Dabigatran is an anticoagulant medication used to prevent blood clots in patients with certain conditions, such as atrial fibrillation and after certain types of surgery. It works by inhibiting a specific enzyme called thrombin, which plays a key role in the blood clotting process. This medication is taken orally and is often preferred because it does not require regular blood monitoring like some other anticoagulants. However, patients should be aware of potential side effects, including an increased risk of bleeding, and should consult their healthcare provider for proper guidance and management.
