Pharmaceutics Webinar | Development of Physiologically Based Pharmacokinetic and Biopharmaceutics Analysis and Modeling (PBPK and PBBM), 22 July 2025

Physiologically Based Pharmacokinetic (PBPK) modeling involves simulating the absorption, distribution, metabolism, and excretion (ADME) of drugs throughout the body. So, PBPK modeling is a mathematical tool which can describe the drug concentration in an organism using compartments that correspond to the different tissues and takes into consideration the physiology of this organism to parameterize the model.

Physiologically Based Biopharmaceutics Modeling (PBBM) is an established analysis mechanistically linking in vitro drug product performance (like dissolution) to in vivo absorption and bioavailability.

These types of models have become useful in drug development since their discovery, and are particularly important in early phases, when in vitro data and physicochemical properties can be used to obtain plasma profiles, which would be later validated in vivo, and until the clinical development phases, in which simulations can be used to describe drug performance in special populations.
