Abstract

Introduction: Ticagrelor, an oral P2Y12 receptor antagonist used as part of dual antiplatelet therapy in the treatment of acute coronary syndromes (ACS), has many favorable characteristics when compared with the more frequently used P2Y12 receptor antagonist clopidogrel. Ticagrelor binds reversibly, with a rapid onset and offset of action, and produces high levels of platelet inhibition without variation secondary to genetic polymorphism. Ticagrelor produces increased platelet inhibition and an overall reduction in adverse cardiac events compared with clopidogrel. Clinically relevant side effects include an increase in non-CABG-related bleeding events as well as off-target adverse effects including ventricular pauses and dyspnea.

Areas covered: This article details ticagrelor's pharmacokinetic and pharmacodynamic characteristics, development and chemical properties. The authors review relevant clinical trials looking at the efficiency and safety of ticagrelor focusing predominantly on the management of patients with ACS. Finally, the review article concludes with discussion of ticagrelor's current role and future integration into clinical practice.

Expert opinion: Ticagrelor is a promising P2Y12 receptor antagonist with characteristics that offer advantages for patients beyond those currently demonstrated by other P2Y12 receptor antagonists. The challenge for prescribers is to identify those most likely to benefit from ticagrelor treatment while minimizing unnecessary bleeding events for ‘real-world' ACS patients.
