What is a therapeutic use of Warfarin?

Warfarin is primarily used as an anticoagulant, which means it prevents blood clot formation. This is particularly important for individuals at risk of developing clots due to various medical conditions, such as atrial fibrillation, deep vein thrombosis (DVT), or pulmonary embolism. Warfarin works by inhibiting synthesis of vitamin K-dependent clotting factors, which are essential for the blood coagulation process. By decreasing the blood's ability to clot, Warfarin helps to reduce the risk of serious complications related to clots, making it a critical medication in managing and preventing thromboembolic events.
