Non-vitamin K antagonist oral anticoagulants for COVID-19 thrombosis

ABSTRACT

Thrombotic complications appear to be a major predictor of death in COVID-19 patients, and multiple studies have shown that anticoagulants can help to improve the outcome. The Food and Drug Administration's acceptance of non-vitamin K antagonist oral anticoagulants (NOACs) has sparked much excitement about their potential as a replacement for existing oral anticoagulants. NOACs target a single clotting factor, often activated factor X or thrombin, and involve the coagulation factor Xa inhibitors including apixaban, edoxaban, and rivaroxaban, and the thrombin inhibitor dabigatran. COVID-19 is an infectious disease that causes thrombotic events by inducing a pro-inflammatory and prothrombotic condition. This article provides a comprehensive overview of the mechanism behind enhanced thrombogenicity accompanying COVID-19, the clinical range of NOACs, and the role of NOACs in treatment of COVID-19 based on recent investigations and clinical trials.
