Purpose of the study was to develop a PBPK model for amoxicillin incorporating saturable transport processes affecting the drug’s absorption and distribution.
PBPK Modeling of Erythromycin Absorption and Disposition Mediated by Transporters in Humans
Erythromycin, a macrolide antibiotic, is cleared primarily by cytochrome P450-3A4 metabolism. Its uptake into enterocytes and hepatocytes is mediated by organic anion transporter (OAT) and organic anion…

The Use of Modeling Tools to Drive Efficient Oral Product Design
Modeling and simulation of drug dissolution and oral absorption has been increasingly used over the last decade to understand drug behavior in vivo based on the physicochemical properties of Active...
Preclinical Assessment of the Absorption and Disposition of the Phosphatidylinositol 3-Kinase/Mammalian Target of Rapamycin Inhibitor GDC-0980 and Prediction of Its Pharmacokinetics and Efficacy in Human
The objectives of these studies were to characterize the absorption and disposition of GDC-0980 and assess its efficacy in an MCF7-neo/HER2 human breast cancer xenograft model in immunocompromised mice.
Application of PBPK modeling to predict human intestinal metabolism of CYP3A substrates – An evaluation and case study using GastroPlus™
First pass metabolism in the intestinal mucosa is a determinant of oral bioavailability of CYP3A substrates and so the prediction of intestinal availability (Fg) of potential drug candidates is important.
Comparison of in vitro–in vivo release of Risperdal® Consta® microspheres
The objective was to investigate the relationship between in vitro and in vivo release of commercial Risperdal® Consta® microspheres.
Regioselective oxidation of phospho-NSAIDs by human cytochrome P450 and flavin monooxygenase isoforms: implications for their pharmacokinetic properties and safety
Phospho-ibuprofen (MDC-917) and phospho-sulindac (OXT-328) are highly effective in cancer and arthritis treatment in preclinical models. Here, we investigated their metabolism by...
Predicting feasibility and characterizing performance of extended-release formulations using physiologically based pharmacokinetic modeling
This review presents nine case studies where physiologically based pharmacokinetic modeling has been used in the design and development of extended-release formulations.
Enhanced evaluation of selective androgen receptor modulators in vivo
Selective androgen receptor modulators (SARMs) are a class of drugs that control the activity of the androgen receptor (AR), which mediates the response to androgens, in a...
An analysis of N-acetylcysteine treatment for acetaminophen overdose using a systems model of drug-induced liver injury
N-acetylcysteine (NAC) is the treatment of choice for acetaminophen poisoning; standard 72-h oral or 21-h intravenous protocols are most frequently used.
Human apolipoprotein E peptides inhibit hepatitis C virus entry by blocking virus binding
Hepatitis C virus (HCV) entry is a multiple-step process involving a number of host factors and hence represents a promising target for new antiviral drug development.
Translation of drug effects from experimental models of neuropathic pain and analgesia to humans
Neuropathic pain research remains a challenging undertaking owing to: (i) the lack of understanding about the underlying disease processes; and (ii) poor...
Prediction of acute mammalian toxicity using QSAR methods: a case study of sulfur mustard and its breakdown products
Predicting toxicity quantitatively, using Quantitative Structure Activity Relationships (QSAR), has matured over recent years to the point that the predictions can be used to help identify missing comparison...
