Summary

Recently, two new oral P2Y12 antagonists have been approved for clinical use: prasugrel, a third generation thienopyridine, and ticagrelor, a first in class cyclopentyltriazolopyrimidine (CPTP). These agents have been shown to be associated with more potent platelet inhibitory effects compared with clopidogrel. In addition, both agents have shown to be superior to clopidogrel in preventing recurrent ischemic events in the setting of acute coronary syndromes (ACS). Understanding how to switch patients from prasugrel to ticagrelor is an unmet need of clinical interest. The proposed PD investigation will have a prospective, randomized, parallel design aimed to show that switching patients from prasugrel to ticagrelor provides similar levels of platelet inhibition.
