Anti-thrombotic agents are medications used to prevent blood clots from forming in your blood vessels. They are commonly prescribed to reduce the risk of heart attacks, strokes, and other serious conditions related to abnormal blood clotting. These medications help keep your blood flowing smoothly and can be essential for people with conditions like atrial fibrillation, deep vein thrombosis, or those who have had certain surgeries. Always follow your doctor's advice and take these medications as directed to protect your heart and blood vessels.
