RDD 2012: Investigation of the Microstructure of Combination Dry Powder Inhaler Formulations by Atomic Force Microscopy and Raman Chemical Imaging
May 20, 2012 The microstructure of combination DPI formulations is complex and is related to the surface interfacial interactions between components of the formulation, which define the structure and thereby performance of the formulation (1, 2, 3). Previous studies have attempted to investigate the microstructure of combination DPI formulations using…
