The invention relates to a compressed air inhaler for the pulmonary application of a liposomal powder aerosol that carries active agents or is uncharged. n The aim of the invention, providing an inhaler with which the pulmonary application of, in particular, liposomes carrying active agent is enabled without forced breathing manoeuvres and with which the active agent can be transferred to the desired place of action in a sufficient amount without the active agent escaping, is solved by the compressed air inhaler for the pulmonary application of a liposomal powder aerosol entailing a receptacle 20 for a watery liposome dispersion, in which the liposomes carrying the active agent are dispersed in water, which is connected via a liquid dosing device 19 with an atomiser nozzle 1 and with a drying unit 17 such as an atomising chamber for the spray drying of the liposomes, to which said drying unit an exit 18 such as a mouthpiece is connected, in which the atomiser nozzle 1 has separate supply channels 14,16 for the compressed air and the liposome dispersion-FIG. 1 -. The aim of the invention is further a new kind of powder aerosol comprising liposomes or nano-particles. |
