Abstract

A dry powder medicine inhaler has a housing (403) and a mouthpiece (405). An aerosolizing chamber (407) is formed between a front wall (408) and a rear wall (409) of the housing (403). An impeller (411) is rotatably mounted on a pin (413), to rotate within the aerosolizing chamber (407). Radial inlets (425) pass through the housing (403) and enter substantially tangentially into the aerosolizing chamber (407). A blister pack (421) on the housing (403) provides individual doses of powdered drug mixture into the aerosolizing chamber (407). The user inhales from the mouthpiece (405) causing the impeller (411) to spin and mix the powdered drug with air, which is inhaled by the patient.
