The purpose of anti-platelet aggregates is thrombus prevention. Now don't get them confused with dissolve current clots. These simply prevent FUTURE thrombus formation. The mechanism of actions is the inhibition of Cyclooxygenase. Basically it works within the platelet and BV walls to dilate and prevent platelet grouping.
