IntroductionAll oral P2Y12 receptor blockers are associated with some degree of delayed onset and offset of pharmacodynamic (PD) effects in patients with acute coronary syndromes (ACS) undergoing percutaneous coronary intervention (PCI). Although intravenous glycoprotein IIb/IIIa inhibitors are associated with rapid onset of action, they are also associated with delayed offset and other limitations such as elevated bleeding risk and thrombocytopenia. Areas covered: In this review, the authors focus on cangrelor, an intravenous, reversible P2Y12 receptor blocker with fast onset and offset of effects. The authors also describe the pharmacologic effects of cangrelor and its pharmacologic interaction with other P2Y12 receptor inhibitors. Finally, the authors discuss the large-scale clinical trials that compared the efficacy and safety of cangrelor with clopidogrel. Expert opinion: In ACS patients undergoing PCI, cangrelor is most desirable to effectively prevent periprocedural ischemic events and to avoid excessive bleeding. Indeed, any high-risk patient with ST-segment elevation myocardial infraction or patient who is unable to take oral medications is a potential candidate for intravenous cangrelor therapy. Furthermore, stable patients with coronary artery disease, who are considered for ad hoc PCI following coronary angiography, may be considered for treatment with cangrelor to reduce post-PCI thrombotic events.
