Physiologically based pharmacokinetic (PBPK) modeling for biopharmaceutics applications holds great promise as modelling and simulation tool in the field of modern oral modified release (MR) products. Understanding of gastro-intestinal absorption related processes is crucial to ensure the successful development of complex oral drug generic products. In the recent years, PBPK approach has been gradually influencing decision making ability of pharmaceutical industry as well as regulatory agencies. However, there is a gap in understanding its contribution in the field of oral modified release products. In this review, we have collected different recent research articles illustrating the significant contribution of PBPK to the research and development process of oral MR products, with special emphasis on generic drug products. Concretely, literature examples on the utility of PBPK formulation development, for in vitro- in vivo correlations (IVIVC) and prediction of oral bioavailability, and for in-silico food effect predictions were included in the review.
