ABSTRACT OF THE DISCLOSURE An apparatus for use in inhaling pharmaceutical aerosols. The apparatus includes a mouthpiece and a rigid housing for receiving an aerosolized medicine. The rigid housing has one or more orifices which are spaced from the mouth piece so that flow through the housing is possible but is limited by the orifice(s) to a desired volumetric flow rate. The patient is aided by having the initial velocity of the aerosolized medicine reduced to zero by virtue of the initial delivery of the same to the housing interior, and by having the volumetric flow rate of the inhaled medication maintained below required limits thereby providing the conditions for optimal dosing. Further, the ability of the patient to inhale to total lung capacity with the flow through chamber enhances penetration of aerosolized drug to the lung periphery, and improves the ease of use for the patient.
