Rivaroxaban for the treatment and prevention of thromboembolic disease

ObjectivesA number of direct oral anticoagulants are now available and offer alternative strategies for anticoagulation therapy. Rivaroxaban, a direct oral Factor Xa inhibitor, is approved for use across several thromboembolic indications. This article aims to provide an overview of the key pharmacological characteristics of rivaroxaban and the rationale and evidence for the use of different dose regimens across its licenced indications, and offer practical guidance to healthcare professionals on responsible use. References were sourced via PubMed searches using the search string (rivaroxaban AND (pharmacokinetics OR pharmacodynamics OR (clinical studies) OR (drug interaction)) NOT review NOT (children OR pediatrics OR paediatrics OR adolescent)). Key findingsRivaroxaban exhibits predictable pharmacokinetics and pharmacodynamics, and thus does not require routine coagulation monitoring, unlike vitamin K antagonists (e.g. warfarin). Rivaroxaban also has a lower potential for drug-drug and food-drug interactions compared with warfarin; however, co-administration with strong inhibitors of both cytochrome P450 3A4 and P-glycoprotein is not recommended. The data indicate that dose adjustment is not necessary for age, gender or body weight. The dosing regimens of rivaroxaban vary depending on the indication, and phase III studies have demonstrated a favourable benefit-risk profile of rivaroxaban compared with traditional standard of care. SummaryRivaroxaban may offer an anticoagulant option that could simplify and improve the management of patients with thromboembolic disorders.
