What do antiplatelets do?

• A. Promote platelet aggregation to increase clotting.
• B. Dilate blood vessels to raise blood pressure.
• C. Inhibit platelet aggregation to reduce risk of thrombosis.
• D. Increase red blood cell production.

Answer: (C)

Antiplatelets prevent platelets from sticking together, which stops the initial steps of clot formation inside arteries. By inhibiting platelet aggregation, these drugs reduce the risk of thrombosis, helping to lower the chances of heart attack or stroke in at-risk patients. They don’t raise blood pressure by dilating vessels, they don’t increase red blood cell production, and they don’t promote platelet clumping. Common examples include aspirin and P2Y12 inhibitors like clopidogrel, which show how the mechanism prevents aggregation.
