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”.

Pyrimethamine

Model Files Publication

Brand Name(s) include: Daraprim

Disease: Malaria

Drug Class: Antimalarials

Date Updated: November 2021

Model at-a-glance

Absorption Model	First-Order
Volume of Distribution	Full PBPK (Method 2) Note: Kp scalar used
Route of Elimination	Non-specific hepatic metabolism (metabolizing enzymes not known)
Perpetrator DDI	OCT1 and OCT2 inhibitor
Validation	Three clinical studies were available for model verification. 100% of simulated Cmax and AUC were within 1.5-fold of observed and hence the model performance was deemed acceptable.
Limitations	The current model does not describe enzyme specific metabolism of pyrimethamine as there are no data for specific routes of metabolism. The current model does not mechanistically describe the absorption of pyrimethamine as the ADAM model over-predicts the extent of absorption. Although pyrimethamine is described as well absorbed in some literature, further analysis of the IV and PO data did not support this.
Updates in V19	Updated in vitrodata fup: 0.085 -> 0.095

Bosutinib_V18R2_Pfizer_20240809

Model Files Publication

The Bosutinib model uses a full PBPK distribution model (Method 2) and ADAM, where intestinal P-gp is accounted for (Km=0.38 uM, J_max = 15.45 pmol/min/cm², RAF = 4). The elimination is described via HLM clearance and assigned to CYP3A4, and a user defined renal clearance. An Immediate Release formulation is simulated with a user-defined solubility-pH profile. The performance of the file is described in Yamazaki et al., 2018 (Application of Physiologically Based Pharmacokinetic Modeling in Understanding Bosutinib Drug-Drug Interactions: Importance of Intestinal P-Glycoprotein - PubMed (nih.gov). In a follow-up paper using V18R2, the inputs for intestinal P-gp were updated (Km = 0.58 uM, J_max = 67.4 pmol/min/cm², REF = 1) based on Caco-2 data analysed in SIVA (Pan et al., 2021, Unraveling pleiotropic effects of rifampicin by using physiologically based pharmacokinetic modeling: Assessing the induction magnitude of P-glycoprotein-cytochrome P450 3A4 dual substrates - PubMed (nih.gov)).
