Beyond IC50 and simple PK models – Considerations for discovery chemists

Conference: ACS
Division: Simulations Plus


What are the so-called “nonlinearities” in pharmacokinetics (PK) for multiple dosage of oral drugs? What are their causes and implications? While developing the Simulation Module [1] – an in silico tool for conducting PK simulations based on the Advanced Compartmental Absorption and Transit (ACAT™) model [2] – we have discovered a handful of interesting cases of nonlinear PK behavior.
