Why are antiplatelets used?

How do they work?

Antiplatelets prevent blood clots from forming in your blood vessels and heart. This can prevent a heart attack or stroke.

Antiplatelets slow the blood's clotting action by reducing the clumping of platelets. Platelets are cells that stick together, or clump, and help to form blood clots. These medicines keep platelets from clumping together. This helps to prevent blood clots from forming or getting bigger.
