Function of Edoxaban
Edoxaban is primarily used to reduce the risk of stroke and dangerous blood clots (systemic embolism) in patients with atrial fibrillation not due to valvular heart disease.
In people with atrial fibrillation, anticoagulant drugs prevent blood from forming clots in the heart to reduce the risk of stroke. It is important that a variety of these types of drugs provide more choices for patients. The researchers compared the safety and efficacy of edoxaban and warfarin in patients with atrial fibrillation requiring oral anticoagulants, observing a composite of adverse clinical events including all-cause death, thromboembolic events, and major bleeding. From the comprehensive evaluation point of view, the efficacy of edoxaban is no worse than that of warfarin. At the same time, edoxaban resulted in some higher bleeding complications (mainly gastrointestinal) compared to warfarin (or analogues available in countries). Based on these results, the trial met its primary endpoint of non-inferiority, and edoxaban may be a reasonable alternative to warfarin, although the drug was noted to increase bleeding in the study population.
