In vitro deposition of the respirable fraction of dry powder inhalations determined by laser diffractometry and inertial impaction
Particle size analysis of drug and excipient is of particular interest for dry powder inhalation (DPI) formulations development and quality control. In this work, the deposition in the upper, the medium and the lower (i.e. the respirable fraction) Twin Impinger compartments of sodium cromoglycate (S...
