Used as an anticoagulant to prevent blood clots in patients at risk of thromboembolic disorders such as deep vein thrombosis, pulmonary embolism, and stroke in those with atrial fibrillation. It works by inhibiting vitamin K-dependent clotting factors in the liver, thereby prolonging blood clotting time. Commonly prescribed in settings where rapid onset and short duration of anticoagulation are needed. Requires regular monitoring of INR to ensure therapeutic effectiveness and minimize bleeding risk. Often used as an alternative to warfarin in certain regions due to its shorter half-life and quicker adjustment of dose response.
