaroxaban is also indicated, in combination with aspirin, for reducing the risk of major cardiovascular events in patients with chronic coronary artery disease or peripheral artery disease. Its use is also not recommended in those with severe renal impairment (<30mL/min). Rivaroxaban is also indicated for the treatment and prevention of VTE in pediatric patients (from birth to 18 years of age) and for thromboprophylaxis in pediatric patients ≥2 years old with congenital heart disease following the Fontan procedure.
