- a housing;
an aerosol generator contained within the housing;
a medicament feed system to supply medicament to the aerosol generator; and
a mouthpiece comprising;
a medicament flow passage to provide aerosolized medicament from the aerosol generator to an outlet of the medicament flow passage; and
an air flow passage separate from the medicament flow passage, the air flow passage having an inlet in fluid communication with an ambient atmosphere and an outlet, wherein the outlets of the medicament flow passage and air flow passage are provided at an end of the mouthpiece to provide simultaneous flows of medicament and air that mix in the user'"'"'s mouth upon inhalation by the user at the end of the mouthpiece.
