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”.

The model at-a-glance

Absorption Model	First-Order
Volume of Distribution	Full PBPK (Method 2)
Route of Elimination	CYP3A4 (fm =100); renal clearance (fe = 0.05)
Perpetrator DDI	CYP2C9 Inhibitor CYP2D6 Inhibitor CYP3A4 Inhibitor
Validation	Six clinical studies describing single and multiple dose exposure of mefloquine were used the verify the PBPK model. Most of the studies (83%) were within 1.5-fold, with all simulations falling within 2-fold of the observed values. Two clinical DDI studies where mefloquine was the victim of a CYP3A4-mediated DDI were accurately recovered using the PBPK model.
Limitations	Only profiles of plasma concentrations assessed, many studies report blood concentrations Mefloquine has significant uptake into erythrocytes and haematocrit levels typically not reported Could be important in disease population (Possible time-varying B/P for Malaria patients?) Cmax for doses > 750 mg over predicted fa possibly decreases with dose, more data needed to fully determine the cause Most literature data extracted from graphs of mean data, difficulty determining accurate early time points due to poor image quality Verification needed for perpetrator DDI assessment as literature data is unavailable at this time
Updates in V19	Updated in vitrodata fu_p: 0.016 -> 0.015 B:P ratio 1.7 -> 1.1 and subsequent re-calculation of CLint using the retrograde approach Converted model to full PBPK distribution model with Vss predicted through Method 2 Sensitivity analysis of ka

Esomeprazole_V14R1_USFDA_20160711

Model Files Publication

Note: This compound file is for esomeprazole solution, not for delayed release esomeprazole formulations 2. V12R1 compound file built to simulate adult PK. Supplied file is a V14R1 file that has been tested to generate identical results under the condition of mutual interaction with R-omeprazole (Condition 2 in Table II in our publication).
