title: Comparison of single pot and multiphase granulation. Part 2: Effect of the drying process on granules manufactured in a single pot granulator and dried either in situ or in a fluid bed dryer.
abstract: The aim of this study was to highlight the effect of the drying process on granules manufactured in a pilot scale single pot granulator and dried either in situ or in a fluid bed dryer, for formulations differing in drug substance and its concentration (1%; 25%). Although most of raw data were within specifications, single pot drying tended to improve granule comprimability and seemed less sensitive to formulation. Moreover, it was demonstrated that the formulation impacted on granule median diameter, packing ability, comprimability, residual lower punch pressure and tablet dissolution kinetics. Interactions between process and formulation were highlighted concerning tablet tensile strength and uniformity of mass.
