Abstract: Ticagrelor is a recently approved oral antiplatelet agent that belongs to a new chemical class, the cyclopentyltriazolopyrimidines (CPTP). Ticagrelor is rapidly absorbed, with a median time to maximum concentration of 1.5 hours. The new drug possesses advantages compared with other P2Y12 receptor antagonists such as clopidogrel and prasugrel in that it acts more quickly with no necessity of metabolic activation, bonds to P2Y12 receptor reversibly and therefore the platelet function can recover rapidly after drug withdrawal. Furthermore, ticagrelor may confer additional pharmacological effect via inhibition of non-platelet P2Y12 receptors. The pharmacokinetic characteristics of ticagrelor are not influenced by age, gender, diet, or clopidogrel responsiveness. Ticagrelor is primarily metabolized by cytochrome P450 (CYP) 3A4, rapidly produces plasma concentration-dependent IPA and can overcome non-responsiveness in patients previously treated with clopidogrel. What's more, CYP2C19 and ABCB1 genotypes show no effects on the pharmacodynamic profile of ticagrelor. This review summarized recent progress in pharmacokinetics, pharmacodynamics and pharmacogenetics of ticagrelor.

Key words: ticagrelor, pharmacokinetics, pharmacodynamics, pharmacogenetics
