Advances in the Clinical Use of Clopidogrel: A Review of Individualized Treatment Strategies and Monitoring Optimization Based on Genetic Polymorphisms.

This paper systematically reviews recent advances in clopidogrel clinical applications to optimize therapeutic precision and medication safety. Using a literature review methodology, we elucidate clopidogrel's pharmacokinetic properties and pharmacodynamic mechanisms, while evaluating its clinical efficacy and adverse reactions in disease management. Recent studies have emphasized the key role of genetic polymorphisms in regulating the efficacy and safety of clopidogrel. Polymorphisms in the gene have a significant effect on the metabolism of clopidogrel, with loss-of-function (LOF) alleles () reducing the production of active metabolites, leading to elevated platelet reactivity and increasing the risk of major adverse cardiovascular events (MACE), particularly in the Asian populations, where the prevalence of LoF alleles is as high as 29-35%. In contrast, the gain-of-function allele results in a reduced risk of cardiovascular events but increases the risk of bleeding. This article summarizes the latest research progress and monitoring methods of clopidogrel, and suggests that clinics should combine genotyping and platelet function testing with monitoring of blood levels to optimize treatment and provide data reference for clinical administration of clopidogrel.
