Warfarin Dosing in Patients With CYP2C9*5 Variant Alleles

Clinical Pharmacology & Therapeutics

Kathryn J. Lindley, et al.


Pharmacogenetic dosing improves the accuracy of warfarin dosing, but current pharmacogenetic dosing algorithms are less accurate in populations of African ancestry. The cytochrome P450 2C9*5 (CYP2C9*5) allele is found almost exclusively in populations of African ancestry, and in vitro studies suggest CYP2C9*5 is associated with reduced clearance of warfarin.

Clinical Pharmacogenetics Implementation Consortium Guideline for CYP2C19 Genotype and Clopidogrel Therapy: 2022 Update

Clinical Pharmacology & Therapeutics

Craig R. Lee, et al.


CYP2C19 catalyzes the bioactivation of the antiplatelet prodrug clopidogrel, and CYP2C19 genotype impacts clopidogrel active metabolite formation. CYP2C19 intermediate and poor metabolizers who receive clopidogrel experience reduced platelet inhibition and increased risk for major adverse cardiovascular and cerebrovascular events.

A hybrid implementation-effectiveness randomized trial of CYP2D6-guided postoperative pain management

Genetics in Medicine

Cameron D. Thomas, et al.


Cytochrome P450 2D6 (CYP2D6) genotype–guided opioid prescribing is limited. The purpose of this type 2 hybrid implementation-effectiveness trial was to evaluate the feasibility of clinically implementing CYP2D6-guided postsurgical pain management and determine that such an approach did not worsen pain control.
