Clinical role of CYP2C19 polymorphisms in patients with congenital adrenal hyperplasia due to 21-hydroxylase deficiency

Acta Chimica Slovenica, 2016
Extraadrenal enzymes such as CYP2C19 may participate in residual 21-hydroxylation of progesterone leading to milder phenotypes of congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21OHD). Among 94 21OHD patients 28 were homozygous or

The quantitative impact of metabolism‐inhibiting drugs on the occurrence of adverse drug reactions—A backward selection approach

British Journal of Clinical Pharmacology, EarlyView.
Abstract Aim The quantitative effect of several inhibitory drugs on the development of adverse drug reactions (ADRs) is currently difficult to estimate. Our aim was to identify metabolic pathways, which, when inhibited, increase the risk for certain ADRs, and to use this system to consider comedication at individual level. Methods Data of a prospective

The influence of the CYP2C19*10 allele on clopidogrel activation and CYP2C19*2 genotyping [PDF]

Pharmacogenetics and Genomics, 2014
The polymorphic hepatic enzyme CYP2C19 catalyzes the metabolism of clinically important drugs such as clopidogrel, proton-pump inhibitors, and others and clinical pharmacogenetic testing for clopidogrel is increasingly common. The CYP2C19*10 single-nucleotide polymorphism (SNP) is located 1 bp upstream the CYP2C19*2 SNP.

Inflammation‐driven variability in drug metabolism: Insights from voriconazole treatment of HSCT recipients

British Journal of Clinical Pharmacology, EarlyView.
Aims Voriconazole is commonly used to prevent fungal infections after haematopoietic stem cell transplantation (HSCT). Although its metabolism is influenced by CYP2C19 genetics and inflammation, their combined effect is rarely considered in clinical practice, and integrated analyses remain limited.

Association of CYP2C19*2 polymorphisms and high on-treatment platelet reactivity in acute myocardial infarction or coronary artery in-stent restenosis patients during dual antiplatelet therapy

Medicine in Drug Discovery, 2020
Objective: Cytochrome CYP2C19 mutant allele is associated with high on-treatment platelet reactivity (HTPR) after standard clopidogrel treatment, which is accompanied by an increased risk of ischemic events. This study assesses the association of CYP2C19

Prognostic Implication of CYP2C19 Genotype According to Clinical Risk Stratification After Drug‐Eluting Stent Implantation

Clinical Pharmacology &Therapeutics, EarlyView.
From the nationwide multicenter consortium, 8,163 patients undergoing drug‐eluting stent implantation were classified according to the presence of the CYP2C19 loss‐of‐function (LoF) allele: rapid or normal metabolizers (RMs/NMs) vs. intermediate or poor metabolizers (IMs/PMs), and clinical risk was stratified using the CHADS‐P2A2RC and TRS 2°P scores ...

Effect of co-administered inducer or inhibitor on omeprazole pharmacokinetics based on CYP2C19 genotype

Journal of Pharmacological Sciences, 2019
Polymorphisms of cytochrome P450 (CYP) enzymes can affect enzymatic activity, drug metabolism and drug interactions. Although the potential for drug interactions is especially important when co-administering drugs with strong inductive or inhibitory ...

Repeated Intake of Grapefruit Juice Inhibits CYP2B6, CYP2C9, CYP2C19, and CYP3A4 while Lingonberry Powder Does Not Induce Major CYP Enzymes in Humans

Clinical Pharmacology &Therapeutics, EarlyView.
Grapefruit juice is a well‐established inhibitor of cytochrome P450 (CYP) 3A4, but its effects on other CYP enzymes or organic anion transporting polypeptides (OATPs) are not fully characterized in humans. Recently, lingonberry powder was shown to induce murine CYP enzymes. We investigated the effects of lingonberry powder and grapefruit juice on seven

Frequencies of two CYP2C19 defective alleles (CYP2C19*2, and *3) among Iranian population in Mazandaran Province

Research in Molecular Medicine, 2013
Background: Cytochrome P450 2C19 (CYP2C19) is a polymorphically expressed enzyme that shows marked interindividual and interethnic variation. CYP2C19*2 and CYP2C19*3 are the most frequently identified defective alleles in Orientals and Caucasian poor ...
