What are the uses of this medicine?

Xarelto is a prescription medicine used to:

• reduce the risk of stroke and blood clots in people who have a medical condition called atrial fibrillation that is not caused by a heart valve problem. With atrial fibrillation, part of the heart does not beat the way it should. This can lead to the formation of blood clots, which can travel to the brain, causing a stroke, or to other parts of the body.
• treat blood clots in the veins of your legs (deep vein thrombosis or DVT) or lungs (pulmonary embolism or PE)
• reduce the risk of blood clots happening again in people who continue to be at risk for DVT or PE after receiving treatment for blood clots for at least 6 months.
• help prevent a blood clot in the legs and lungs of people who have just had hip or knee replacement surgery.

Xarelto is used with low dose aspirin to:

• reduce the risk of serious heart problems, heart attack and stroke in patients with coronary artery disease (a condition where the blood supply to the heart is reduced or blocked) or peripheral artery disease (a condition where the blood flow to the legs is reduced).

How does this medicine work?

• Rivaroxaban (riv" a rox' a ban) is a selective inhibitor of factor Xa, the rate controlling last step in the generation of thrombin, the final intermediate in blood coagulation.
• Inhibiting thrombin prevents the conversion of fibrinogen to fibrin and subsequent cross linking of fibrin monomers, platelet activation and amplification of coagulation.
• Rivaroxaban has been shown to be as effective as warfarin in preventing stroke and systemic embolization in patients with atrial fibrillation, and to decrease the risk of deep vein thrombosis and pulmonary embolism in patients undergoing surgery.
• Rivaroxaban is orally available and provides a reliable anticoagulant effect for which monitoring of INR is not needed.

Who Should Not Use this medicine ?

This medicine cannot be used in patients who:

• currently have certain types of abnormal bleeding.
• are allergic to rivaroxaban or any of the ingredients in Xarelto.

What drug interactions can this medicine cause?

• Avoid concomitant administration of Xarelto with known combined P-gp and strong CYP3A inhibitors (e.g., ketoconazole and ritonavir).
• Xarelto should not be used in patients with CrCl 15 to <80 mL/min who are receiving concomitant combined P-gp and moderate CYP3A inhibitors (e.g., erythromycin) unless the potential benefit justifies the potential risk.
• Avoid concomitant use of Xarelto with drugs that are combined P-gp and strong CYP3A inducers (e.g., carbamazepine, phenytoin, rifampin, St. John's wort)
• Avoid concurrent use of Xarelto with other anticoagulants (eg: enoxaparin, warfarin, aspirin, clopidogrel and chronic NSAID ) due to increased bleeding risk unless benefit outweighs risk.

Is this medicine FDA approved?

• Rivaroxaban was approved for use in the United States in 2011 and indications are for prevention of stroke and embolism in patients with chronic atrial fibrillation not related to valvular heart disease, as well as prevention and treatment of deep vein thrombosis and pulmonary embolism.

How should this medicine be used?

Treatment of DVT(deep vein thrombosis) and/or PE(pulmonary embolism):

• 15 mg orally twice daily with food for the first 21 days followed by 20 mg orally once daily with food for the remaining treatment

Reduction in the Risk of Recurrence of DVT and/or PE in patients at continued risk for DVT and/or PE:
