Abstract
A system and method for administering a drug, at a selected dose, via the respiratory tract. Spray-dried liposome particles containing the selected dose of the entrapped drug are released into the air in aerosolized form, either by entrainment in an air or propellant stream, or by release from a pressurized can containing a suspension of the liposomes in a fluorchlorocarbon solvent.
