Only clopidogrel (75 mg), which aids in preventing blood clots following stent implantation or in heart disease, is present in Clopilet 75. Clopilet A 75 is a combination of low-dose aspirin (75 mg) and clopidogrel (75 mg) that has a higher antiplatelet action to further lower the risk of clotting. These are only used if your doctor determines that aspirin is necessary for your heart disease because it increases the risk of bleeding.
