Development of a physiologically‐based pharmacokinetic model for Ritonavir characterizing exposure and drug interaction potential at both acute and steady‐state conditions

open access: yesCPT: Pharmacometrics &Systems Pharmacology, Volume 14, Issue 3, Page 523-539, March 2025.
Abstract Ritonavir (RTV) is a potent CYP3A inhibitor that is widely used as a pharmacokinetic (PK) enhancer to increase exposure to select protease inhibitors. However, as a strong and complex perpetrator of CYP3A interactions, RTV can also enhance the exposure of other co‐administered CYP3A substrates, potentially causing toxicity.

A combined in vitro/in silico approach to identifying off-target receptor toxicity [PDF]

open access: yes, 2018
Many xenobiotics can bind to off-target receptors and cause toxicity via the dysregulation of downstream transcription factors. Identification of subsequent off-target toxicity in these chemicals has often required extensive chemical testing in animal ...

Disease–Drug–Drug Interaction of Imatinib in COVID‐19 ARDS: A Pooled Population Pharmacokinetic Analysis

open access: yesCPT: Pharmacometrics &Systems Pharmacology, Volume 14, Issue 3, Page 583-595, March 2025.
ABSTRACT Prior pharmacokinetic (PK) analysis revealed that increased alpha‐1‐acid glycoprotein (AAG) levels are associated with decreased imatinib unbound fraction in coronavirus disease 2019 (COVID‐19) patients. This study aimed to investigate the PK of total and unbound concentrations of imatinib and the metabolite N‐desmethyl imatinib in ...

Physiologically Based Pharmacokinetic (PBPK) Modeling to Predict CYP3A-Mediated Drug Interaction between Saxagliptin and Nicardipine: Bridging Rat-to-Human Extrapolation

open access: yesPharmaceutics
The aim of this study was to predict the cytochrome P450 3A (CYP3A)-mediated drug–drug interactions (DDIs) between saxagliptin and nicardipine using a physiologically based pharmacokinetic (PBPK) model.

Transforming Treatment: The Impact of Bariatric Surgery on Oral Drug Absorption

open access: yesObesity Reviews, EarlyView.
ABSTRACT Obesity represents a significant threat to global public health, with an estimated 16% of adults worldwide (2022) being classified as people with obesity, with a body mass index of 30 or more. Bariatric surgery is regarded as the most effective treatment option for people with obesity, with the three main types of bariatric surgery being ...

High-performance PBPK model for predicting CYP3A4 induction-mediated drug interactions: a refined and validated approach

open access: yesFrontiers in Pharmacology
IntroductionThe cytochrome P450 enzyme 3A4 (CYP3A4) mediates numerous drug-drug interactions (DDIs) by inducing the metabolism of co-administered drugs, which can result in reduced therapeutic efficacy or increased toxicity.
