Whole Body Physiologically-based Pharmacokinetic (PBPK) model
This document presents a SimBiology® model of a generic whole - body physiologically - based pharmacokinetic (WB - PBPK) model as described in the article “Evaluation of a generic physiologically based pharmacokinet ic model for lineshape analysis” by Sheila Annie Peters 
The generic PBPK model presented here was originally developed by Sheila Annie Peters and used for lineshape analysis, to investigate clinical PK data by exploring the effects of additional or alternative absorption, distribution, metabolism, and excretion ( ADME ) pathways. The model includes an expanded version of the compartmental absorption and transit (CAT) model of gastrointestinal absorption, additionally including enterohepatic recycling, gut wall metabolism, and paracellular absorption. Tissue partition coefficients are calculated according to equations presented by Rodgers et al . Drug parameters describing Atenolol and Captopril ADME are included as variants. Other variants packaged with this SimBiology project file describe Human fasted, Human fed and Rat physiologies and allow easy scale - up from Rat PK to Human PK. More information on the use of this model can be found in the Description section of the Model tab.
