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.

Oseltamivir_Carboxylate_V15R1_USFDA_20170810
Model Files Publication
http://onlinelibrary.wiley.com/doi/10.1002/cpt.750/full OC model updated from Hsu 2014. Evaluation of the effect of renal impairment on the PK of OAT substrates. NOTE: logP -2.1 in the model. different from Table 1 (-2.4).
Search Score: 1
Dihydroartemisinin (DHA)
Model Files Publication

Brand Name(s) include: D-Artepp, Artekin, Diphos, TimeQuin, Eurartesim, Duocotecxin

Disease: Malaria

Drug Class: Antimalarials

Date Updated: March 2022

The model at-a-glance

  Absorption Model
  • First-Order

  Volume of Distribution

  • Full PBPK (Method 2)

Note: Kp scalar used

  Route of Elimination
  • UGT1A9 (50%); UGT2B7(50%)

  Perpetrator DDI
  • CYP1A2 Inhibitor

  Validation

  • Four clinical studies describing single dose exposure of DHA were used to verify the PBPK model.  100% of studies were within 2-fold, of which 75% were within 1.5-fold.  Thus, the model performance was deemed acceptable.

  Limitations
  • The model does not account for the differences in plasma fraction unbound observed in patients compared to healthy volunteers.
  • Verification needed for perpetrator DDI assessment as literature data is unavailable at this time.

  Updates in V19
  • Updated in vitro data
    • Propranolol Papp: 30 cm/s x 106
  • Converted model to full PBPK with Vss predicted through Method 2
  • Updated retrograde clearance

Azithromycin
Model Files Publication

Brand Name(s) include: Zithromax

Disease: Malaria

Drug Class: Marcolide Antibiotic

Date Updated: March 2021

The model at-a-glance

  Absorption Model
  • First-Order

  Volume of Distribution

  • Full PBPK (Method 2)

Note: A Kp scalar (0.04) was used in the model

  Route of Elimination
  • No metabolism; a biliary CLint was input based on clinical data

  Perpetrator DDI
  • None

  Validation

  • Two clinical studies describing single and multiple dose exposure of atovaquone were used to verify the PBPK model. 100% of studies were within 1.5-fold.

  Limitations
  • There are some data to suggest atovaquone is an inhibitor of BCRP.  This is currently not included within the model.

  Updates in V19
  • Updated in vitro­ data
    • LogP: 5.8 -> 8.4
    • Caco-2 Papp > 300 x 10-6 cm/s
    • Propranolol Papp 101 x 10-6 cm/s
  • Optimized ka and tlag
  • Converted from minimal PBPK model to full PBPK model

Budesonide_V22R1_UniversityOfManchester_20240502
Model Files Publication

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).
