Abstract The methods used for flow characterization of a powder mass include the angle of repose (AOR), Carr index (CI), and powder flow tester (PFT). The use of nanosilica as a flow modifier (glidant) is very common in industry. This study aims to compare the glidant effect of hydrophobic and hydrophilic silica on a poorly flowable active pharmaceutical ingredient (ibuprofen) by different flow characterization techniques. Different percentages (0.5, 1.0, and 2.0 wt%) of both types of mixed...

Abstract Orodispersible films possess a great potential as a versatile platform for nanoparticle-loaded oral dosage forms. In this case, poorly water-soluble organic materials were ground in a stirred media mill and embedded into a polymer matrix. The aim of this study was the shortening of this manufacturing process by the integration of several process steps into a stirred media mill without facing disadvantages regarding the film quality. Furthermore, this process integration is time...
