Managing Drug-Drug Interactions Involving the Non-Prescription Opioid Loperamide Through Physiologically Based Pharmacokinetic Modeling. [PDF]

CPT Pharmacometrics Syst Pharmacol
ABSTRACT Loperamide is a widely used nonprescription peripherally acting opioid indicated for diarrhea. Loperamide undergoes extensive first‐pass metabolism, primarily by cytochrome (CYP) 3A and CYP2C8, with minor contributions from CYP2B6 and CYP2D6, and intestinal efflux by P‐glycoprotein (P‐gp).

Strategy for Identifying Rational Sensitivity Analysis Using PBPK Modeling for Precipitant Drug-Drug Interaction Predictions. [PDF]

Clin Pharmacol Ther
Physiology Based Pharmacokinetic (PBPK) modeling is an established essential tool for predicting and/or analyzing drug–drug interactions (DDI). Uncertainty and variability associated with in vitro determined DDI‐related parameters have often been considered a limitation for predicting PBPK‐DDIs.

Albumin Levels Are Predictive of Cachexia-Induced Time-Dependent Clearance of Therapeutic Antibodies: A Physiologically Based Pharmacokinetic Model of Durvalumab. [PDF]

CPT Pharmacometrics Syst Pharmacol
ABSTRACT Cachexia is a metabolic condition that accelerates the clearance of monoclonal antibodies in cancer patients and is a known mechanism causing time‐dependent clearance. Successful anticancer treatment often ameliorates symptoms of cachexia, reducing the drug clearance over time especially in patients who respond. Serum albumin level is a common

Validating Physiologically-Based Pharmacokinetic Models Using the Continuous Ranked Probability Score: Beyond Being Correct on Average. [PDF]

CPT Pharmacometrics Syst Pharmacol
ABSTRACT Physiologically‐based pharmacokinetic (PBPK) models have become increasingly popular for model‐informed drug development (MIDD) over the past decade. While several guidelines for model evaluation exist, these are by design often of a general and non‐specific nature. It is clear what steps should be carried out but not necessarily how.

Evaluating the Impact of Intestinal Bile Salts on Drug Absorption Using PBPK Modeling: Case Studies With Efavirenz, Cinnarizine, and Posaconazole. [PDF]

CPT Pharmacometrics Syst Pharmacol
ABSTRACT A high number of poorly soluble compounds are being developed; thus, understanding the factors that influence their absorption is critical. Intestinal bile salts, which facilitate micelle‐mediated solubilization, are particularly important for drugs with low solubility and are reported to be highly variable.

Population variability in animal health: Influence on dose-exposure-response relationships: Part II: Modelling and simulation [PDF]

, 2018
During the 2017 Biennial meeting, the American Academy of Veterinary Pharmacology and Therapeutics hosted a 1‐day session on the influence of population variability on dose‐exposure‐response relationships. In Part I, we highlighted some of the sources of

Applied Concepts in PBPK Modeling: How to Build a PBPK/PD Model [PDF]

CPT: Pharmacometrics & Systems Pharmacology, 2016
The aim of this tutorial is to introduce the fundamental concepts of physiologically based pharmacokinetic/pharmacodynamic (PBPK/PD) modeling with a special focus on their practical implementation in a typical PBPK model building workflow. To illustrate basic steps in PBPK model building, a PBPK model for ciprofloxacin will be constructed and coupled ...

Physiologically Based Pharmacokinetic Modelling for Nicotine and Cotinine Clearance in Pregnant Women

Frontiers in Pharmacology, 2021
Introduction: Physiologically based pharmacokinetic (PBPK) models for the absorption, disposition, metabolism and excretion (ADME) of nicotine and its major metabolite cotinine in pregnant women (p-PBPK) are rare. The aim of this short research report is

A Mechanistic Physiologically-Based Biopharmaceutics Modeling (PBBM) Approach to Assess the In Vivo Performance of an Orally Administered Drug Product: From IVIVC to IVIVP

Pharmaceutics, 2020
The application of in silico modeling to predict the in vivo outcome of an oral drug product is gaining a lot of interest. Fully relying on these models as a surrogate tool requires continuous optimization and validation.
