Report of the workshop on : in vitro and in vivo testing and correlation for oral controlled/modified release dosage forms

This report is from the second workshop held in Washington DC on controlled/modified release dosage forms. The objectives were to determine the optimum information needed to characterize the drug entity and the drug dosage form, to explore the in vitro-in vivo relationship so as to determine the criteria for establishing an in vitro-in vivo correlation as well as the usefulness of in vitro data in the drug approval/regulatory process.
