Antithrombotic refers to medications or treatments that help prevent the formation of blood clots, which can lead to serious health issues like heart attacks and strokes. These agents work by inhibiting various components of the blood clotting process, ensuring that blood flows smoothly through the vessels. Common types of antithrombotic agents include anticoagulants, such as warfarin and heparin, which reduce the blood's ability to clot, and antiplatelet drugs, like aspirin, which prevent platelets from sticking together. Proper use of these medications is crucial for individuals at risk of thrombotic events.
