The relation between inflammatory biomarkers and drug pharmacokinetics in the critically ill patients: a scoping review.

Background: The level of inflammation alters drug pharmacokinetics (PK) in critically ill patients. This might compromise treatment efficacy. Understanding the specific effects of inflammation, measured by biomarkers, on drug absorption, distribution, metabolism, and excretion is might help in optimizing dosing strategies.

Towards optimization of dexamethasone therapy in the maintenance phase of pediatric acute lymphoblastic leukemia: A population pharmacokinetic and pharmacodynamic study of dexamethasone and metabolite.

Dexamethasone is crucial in pediatric acute lymphoblastic leukemia (ALL) treatment, however, studies regarding the pharmacokinetics of dexamethasone and its metabolites are scarce. Our study conducted a comprehensive pharmacokinetic-pharmacodynamic analysis of dexamethasone and metabolite, examining their association with dexamethasone-induced toxicity. Peak and trough concentrations were collected during the maintenance phase from pediatric ALL patients who received oral dexamethasone (6mg/m2/day).

Selecting the Best Pharmacokinetic Models for a Priori Model-Informed Precision Dosing with Model Ensembling.

Background And Objective: When utilizing population pharmacokinetic (popPK) models for a priori dosage individualization, selecting the best model is crucial to obtain adequate doses. We developed and evaluated several model-selection and ensembling methods, using external evaluation on the basis of therapeutic drug monitoring (TDM) samples to identify the best (set of) models per patient for a priori dosage individualization.

Methods: PK data and models describing both hospitalized patients (n = 134) receiving continuous vancomycin (26 models) and patients (n = 92) receiving imatinib in an outpatient setting (12 models) are included.

Clinical implications of nintedanib pharmacokinetics in patients with pulmonary fibrosis.

Background: Nintedanib is used to treat both idiopathic and progressive pulmonary fibrosis (IPF/PPF). Evidence of both an exposure-response relationship and an exposure-toxicity relationship has been found, suggesting the potential value of therapeutic drug monitoring (TDM). We aimed to define the therapeutic window of nintedanib in a real-world cohort.
