Abstract

Use of bioactive agent in the manufacture of medicaments for pulmonary delivery of bioactive agent, where the medicament comprises perforated microstructures that are aerosolized by an inhalation device to provide aerosolized medicament in a form for administration to at least a portion of the nasal or pulmonary air passages. Independent claims are included for the following: (1) methods for forming perforated microstructures comprises: (a) providing a liquid feed stock containing the active agent; (b) atomizing the liquid feed stock to produce dispersed liquid droplets; (c) drying the liquid droplets under predetermined conditions to form perforated microstructures comprising the active agent; (2) a perforated microstructure; (3) methods for increasing the dispersibility of powders; (4) powders with increased dispersibility; (5) inhalation systems for pulmonary administration of bioactive agent to a patient; and (6) a method for pulmonary delivery of bioactive agents.
