Abstract:Pulmonary delivery systems should administer a high dose of the required formulation with the designated dry powder inhaler (DPI) to achieve therapeutic success. While the effects of device geometry and individual components used on powder dispersion are described in literature, potential effects of DPI surface properties on powder retention within the device and deagglomeration have not been adequately studied, but could impact inhalation therapy by modifying the available dose. For this, inner parts of a mod… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
