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.

Searching Tips

You can use a * character as a wildcard at the end of a alphanumeric search term. The search term must start with at least one character before the wildcard. E.g., Rifam* will get you “Rifampicin” and “Rifampin”.
You can also use a * character as a wildcard in the middle of a alphanumeric search term. The search term must still start with at least one character before the wildcard. E.g., Rif*in will also get you “Rifampicin” and “Rifampin” .
You can also use a * character as a wildcard at the start of a alphanumeric search term. However you must use forward slashes to delimit the search term and use a point before the wildcard. E.g., /.*picin/ will only get you “Rifampicin”.

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 vitrodata LogP: 5.8 -> 8.4 Caco-2 P_app > 300 x 10-6 cm/s Propranolol Papp 101 x 10-6 cm/s Optimized ka and t_lag Converted from minimal PBPK model to full PBPK model

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

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 (Altered Bioavailability and Pharmacokinetics in Crohn's Disease: Capturing Systems Parameters for PBPK to Assist with Predicting the Fate of Orally Administered Drugs - PubMed (nih.gov)).
