Antiplatelet drugs are medications that help prevent blood clots by inhibiting the aggregation of platelets, which are small cells in the blood that play a key role in clot formation. These drugs are commonly prescribed to reduce the risk of heart attacks and strokes, especially in individuals with cardiovascular diseases. Common examples of antiplatelet drugs include aspirin and clopidogrel. They work by blocking specific receptors on the surface of platelets, making it harder for them to stick together. By reducing the likelihood of clot formation, these medications help maintain healthy blood flow and lower the risk of serious cardiovascular events.
