Case Study
RevK – Reverse dosimetry and PBPK prediction


In this case study the Open Systems Pharmacology physiologically based pharmacokinetic (PBPK) model will be made accessible and used for risk assessment-relevant scenarios.


  • Reverse dosimetry (finding the exposure dose of a chemical leading to a prescribed blood plasma concentration);
  • Forward predictions of plasma and tissue concentrations following a prescribed exposure dose or concentration. In this case, Monte Carlo simulations of inter-individual variability will also be performed.

Risk assessment framework

This case study is particularly associated with Tier 2, step 7B (biokinetic refinements). PBPK models tend to be information hungry and are typically reserved to higher tier problems. However, there is a current push toward their use in lower prioritization tiers. This typically requires integration of databases and in silico models to inform PBPK parameter values.
