Clinical Efficacy and Safety of Reduced-Dose Prasugrel versus Clopidogrel in Patients Undergoing Percutaneous Coronary Intervention: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

Objectives: This systematic review and meta-analysis of randomized controlled trials (RCTs) compared the clinical efficacy and safety of reduced-dose prasugrel (loading dose: 20 mg; daily maintenance dose: 3.75 mg) and clopidogrel in patients undergoing percutaneous coronary intervention (PCI).

Description
Summary:Objectives: This systematic review and meta-analysis of randomized controlled trials (RCTs) compared the clinical efficacy and safety of reduced-dose prasugrel (loading dose: 20 mg; daily maintenance dose: 3.75 mg) and clopidogrel in patients undergoing percutaneous coronary intervention (PCI). Methods: PubMed, Embase, and the Cochrane Library database were searched for relevant articles from inception to March 8, 2021. Only RCTs that compared the clinical efficacy and safety of reduced-dose prasugrel and clopidogrel treatment in adult patients undergoing PCI were included. The primary outcome was the risk of major cardiovascular events (MACEs). Results: Four RCTs involving 2464 patients were included. The overall risk of MACEs was 8.3% (102/1235) in the study group (reduced-dose prasugrel) and 9.8% (121/1229) in the control group (clopidogrel). No significant difference was observed in the risk of MACEs between the study and control groups (risk ratio: 0.84, 95% confidence interval: 0.65-1.08, I^2 = 0%). In addition, cardiovascular-related death, all-cause death, nonfatal myocardial infarction, nonfatal stroke, revascularization, and stent thrombosis did not differ significantly between the two groups. Apart from a higher risk of minor bleeding in the study group, reduced-dose prasugrel had a similar bleeding risk to clopidogrel. Conclusions: The clinical efficacy of reduced-dose prasugrel is comparable to that of clopidogrel; however, the risk of minor bleeding should be considered when prescribing this regimen for patients undergoing PCI.
