Rivaroxaban: a novel, oral, direct factor Xa inhibitor.

Thromboembolic disorders such as deep vein thrombosis, pulmonary embolism, myocardial infarction, and stroke often result in long-term disability and/or mortality. The anticoagulants currently available have been effective in the treatment and prevention of these disorders; however, parenteral administration, variable pharmacokinetics and pharmacodynamics, drug and dietary interactions, and a requirement for frequent monitoring of efficacy and safety limit use of these drugs. Rivaroxaban is a novel, oral factor Xa inhibitor in clinical development for the treatment and prevention of thromboembolic diseases.
