A single-dose cartridge inhaler comprises a dosing chamber configured to contain dry powder medicament, a transducer and a controller electrically coupled to the transducer. The medicament delivery device is capable of delivering a therapeutically effective dose of dry powder medicament in response to between 2-20 tidal inhalations, the dose preferably having a mass median aerodynamic diameter (MMAD) of about 6 microns or less and a fine particle fraction of at least 30%.
