Description: Ticagrelor (AR-C 126532XX), produced by AstraZeneca, is an inhibitor of platelet aggregation. Unlike clopidogrel, ticagrelor is not a prodrug required metabolic activation. The drug was approved for use in the European Union by the European Commission on December 3, 2010, and by the US FDA on July 20,...

Ticagrelor is a reversible antagonist of the platelet purinergic P2Y12 receptor (Ki = 14 nM, IC50 = 1.8 µM), which is the main receptor responsible for ADP-induced platelet aggregation. It functions by directly changing the conformation of the P2Y12 receptor to inhibit ADP binding. Formulations containing ticagrelor...

Ticagrelor is a platelet aggregation inhibitor. It is a nucleoside analogue and blocks adenosine diphosphate (ADP) receptors of subtype P2Y12. In contrast to the other antiplatelet drugs, ticagrelor has a binding site different from ADP, making it an allosteric antagonist, and the blockage is reversible. The drug...
