  • Title: Dabigatran etexilate for thromboembolic prophylaxis in non-valvular atrial fibrillation: the RE-LY study and substudies with commentary.
    Author: Waks JW, Zimetbaum PJ.
    Journal: Expert Rev Cardiovasc Ther; 2013 Nov; 11(11):1461-71. PubMed ID: 24147516.
    Abstract:
    In 2010, dabigatran etexilate, a direct thrombin inhibitor, was the first new oral anticoagulant to be approved for thromboembolic prophylaxis in atrial fibrillation in over 50 years. Dabigatran, unlike warfarin, has a short half-life with a rapid onset of anticoagulant effect, does not require dose adjustment or monitoring, and does not interact with food. The RE-LY trial compared two doses of dabigatran (110 and 150 mg twice daily) with adjusted dose warfarin in patients with non-valvular atrial fibrillation and at least 1 stroke risk factor. Compared with warfarin, dabigatran 150 mg twice daily was superior in reducing the risk of stroke or systemic embolism and was associated with a similar rate of major bleeding, while dabigatran 110 mg twice daily was equally effective in reducing stroke or systemic embolism and was associated with less major bleeding. Despite these favorable results, there remains disagreement regarding the optimal dose and overall safety of dabigatran in certain patient populations including the elderly and those with renal dysfunction.
