Assessment of Activity Levels for CYP2D6*1, CYP2D6*2, and CYP2D6*41 Genes by Population Pharmacokinetics of Dextromethorphan [PDF]

open access: yesClinical Pharmacology & Therapeutics, 2010
The pharmacokinetics of dextromethorphan (DM) is markedly influenced by cytochrome P450 2D6 (CYP2D6) enzyme polymorphisms. The aim of this study was to quantify the effects of the CYP2D6*1, *2, and *41 variants on DM metabolism in vivo and to identify other sources of pharmacokinetic variability.

Interrogation of CYP2D6 Structural Variant Alleles Improves the Correlation Between CYP2D6 Genotype and CYP2D6‐Mediated Metabolic Activity [PDF]

open access: yesClinical and Translational Science, 2020
The cytochrome P450 2D6 (CYP2D6) gene locus is challenging to accurately genotype due to numerous single nucleotide variants and complex structural variation.

CYP2D6 Phenotyping Using Urine, Plasma, and Saliva Metabolic Ratios to Assess the Impact of CYP2D6∗10 on Interindividual Variation in a Chinese Population [PDF]

open access: yesFrontiers in Pharmacology, 2017
Purpose: Asian populations have around 40–60% frequency of reduced function allele CYP2D6∗10 compared to 1–2% in Caucasian populations. The wide range of CYP2D6 enzyme activities in subjects with the CYP2D6∗10 variant is a big concern for clinical ...

Induction of CYP2D6 in pregnancy*

open access: yesClinical Pharmacology & Therapeutics, 1997
Expression of the drug-metabolizing enzyme cytochrome P4502D6 (CYP2D6) is predominantly under genetic control, and enzyme-inducing drugs have little influence on its activity. We studied the activity of CYP2D6 during pregnancy. One hundred forty pregnant women were genotyped for CYP2D6.

In vitro comparative analysis of metabolic capabilities and inhibitory profiles of selected CYP2D6 alleles on tramadol metabolism

open access: yesClinical and Translational Science
Tramadol, the 41st most prescribed drug in the United States in 2021 is a prodrug activated by CYP2D6, which is highly polymorphic. Previous studies showed enzyme‐inhibitor affinity varied between different CYP2D6 allelic variants with dextromethorphan ...

Development of a CYP2D6-enhanced HepaRG cell model with improved CYP2D6 metabolic capacity.

open access: yesPLoS ONE
Drug-induced liver injury is a major concern in drug development, and the limitations of animal models have driven interest in human-derived in vitro models for toxicity assessment.

Metoclopramide is metabolized by CYP2D6 and is a reversible inhibitor, but not inactivator, of CYP2D6 [PDF]

open access: yesXenobiotica, 2013
1. Metoclopramide is a widely used clinical drug in a variety of medical settings with rare acute dystonic events reported. The aim of this study was to assess a previous report of inactivation of CYP2D6 by metoclopramide, to determine the contribution of various CYPs to metoclopramide metabolism, and to identify the mono-oxygenated products of ...

Distinct Associations of Age and CYP2D6 Genotype With Parent Venlafaxine Exposure and O-Demethylation in Japanese Psychiatric Patients. [PDF]

open access: yesNeuropsychopharmacol Rep
This TDM study suggests that, in Japanese psychiatric patients receiving venlafaxine, age is associated with dose‐corrected parent‐drug exposure, whereas CYP2D6 genotype predominantly determines the ODV/VEN metabolic ratio. ABSTRACT Background Venlafaxine (VEN) is converted to O‐desmethylvenlafaxine (ODV) mainly through CYP2D6‐mediated O‐demethylation.

Expression of Human CYP2D6 in Artificial Cells Based on Polymer-Lipid Hybrid Vesicles. [PDF]

open access: yesChembiochem
Expression of eGFP and human cytochrome P450 2D6 (CYP2D6) within the lumen of giant polymer‐lipid hybrid vesicles using a Leishmania tarentolae‐based cell‐free protein expression system is illustrated. Both proteins were expressed in the vesicle lumen, and low‐polymer‐content hybrid vesicles were the most suitable scaffolds for CYP2D6 expression with ...

Is CYP2D6 phenotype predictable from CYP2D6 genotype? [PDF]

open access: yesMicrochemical Journal, 2018
Abstract Genetic polymorphism of cytochrome P450s results in clinically significant modifications in patients' drug metabolizing capacities. CYP2D6 has a crucial role in the elimination of several clinically important drugs (antiarrhythmics, beta-adrenergic blockers, psychopharmacons and analgesics); however, the prediction of the phenotypic ...
