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”.

Quinine

Model Files Publication

Brand Name(s) include: Qualaquin

Disease: Malaria

Drug Class: Antimalarials

Date Updated: 2021

The model at-a-glance

Absorption Model	First-Order
Volume of Distribution	Minimal PBPK (Method 1)
Route of Elimination	CYP3A4 (fm = 0.50); renal clearance (fe = 0.1)
Perpetrator DDI	CYP2D6 Inhibitor
Validation	Three clinical studies describing Quinine PK were identified for model verification. Three clinical DDI studies where quinine was the victim of CYP-mediated DDIs were used to verify the PBPK model. All studies were well recovered with simulated Cmax and AUC GMRs within 1.5-fold of the observed
Limitations	The Simcyp quinine PBPK model was able to recover interactions CYP3A inducers and inhibitors with reasonable accuracy. Verification needed for perpetrator DDI assessment as literature data is unavailable at this time.
Updates in V19	Updated in vitrodata fup: 0.199 -> 0.37 Caco-2 A -> B Permeability: 70 x 10-6 cm/s -> 39 x 10-6 cm/s Propranolol reference Permeability: 101 x 10-6 cm/s -> 45 x 10-6 cm/s Minimal PBPK with Vss predicted through Method 1 Updated retrograde clearance

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
