Vitamin K antagonist

Vitamin K antagonists are medications that interfere with the body’s use of vitamin K, which is essential for producing certain blood clotting factors. By blocking vitamin K, these drugs help prevent blood clots from forming or growing, reducing the risk of conditions like stroke or pulmonary embolism. Warfarin is a common example. They require careful monitoring because they can cause excessive bleeding if doses are too high or clotting risks if too low. Essentially, they help manage and prevent abnormal clot formation by affecting the body's natural clotting process.
