Standard Clopidogrel Versus Prasugrel Low Dose Therapy in Elderly Patients With Acute Coronary Syndrome (RESET ELDERLY)

January 24, 2013 updated by: Gennaro Sardella

PhaRmacodynamic Effect of Antiplatelet Agents in Elderly Patients: Standard Clopidogrel Versus prasugrEl Low Dose Therapy.

The elderly represent a growing segment of the coronary population treated by dual antiplatelet therapy for percutaneous coronary intervention (PCI). These patients bear a higher risk of both ischemic events and bleeding complications than younger patients, with a subsequently higher rate of mortality.Recentprogress in antithrombotic treatment demonstrated the efficacy of adding a P2Y12 receptor antagonist to low-dose aspirin. Whether this benefit is also present in the elderly remains a debated issue due to the lack of specific data in this sub-population. The present study was realized to provide specific data on platelet response to clopidogrel, standard dose (75 mg) or prasugrel 5 mg in elderly patients (≥75 years old) whereas the superiority in PR response of the latter should allows the Prasugrel therapy in elderly patients with the better clinical efficacy and therapeutical safety already showed compared with Clopidogrel.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Prasugrel low dose
Patient will be randomized to this intervention will receive prasugrel 5 mg and after 15 days and 30 days we will control the responsivness of the study drug.
Drug: Prasugrel
Patient will be randomized to this intervention will receive the low dose of prasugrel and after 15 days and 30 days we will control the responsivness of the study drug.
Experimental: Clopidogrel standard dose
Patient will be randomized to this intervention will receive clopidogrel 75 mg and after 15 days and 30 days we will control the responsivness of the study drug.
Drug: Clopidogrel
Patient will be randomized to this intervention will receive the standard dose of clopidogrel and after 15 days and 30 days we will control the responsivness of the study drug.
