Antiplatelet agents are the cornerstone of treatment for patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI). Clopidogrel, when added to aspirin, has demonstrated considerable success at reducing thrombotic complications of ACS and/or PCI compared to aspirin alone and is standard of care for the management of patients with ACS and in patients undergoi...

Platelet activation and aggregation plays an integral role in the pathogenesis of acute coronary syndrome (ACS). The mainstay of ACS treatment revolves around platelet inhibition. It is known that greater platelet inhibition results in better ischemic outcomes; hence, focus in drug development has been to create more potent inhibitors of platelet aggregation. Prasugrel, a potent, third-generati...

The P2Y12 inhibitors, clopidogrel, prasugrel, and ticagrelor, are administered in fixed doses without laboratory monitoring. Randomized trials in acute coronary syndrome have shown that prasugrel and ticagrelor are more effective than standard-dose clopidogrel. Nonetheless, standard-dose clopidogrel remains widely used because it causes less bleeding and is less expensive. Patients treated with...

INTRODUCTION Dual antiplatelet therapy (DAPT) with aspirin and a thienopyridine (eg, clopidogrel) prevents stent related thromboembolic events in cardiac patients and is frequently utilized during neurointerventional surgery. However, recent data suggest that many patients exhibit clopidogrel resistance. Prasugrel-a newer thienopyridine-lowers the rate of cardiac stent thromboses in clopidogrel...

BACKGROUND Prasugrel and ticagrelor, new P2Y12-adenosine diphosphate receptor antagonists, are associated with greater pharmacodynamic inhibition and reduction of cardiovascular events compared with clopidogrel in patients with an acute coronary syndrome. However, evidence is lacking about the effects of achieving faster and stronger cyclooxygenase inhibition with intravenous lysine acetylsalic...

BACKGROUND Patients with diabetes are at increased risk of acute coronary syndromes (ACS) and their mortality and morbidity outcomes are significantly worse following ACS events, independent of other comorbidities. This systematic review sought to establish the optimum management strategy with focus on P2Y12 blockade in patients with diabetes with ACS. METHODS MEDLINE (1946 to present) and EM...

Prasugrel [2-acetoxy-5-( -cyclopropylcarbonyl-2-fluorobenzyl)4,5,6,7-tetrahydrothieno[3,2-c]pyridine], a thienopyridine antiplatelet agent, undergoes rapid hydrolysis in vivo to a thiolactone intermediate, 2-[2-oxo-6,7-dihydrothieno[3,2-c]pyridin-5(4H)-yl]-1-cyclopropyl2-(2-fluorophenyl)ethanone (R-95913), which is further converted to a pharmacologically active metabolite, 2-[1-2-cyclopropyl-1...
