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 undergoing PCI. Prasugrel is a novel thienopyridine antiplatelet agent recently approved for the treatment of patients with ACS undergoing PCI. Prasugrel provides greater and more consistent platelet inhibition than clopidogrel due to earlier and more extensive formation of its active metabolite. The enhanced platelet inhibition with prasugrel led to a reduction in major adverse cardiovascular events in patients with moderate to high risk ACS scheduled for PCI in the phase 3 TRITON-TIMI 38 trial. This benefit was seen more in patients suffering a STEMI and those with diabetes. However, this reduction ...

Three P2Y12 inhibitor options (clopidogrel, prasugrel and ticagrelor) are currently available, all having different efficacy and safety profiles along with contrasting contraindications, special warnings and precautions for use. This review compares and contrasts the unique P2Y12 antagonists in the NSTE-ACS setting, covering the latest evidence and their optimal use.

AF is the most frequently diagnosed arrhythmia in the United States. The most serious side effect of AF is stroke. Warfarin has several decades of proven efficacy in AF-related stroke prevention but the drug's numerous drawbacks make its implementation difficult for practitioners and patients. The difficulties of warfarin have prompted the development of alternative anticoagulants for AF-related stroke prevention with better efficacy, safety, and convenience. The oral direct thrombin inhibitor, dabigatran, and the oral factor Xa inhibitors, rivaroxaban and apixaban, have been evaluated in a large phase III trial. Dabigatran, rivaroxaban and apixaban were shown to be noninferior compared with warfarin in the prevention of stroke. Dabigatran and apixaban were found to be statistically superior to warfarin. All three may also...

However, dual antiplatelet therapy reduces the risk of stent thrombosis and cardiovascular events compared with aspirin alone in the treatment of patients with ACS. Recently, there has been debate as to which antiplatelet agent should be added to aspirin in the ACS treatment regimen. This review summarizes the pharmacologic and clinical data comparing clopidogrel, prasugrel, and ticagrelor, and provides a practical guide to clinicians for determining which antiplatelet to use for patients with ACS.

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 undergoing PCI. Prasugrel is a novel thienopyridine antiplatelet agent recently approved for the treatment of patients with ACS undergoing PCI.

The enhanced platelet inhibition with prasugrel led to a reduction in major adverse cardiovascular events in patients with moderate to high risk ACS scheduled for PCI in the phase 3 TRITON-TIMI 38 trial. This benefit was seen more in patients suffering a STEMI and those with diabetes. However, this reduction in events was met with a significant increase in the risk of bleeding which overcame prasugrel's benefit in certain groups. Future studies with prasugrel are needed to determine its optimal utilization to minimize bleeding risks and evaluate its outcomes in ACS and safety profile in special patient populations.
