Edoxaban is primarily used as an anticoagulant to prevent blood clots in patients with conditions such as atrial fibrillation, deep vein thrombosis, and pulmonary embolism. It is often prescribed to reduce the risk of stroke in individuals with non-valvular atrial fibrillation. Additionally, it is used for the treatment and prevention of recurrent venous thromboembolism. The medication works by inhibiting Factor Xa, a key component in the blood clotting process, thereby preventing the formation of harmful clots. It is typically administered orally, offering a convenient option for long-term management of thromboembolic disorders.
