Abstract | Introduction: Many physicochemical, mechanical and environmental factors can influence charging of dry powder
inhaler (DPI) formulations - crystallinity is one of these factors. Due to differences in crystal packing and surface
energies, there may be differences in charge transfer behaviours between amorphous and crystalline materials.
Although the effect of crystallinity on electrostatic charging in DPI formulations has been investigated previously by
other researchers, the reported data were inconclusive since the samples not only differed in crystallinity, but also
in particle morphology and size distributions. Therefore, these variables are controlled in the present study to
determine the role of crystallinity in electrostatic charging of DPI formulations. The objective of this study was to
characterize inherent charges generated by amorphous and crystalline micron-sized salbutamol sulfate (SS) powders ..... |
