Antithrombotic agents are medications that help prevent blood clots from forming or growing. They are commonly used to reduce the risk of conditions like deep vein thrombosis, pulmonary embolism, and stroke. These agents work by interfering with the blood clotting process, either by inhibiting platelets or by affecting the proteins involved in coagulation. There are two main types of antithrombotic agents: anticoagulants and antiplatelet drugs. Anticoagulants, such as warfarin and heparin, slow down the clotting process, while antiplatelet drugs, like aspirin and clopidogrel, prevent platelets from sticking together. Both types are essential in managing cardiovascular diseases and improving patient outcomes.
