Novel oral anticoagulants in chronic kidney disease: ready for prime time?

Abstract

Purpose of review: Patients with chronic kidney disease (CKD) are at increased risk of atrial fibrillation, stroke, and bleeding posing unique clinical challenges. Novel oral anticoagulants (NOACs) including dabigatran, rivaroxaban, and apixaban have become recognized as alternative therapy to Vitamin K Antagonists (VKA) regarding the prevention of venous thromboembolism (VTE) and reduce the risk of stroke in atrial fibrillation. However, the understanding of NOACs in CKD is still underdeveloped. This review summarizes recent literature on the efficacy and safety of NOACs in patients with CKD.

Recent findings: Studies focusing on patients with moderate kidney disease were drawn from post hoc analyses from three major NOAC trials, meta-analyses, and postmarketing surveillance studies. Cumulatively, these studies continue to demonstrate NOACs as equivalent if not superior therapies to VKAs in regards to both efficacy and safety. These studies are limited by small sample sizes as well as a lack of direct comparison between NOACs.

Summary: The role of NOACs in managing VTE and atrial fibrillation is increasing. Current research suggests that NOACs are at least as efficacious and well tolerated as VKAs. More research is required to elucidate which NOAC is preferable in the clinical setting.
