Prasugrel tablets, which contain the active substance prasugrel, belongs to a group of medicines called anti
-platelet agents. Platelets are very small cell particles that circulate in the blood. When a blood vessel is
damaged, for example if it is cut, platelets clump together to help form a blood clot (thrombus).
Therefore, platelets are essential to help stop bleeding. If clots form within a hardened blood vessel
such as an artery they can be very dangerous as they can cut off the blood supply, causing a heart attack
(myocardial infarction), stroke or death. Clots in arteries supplying blood to the heart may also reduce
the blood supply, causing unstable angina (a severe chest pain).
