Disclosed is a particle engineered to deliver a bioactive agent to a patient's respiratory tract. The particles can be used in the form of a dry powder or in a stable dispersion comprising a non-aqueous continuous phase. In particularly preferred embodiments, the particles can be used with inhalation devices such as dry powder inhalers, fixed dose inhalers or nebulizers. The present invention is also the use of a bioactive agent in the manufacture of a medicament for pulmonary delivery, wherein the medicament is aerosolized using an inhalation device to provide an aerosolized medicament comprising the bioactive agent. A plurality of porous microstructures, wherein the aerosolized medicament is in a form of administration to at least a portion of the nasal or pulmonary respiratory tract of a patient in need of the aerosolized medicament.
