Pharmacodynamic study of prasugrel or clopidogrel in non-ST-elevation acute coronary syndrome with CYP2C19 genetic variants undergoing percutaneous coronary intervention (PRAISE-GENE trial)

摘要

Background: The CYP2C19*2 or *3 loss-of-function (LOF) allele is associated with high platelet reactivity (HPR) on clopidogrel treatment. East Asians may benefit from a lower dose of prasugrel due to their more potent platelet inhibitory response. The impact of LOF alleles on the pharmacodynamic response to half-dose prasugrel in patients with non-ST-elevation acute coronary syndrome (NSTE-ACS) undergoing percutaneous coronary intervention (PCI) is unknown.
