The purpose of this study was to develop inhalable particles that can reach deep into the lungs efficiently independent of inhalation patterns of patients and inhalation devices. We prepared porous particles including L-leucine (Leu), a dispersive agent, by a spray-freeze-drying (SFD) method and examined the influence of inspiratory flow patterns and(More)
While dry powder inhalations are commonly used to treat pulmonary diseases, their clinical performance depends on patient inspiratory flow patterns. The purpose of this study was to develop a new powder with high and stable therapeutic performance for various patients. We applied the supercritical antisolvent (SCF) method to salbutamol sulfate (SS) to(More)
