DEVELOPMENT AND VALIDATION OF SIMULTANEOUS ASSAY OF SUBSTRATES-MARKERS OF MAIN CYTOCHROME P450 ISOFORMS AND THEIR METABOLITES USING HPLC-MS/MS

open access: yesРазработка и регистрация лекарственных средств, 2019
Simultaneous quantification method of assaying main CYP isoforms substrates-markers and their metabolites in urine using HPLC-MS/MS was developed to determine activity of following isoforms: caffeine/paraxanthine for CYP1A2, losartane/E-3174 for CYP2C9 ...

Polymorphic drug metabolising enzymes:Assessment of activities by phenotyping and genotyping in clinical pharmacology [PDF]

open access: yes, 2001
Drug effects (pharmacodynamics) are determined by drug concentration at target site and the affinity of the drug for a target. Pharmacogenetics describes inherited differences in drug metabolising enzyme activities and differences in drug transporters ...

The role of CYP2D6 in the metabolism of antidepressants

open access: yesGSC Biological and Pharmaceutical Sciences
The cytochrome P450 2D6 plays an important role in the metabolism of several drugs, including antidepressants, and it also influences their efficacy and adverse effects. Some of the CYP2D6 genetic variants are closely related with a different metabolism way, depending on its type (PM, MI, normal, UM); that impacts mostly reducing the pharmacologic ...

Comparison of Regression and Categorical Analysis for Pharmacokinetic Data From Renal Impairment Studies

open access: yesClinical Pharmacology &Therapeutics, Volume 118, Issue 4, Page 885-893, October 2025.
The US Food and Drug Administration 2024 guidance prefers regression analysis over categorical analysis for pharmacokinetic data for studies that assess pharmacokinetics in patients with impaired renal functions. The objective of this study was to compare these two statistical methods for pharmacokinetic data analysis of renal impairment studies ...

Impact of First‐of‐Its‐Kind Patient‐Facing Pharmacogenetics Tool on Dosing Decisions and Treatment Outcomes

open access: yesClinical Pharmacology &Therapeutics, Volume 118, Issue 4, Page 906-916, October 2025.
Germline pharmacogenetics (PGx) is increasingly used to tailor medication selection/dosing. However, existing systems primarily communicate PGx results to providers, limiting direct patient engagement. To address this, we developed YourPGx Oncology, an innovative patient‐facing portal that delivers multi‐gene PGx results (CYP2D6, UGT1A1, DPYD) through ...

Influence of cytochrome P450 2D6*10/*10 genotype on the risk for tramadol associated adverse effects: a retrospective cohort study

open access: yesFrontiers in Pharmacology
Background: Tramadol is primarily metabolized by the highly polymorphic CYP2D6 enzyme, leading to a large spectrum of adverse events and clinical response.

Pharmacogenetic Implementation Studies—Lessons Learned From the PREPARE Study

open access: yesClinical Pharmacology &Therapeutics, Volume 118, Issue 4, Page 803-812, October 2025.
The Ubiquitous Pharmacogenomics consortium (www.upgx.eu) has recently completed and published the Preemptive Pharmacogenomic Testing for Preventing Adverse Drug Reactions (PREPARE) study on the implementation of panel‐based pharmacogenetic testing. PREPARE has provided interesting lessons for the design, execution, and interpretation of future clinical

Prospective assessment of CYP2D6 by genotyping, phenotyping and measurement of tamoxifen, PD 05-09 4-hydroxy-tamoxifen and endoxifen in breast cancer patients treated with tamoxifen. [PDF]

open access: yes, 2010
Tamoxifen (tam) is a widely used endocrine therapy in the treatment of early and advanced stage breast cancer in women and men. It is a pro-drug having weak affinity with the estrogen receptor and needs to be converted to its main metabolite, endoxifen ...
