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”.

ValproicAcid_V21R1_NationalTaiwanUniversity_20231012

Model Files Publication

Three compound files for adults and 3 files for paediatrics are available for the parent compounds, Valproic Acid, reflecting the inputs required for EC tablets, tablets, and capsules, respectively. A compound file for the metabolite, 4-ene-Valproid Acid is available too. Details on the model assumptions and verification in V21R1 are available in the corresponding reference (DOI: 10.1002/psp4.13045) and supplement material on the journal (CPT: Pharmacometrics & Systems Pharmacology) website.

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

Tafenoquine

Model Files Publication

Brand Name(s) include: Arakoda, Krintafel

Disease: Malaria

Drug Class: Antimalarials

Date Updated: March 2022

The model at-a-glance

Absorption Model	First-Order
Volume of Distribution	Full PBPK (Method 3) Note: Kp scalar used
Route of Elimination	Undefined liver intrinsic clearance
Perpetrator DDI	CYP2C9 Inhibitor CYP3A4 Inhibitor
Validation	Four clinical studies describing single and multiple dose exposure of tafenoquine were used to verify the PBPK model, although some of these provided PK profiles and no PK parameters and vice versa. Of the clinical studies describing PK parameters, the model recovered 100% of the observed PK parameters within 1.5-fold (66% within 0.8-1.25-fold) and hence the model is considered predictive.
Limitations	Tafenoquine is administered with food to increase its exposure and minimize gastrointestinal side effects. The PBPK model was therefore developed to recover the PK of tafenoquine in the fed state. It should be noted that in the absence of information defining the fm of drug metabolizing enzymes, an undefined liver intrinsic clearance is used in the model and hence the model is not able to simulate the liability of tafenoquine as a victim of DDIs.
