[Revalidation of the in vitro specification limits after an in vitro-in vivo correlation].
A "Level A" in vitro/in vivo correlation was established for a sustained release theophylline (CAS 58-55-9) preparation (Bronchoretard) under investigation. Such a functional relationship is a valuable tool for predicting the in vivo performance of a product. Additionally, the in vitro specification limits could be justified or even enlarged based on such an extrapolation.
