Abstract The SeDeM Expert Diagram System is a galenic pre-formulation system, which evaluates the suitability of excipients and active pharmaceutical ingredients (API's) for direct compression into tablets as well as predicting possible formulations (i.e. ratios of API:excipient) to obtain acceptable direct compressible tablets. In this study, the prediction ability of the SeDeM Expert Diagram System with a special focus on testing the limits of the system was investigated. Three different...

Abstract The main objective of the present paper has been the development and study of two new biodegradable polyurethanes, PU(dithiodiethanol-DTDI) and PU[(iPr)Man-DTDI], to be used as sustained matrix forming excipients. Furthermore, their capacity to act as excipient for colon drug delivery systems has been evaluated. Thus, SeDeM diagrams have been obtained to investigate their suitability to be processed through a direct compression process. Matrices containing 10–30% w/w of the polymers...
