Pharmacoeconomic analysis of personalized antiplatelet therapy in patients with acute coronary syndromer

Relevance. The problem of antiplatelet therapy resistance is not fully solved, whereas its manifestations in the form of stent thrombosis cause a negative contribution in treatment and can lead to significant economic damage to the healthcare system. Pharmacogenetic testing as a personalization tool can potentially reduce the cost of treatment, which requires pharmacoeconomic research of pharmacogenetic methods. The aim of this study was a pharmacoeconomic evaluation of the pharmacogenetic testing implementation before the antiplatelet therapy in patients with acute coronary syndrome after percutaneous coronary intervention. Methods. In our study, a decision tree model was built with a time horizon of 1 year and a cost-effectiveness analysis was performed for six compared treatment strategies in patients with acute coronary syndrome after stent implantation with and without genotyping for the drugs clopidogrel, ticagrelor and prasugrel. Results. A treatment strategy with pharmacogenetic testing and the choosing of prasugrel for slow and intermediate metabolizers was the most preferred with CER 35 577.40 rubles per 1 unit of effectiveness. The most expensive strategy was the “blind” use of ticagrelor for all patients. Conclusion. Based on the modeling results, it can be concluded that the implementation of pharmacogenetic testing before prescribing antiplatelet drugs in patients with acute coronary syndrome undergoing stenting can potentially reduce the incidence of adverse events such as stent thrombosis and reduce the overall cost of treatment.
