Tenacious sputum poses a critical diffusion barrier for aerosol antibiotics used to treat cystic fibrosis (CF) lung infection. We conducted a proof-of-concept study using dense poly(ethylene glycol) coated polystyrene nanoparticles (PS-PEG NPs) as model muco-inert particles (MIP) formulated as a powder using an excipient enhanced growth (EEG) strategy, aiming to minimize extrathoracic airway loss, maximize deposition in the airway and further overcome the sputum barrier in the CF lungs. The EEG aerosol formulation containing PS-PEG MIP was prepared by spray drying and produced discrete spherical particles with geometric diameter of approximately 2 μm; and >80% of the powder dose was delivered from a new small-animal dry powder inhaler (DPI). The MIP released from the EEG aerosol had human airway mucus and CF sputum diffusion properties comparable to the suspension formulation. These properties make this formulation a promising pulmonary drug delivery system for CF lung infections. Dry powder aerosol containing muco-inert particles (MIP) as a promising pulmonary drug delivery platform. Micrometer-sized excipient enhanced growth (EEG) aerosol particles achieve good emptying efficiency from dry powder inhalers and minimize mouth-throat losses. The high humidity in the airway increases aerosol particle size and enhance airway deposition. MIP released from the EEG aerosol particles rapidly diffuse into the sputum to release drug.
