Management of Major Bleeding with the Non-Vitamin K Oral Anticoagulants: the Role of Antidotes

Abstract

Over the recent years, new oral anticoagulant agents have been developed and entered the clinical arena, the direct or non-vitamin K oral anticoagulants (NOACs). Although more expensive, these agents have been proven as equivalent or superior to vitamin K antagonists in the treatment of non-valvular atrial fibrillation (AF) and venous thrombo-embolism with a lower incidence of intracerebral hemorrhage. Nevertheless, occurrence of major or life-threatening bleeding events is still quite possible. Thus, there is a major concern regarding the lack of a specific antidote and rapid reversal agent in such disastrous situations. Fortunately, the development of effective specific NOAC antidotes has recently made great advances, which are herein briefly reviewed.
