Pharmacological Effects of Crushing Prasugrel in STEMI Patients

Summary

Prasugrel has shown to be superior to clopidogrel, in adjunct to aspirin, in preventing recurrent ischemic events. Prasugrel is approved in patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI) at a dosage of 60 mg loading dose (LD) followed by 10 mg/day. However, a delay in the onset of its antiplatelet effects in this particular setting has been consistently shown. administration of clopidogrel and ticagrelor crushed tablets has been tested and a faster and greater bioavailability compared to the whole tablets has been observed. However, if the administration of a crushed prasugrel LD may overcome the above limitation is still unknown and represents the aim of our study. The proposed investigation will have a prospective, randomized, design in which STEMI patients undergoing primary PCI will be randomized to receive two different formulation of prasugrel LD (60 mg whole tablets and 60 mg crushed tablets). Pharmacodynamic testing will be performed at several time points to test our study hypothesis that crushed LD regiment will achieve more prompt and enhanced platelet inhibitory effects.
