Search the PBPK Model Repository

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.

Pitavastatin_V17R1_ASTAR_20190730
The submitted compound file for Pitavastatin uses ADAM, Full PBPK method 2, enzyme kinetics for metabolism and transporter kinetics for intestinal absorption, permeability limited liver model and MechKiM model. Tissue : Plasma partition coefficients have been modified to include data obtained from rat distribution studies. It has been used together with the unmodified Sim-Healthy Volunteer library file. https://www.altex.org/index.php/altex/article/view/1215
Hydroxychloroquine_V18R1_PekingUniversityThirdHospital_20200323
The HCQ file was developed by Peking University Third Hospital and kindly shared on our Members Area. Please cite the original reference in which the file was presented (see link to publication) and please share your simulation results ASAP. Considering the current public health situation, we are happy to coordinate the simulation efforts around this PBPK model. The submitted compound file for HCQ is using first order absorption model, full-PBPK, Method 2. Perfusion limited lung model was developed. Additional organ was defined as lung and changed the tissue blood rate flow as 0.2. Clearance of HLM was estimated based on fm. It has been verified with a Caucasian healthy volunteer population library that was unmodified from the Sim-Healthy Volunteer library file. Please note a custom dosing for 5 days has been included in the file. https://pubmed.ncbi.nlm.nih.gov/32150618/
Cefuroxime_V12R1_FDA_20150709
Table 1 of main paper and further discussion in supplemental file. IV only. Key feature is the use of mechanistic kidney model to simulate the effect of severe renal impairment and probenecid inhibition.

 The model at-a-glance

Absorption Model

  • First-Order

Volume of Distribution 

  • Full PBPK (Method 2)

Routes of Elimination

  • 89% MAO (entered using ‘user-UGT’ as a surrogate in the Simulator), 11% CYP2D6

Perpetrator DDI

  • CYP1A2 Inhibitor (in vitro)

Validation

  •  6 studies with single (15 to 45 mg) and multiple (15 mg QD) dosing. 100% of Cmax and AUC values within 1.5-fold.
  • No clinical DDI studies to verify contribution of metabolic routes

Limitations

  •  The active metabolites of primaquine have not characterized due to their instability. Therefore, a PBPK model for active metabolites cannot be developed in their own right.
  • Qualitative data suggests a role of P-gp, however, Jmax and Km values have not been measured.
  • There is evidence of enantiomer specific metabolism for primaquine which has not been considered in the current model.

Updates in Version 19

  • Updated in vitro protein and blood binding data and subsequent back calculation of CLint (retrograde approach)
    •  fu: 0.19 -> 0.26
    • B:P: 1 -> 0.82
  • Converted from minimal PBPK model to full PBPK model
