Mechanistic Oral Absorption Modeling and Simulation for Formulation Development and Bioequivalence Evaluation: Report of an FDA Public Workshop

摘要

On May 19, 2016, the US Food and Drug Administration (FDA) hosted a public workshop, entitled a??Mechanistic Oral Absorption Modeling and Simulation for Formulation Development and Bioequivalence Evaluation.a?? 1 The topic of mechanistic oral absorption modeling, which is one of the major applications of physiologically based pharmacokinetic (PBPK) modeling and simulation, focuses on predicting oral absorption by mechanistically integrating gastrointestinal transit, dissolution, and permeation processes, incorporating systems, active pharmaceutical ingredient (API), and the drug product information, into a systemic mathematical wholea??body framework.
