A PAT-based qualification of pharmaceutical excipients produced by batch or continuous processing
Contributor(s):: Hertrampf A., Müller H., Menezes J.C., Herdling T.
Pharmaceutical excipients have an influence on the main requirements for medicinal products (viz., quality, safety and efficacy) but also on their manufacturability. During product lifecycle it may become necessary to introduce minor changes (e.g., to continuously improve it) or major changes in...

100% visual inspection of tablets produced with continuous direct compression and coating
Contributor(s):: Barimani, Shirin, Sibanc, Rok, Tomazevic, Dejan, Meier, Robin, Kleinebudde, Peter
Visual appearance of tablets is an important property for patients. Since the visual appearance is most strongly influenced by the applied coating, this necessitates a high level of process control and homogeneity in the coating process. In recent years, a number of tablet coaters have been...
