Abstract

Ischemic heart disease is the major isolated cause of death worldwide, responsible for 7,249,000 deaths in 2008, 12.7% of deaths from any causes. The inhibition of platelet activation and aggregation is an important therapeutic target. Cyclooxygenase inhibitors and thienopyridines are currently the 2 most used pharmacological classes, but novel antiplatelet agents have currently an important role. The most recent thienopyridine, prasugrel, allows an irreversible inhibition of the P2Y12 platelet receptor associated to a faster and more consistent onset of action rather the previous antiplatelet agents of the same class. Cyclopentyl-triazolo-pyrimidines, a newer pharmacological class from which ticagrelor is an example, also act at the P2Y12 platelet receptor, and like prasugrel, ticagrelor inhibits platelet aggregation in a fast and consistent manner, however, in a reversible way. This article aims to conduct a review on the literature about the most recent information and guidelines on oral antiplatelet agents available for the management of coronary disease.
