Plasma 4β‐hydroxycholesterol (4β‐OHC) normalized for the levels of its parent cholesterol (4β‐OHC/C) is an endogenous biomarker for hepatic CYP3A4. This study evaluated CYP3A4 activity longitudinally in individuals while their obesity status was changing. 4β‐OHC/C was measured pre‐surgery (n = 54) and 2 years after Roux‐en‐Y gastric bypass (n = 30) and

From Executor to Orchestrator: The Pharmacology Scientist in the Age of Agentic AI
Drug development productivity has not improved despite five decades of computational advancement, with the probability that a compound entering Phase I achieving regulatory approval remaining near 10%. Each automation wave increased throughput while leaving the interpretive bottleneck intact; scientists continued to formulate questions, evaluate ...

Codeine and Metabolite Concentrations in the Breastfed Neonate
ABSTRACT Analgesic effect from codeine is from its metabolite, morphine. Morphine is formed by the O‐demethylation of codeine and that enzyme is controlled by the cytochrome P450 2D6. More than 60 alleles in the CYP2D6 gene have been identified. This spectrum of polymorphism can be categorized into four groups: poor (PM), intermediate (IM), normal (NM),

ABSTRACT Background Intravenous lidocaine therapy (IVLT) is often used in perioperative multimodal analgesia due to its analgesic, anti‐hyperalgesic, and anti‐inflammatory effects. In adults, IVLT doses of 1–2 mg/kg/h produce plasma concentrations of 1–2 μg/mL, within the presumed therapeutic range of 1–5 μg/mL.

ABSTRACT Reliable physiologically based pharmacokinetic (PBPK) modeling depends on tissue‐specific expression profiles that reflect protein activities governing drug disposition. In PK‐Sim, existing expression databases rely on transcriptomics data. However, mRNA levels often exhibit limited correlation with protein abundance, frequently necessitating ...

Introduction to Single‐Cell Physiologically‐Based Pharmacokinetic (scPBPK) Models
ABSTRACT The current investigation introduces single‐cell physiologically based pharmacokinetic (scPBPK) models to gain insight into drug disposition at the cellular scale. The transition from standard PBPK (sPBPK) models to scPBPK models required depiction of expression‐dependent (ED) processes, such as drug metabolism or membrane transport.

Integrated PBPK modelling for PFOA exposure and risk assessment
Per- and polyfluoroalkyl substances (PFASs) pose significant public health concerns due to their environmental persistence, bioaccumulation, and ubiquitous presence in human biomonitoring (HBM) data, despite regulatory restrictions. This study establishes a deterministic pharmacokinetic model for perfluorooctanoic acid (PFOA), enabling the estimation ...

Aim To develop and validate a physiologically‐based pharmacokinetic (PBPK) model enabling inhaled oxytocin dose selection for clinical evaluation. Subsequently, to conduct a phase 1 study investigating the pharmacokinetics and safety of selected doses of an optimized inhaled oxytocin product in healthy, non‐pregnant female participants.
