Frequencies of Defective CYP2C19 Alleles in a Hong Kong Chinese Population: Detection of the Rare Allele CYP2C19*4 [PDF]

open access: yesClinical Chemistry, 1999
A genetic polymorphism in the metabolism of the anticonvulsant drug mephenytoin in humans is a prime example of interracial and individual variability in drug metabolism. This polymorphism affects the metabolism of several other clinically used drugs, some of which are of interest in psychopharmacotherapy (1).

Impact of CYP2C19 Genotype on Escitalopram Exposure and Therapeutic Failure: A Retrospective Study Based on 2,087 Patients.

open access: yesAmerican Journal of Psychiatry, 2018
OBJECTIVE The antidepressant escitalopram is predominantly metabolized by the polymorphic CYP2C19 enzyme. The authors investigated the effect of CYP2C19 genotype on exposure and therapeutic failure of escitalopram in a large patient population.

CYP2C9 and CYP2C19: Deep Mutational Scanning and Functional Characterization of Genomic Missense Variants

open access: yesClinical and Translational Science, 2020
Single nucleotide variants in the open reading frames (ORFs) of pharmacogenes are important causes of interindividual variability in drug response. The functional characterization of variants of unknown significance within ORFs remains a major challenge ...

Investigation of a broad‐spectrum micronutrient formulation as a possible precipitant of pharmacokinetic micronutrient–drug interactions

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aims Daily broad‐spectrum micronutrients are being used by the general public and formulations are receiving research interest in mental health settings. Despite concerns about combining medicines and broad‐spectrum micronutrients in mental health care, there have not been any formal evaluations of potential interactions.

CYP2C19 genetic polymorphism in the Vietnamese population

open access: yesAnnals of Human Biology, 2019
Background: Genetic polymorphism of CYP2C19 has been shown to affect enzyme activity and thereby contribute to inter-individual variability in drug metabolism and response.

Polymorphisms of MDR1, CYP2C19 and P2Y12 genes in Indian population: Effects on clopidogrel response

open access: yesIndian Heart Journal, 2013
Aims/objective: Influence of genetic variations on the response of clopidogrel, an antiplatelet drug is implicated. In the present study, the prevalence of single nucleotide polymorphisms of MDR1 (C3435T), CYP2C19 [CYP2C19*2 CYP2C19*3, CYP2C19*17] and ...

Frequencies of clinically important CYP2C19 and CYP2D6 alleles are graded across Europe

open access: yesEuropean Journal of Human Genetics, 2019
CYP2C19 and CYP2D6 are important drug-metabolizing enzymes that are involved in the metabolism of around 30% of all medications. Importantly, the corresponding genes are highly polymorphic and these genetic differences contribute to interindividual and ...

Prospective CYP2C19‐Guided Voriconazole Prophylaxis in Patients With Neutropenic Acute Myeloid Leukemia Reduces the Incidence of Subtherapeutic Antifungal Plasma Concentrations

open access: yesClinical pharmacology and therapy, 2020
A risk mitigation strategy was implemented to determine if a higher prophylactic voriconazole dosage in patients with CYP2C19 rapid metabolizer neutropenic acute myeloid leukemia (AML) reduces the incidence of subtherapeutic trough concentrations ...

Variability in intestinal drug metabolizing enzymes and transporters in Crohn's disease and potential impact on oral drug absorption

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aims The aim of study was to generate quantitative data on the abundance of drug‐metabolizing enzymes and transporters (DMETs) in inflamed and non‐inflamed Crohn's disease (CD) ileum and colon, for incorporation into physiologically based pharmacokinetic (PBPK) models, enabling prediction of oral drugs' pharmacokinetics (PK) perturbation in CD patients.
