Dabigatran is primarily used as an anticoagulant to prevent and treat blood clots. It is commonly prescribed for patients with atrial fibrillation to reduce the risk of stroke. It is also used for the prevention of deep vein thrombosis (DVT) and pulmonary embolism (PE) in patients who have undergone hip or knee replacement surgery. Additionally, it is effective in treating existing DVT and PE and preventing their recurrence. Dabigatran works by directly inhibiting thrombin, a key enzyme in the blood clotting process, offering an alternative to traditional anticoagulants like warfarin. Its predictable pharmacokinetics and lack of need for regular blood monitoring make it a convenient option for many patients.
