Direct Oral Anticoagulant Agents: Pharmacologic Profile, Indications, Coagulation Monitoring, and Reversal Agents

Vitamin K antagonists (VKAs), such as warfarin, have been used for thromboprophylaxis and for the treatment of thromboembolic events in patients with nonvalvular atrial fibrillation for over 60 years. The increasing use of direct oral anticoagulants (DOACs) in recent years has shown greater advantages and safer use over VKA, including reduced bleeding, fewer drug interactions, no food interactions, a quick onset and offset of activity, and predictable dose-response properties. Despite their advantages, there are a couple of major limitations that raise concerns among clinicians, including the need for more coagulation assays to monitor their effects and more specific reversal antidotes in life-threatening circumstances of bleeding.
