PHARMACOGENETICS OF ANTITHROMBOTIC DRUGS: STATUS UPDATE ON THE PROBLEM

Abstract

The review deals with the main trials devoted to the study of genetic markers of individual variability in drug response to antithrombotic agents. The first part describes the studies of the genes encoding the platelet receptor subunits studied in the association of the possible insufficient effect of acetylsalicylic acid, and transporter proteins and allelic variants with reduced CYP450 functional activity, which are associated with insufficient effect on clopidogrel therapy. The second part considers polymorphisms that determine the individual dose and the risk of bleeding due to excessive hypocoagulation in patients taking warfarin. It also presents current data on the study of genetically determined individual reactions to the new inhibitors: P2Y12 inhibitors (prasugrel and ticagrelor) and direct oral anticoagulants.
