Effectiveness and Safety Comparison of P2y12 Receptor Inhibitors in Patients With Invasive Strategy for Acute Coronary Syndrome

Dual antiplatelet therapy (DAPT) using of acetylsalicylic acid and antagonists of platelet’s P2Y12 receptors is included in standards for treatment of patients with acute coronary syndrome (ACS) who underwent percutaneous coronary intervention (PCI). Clopidogrel, prasugrel, and ticagrelor are the P2Y12 receptor inhibitors used as a component of DAPT. The aim of this review is to determine the most effective and the safest P2Y12 receptor inhibitor for treating patients with an invasive treatment strategy of ACS. The TRITON study compared clopidogrel and pragugrel efficacy and safety had demonstrated a significantly higher efficiency in reducing the risk of reaching the primary endpoint (including cardiovascular death, myocardial infarction and stroke) for prasugrel, but at the same time, the prasugrel group was reliably recorded higher rate of major bleeding. Comparison of the efficacy and safety of clopidogrel and ticagrelor was carried out in the PLATO study, where ticagrelor was shown to be more effective in reducing cardiovascular deaths and myocardial infarction, while the safety of the drugs was comparable. A subsequent ISAR-REACT 5 study proved higher efficacy of prasugrel compared to ticagrelor in reducing the risk of reaching a primary endpoint with comparable safety to the major bleeding risk. Baseline data represents that the most effective drug among P2Y12 receptor inhibitors as a component of DAPT for patients with an invasive treatment strategy is prasugrel, and the safest is clopidogrel, which can be considered in elderly patients.
