ABSTRACT:
Apparatus for use in inhaling pharmaceutical aerosols. The apparatus comprises a mouthpiece for supplying a pharmaceutical composition to the mouth of a patient, a rigid chamber for holding the aerosol prior to inhalation, the rigid chamber having orifices to limit the flow of air therethrough, and a collapsable chamber from which the patient inhales unmedicated air prior to inhaling the medicated air from the rigid chamber. The apparatus increases medication delivered to the small peripheral bronchi, while it limits deposition in the oropharynx. The patient is aided in inhaling a volume of unmedicated air, after which he automatically begins to receive the aerosolized medication with the inhaled air. The volumetric flow rate of the inhaled medication is kept below required limits for optimal dosing.
