Quickly find freely available drug and population models in our PBPK model repository.
The models provided have been collated from published examples which authors have shared in our Published Model Collection or developed as part of various global health projects in our Global Health Collection. This search facility searches both model collections simultaneously.

The Budesonide compound file was evaluated in a Crohn’s Disease (CD) population (PMID: 37765205) and two workspaces are supplied to recover the pharmacokinetic profiles published by Ludin et al. in 2001 and Wilson et al., 2017. The Crohn’s disease population is based on the population presented in PMID: 36056298 (link). A third workspace recovers the clinical profile for Budesonide in a healthy volunteer population (Edsbäcker et al., 2004).

For curcumin, the Japanese population library file from the Simcyp Human Simulator was used, and a sulfotransferase clearance pathway was incorporated as published for the curcumin PBPK model (Physiologically-Based Pharmacokinetic Predictions of the Effect of Curcumin on Metabolism of Imatinib and Bosutinib: In Vitro and In Vivo Disconnect - PubMed (nih.gov)). The curcumin model used in the publication linked is also based on this earlier published model. Fugut=1 represents worst-case scenario DDI while Fugut=0.03 represents assumption that fu,gut = fu,whole blood.
