Clinical Utility

Apixaban is an oral factor Xa inhibitor that is indicated to reduce the risk of stroke and systemic embolism in patients with nonvalvular atrial fibrillation. It is also indicated for the treatment, prophylaxis, or the reduction in the risk of recurrence of deep vein thrombosis (DVT) or pulmonary embolism (PE). Apixaban does not need to be monitored routinely, however, exceptions may include determination of failure of therapy vs. poor compliance, or potential dose adjustment required for renal or hepatic dysfunction.
