New reversal agent for factor Xa inhibitors shows promise
Commentary on: Siegal DM, Curnette JT, Connolly SJ, et al.. Andexanet alfa for the reversal of Factor Xa inhibitor activity. N Engl J Med 2015;373:2413–24. Context Direct oral anticoagulants (DOACs) have emerged as alternatives to vitamin K-antagonists (eg, warfarin) for the long-term management of stroke prevention for non-valvular atrial fibrillation or venous thromboembolic disease. Favourable side-effect profiles and absence of therapeutic monitoring are important benefits of these newer agents. Warfarin is readily reversed with fresh frozen plasma (FFP) or prothrombin complex concentrates.1 The first reversal ag...

Practical use of dabigatran etexilate for stroke prevention in atrial fibrillation
Summary Atrial fibrillation (AF) is associated with an increased risk of thromboembolism, and is the most prevalent factor for cardioembolic stroke. Vitamin K antagonists (VKAs) have been the standard of care for stroke prevention in patients with AF since the early 1990s. They are very effective for the prevention of cardioembolic stroke, but are limited by factors such as drug–drug interactions, food interactions, slow onset and offset of action, haemorrhage and need for routine anticoagulation monitoring to maintain a therapeutic international normalised ratio (INR). Multiple new oral anticoagulants have been develope...
