ABSTRACT:
An inhaler comprising a compressed gas, such as Heliox gas is provided. The disclosed inhaler includes a first chamber containing a compressed gas which is in communication with an equalization chamber having pressure lower than the pressure of the gas in the first chamber. The inhaler also includes a drug storage chamber which is detachably coupled to the equalization chamber and operable such that a portion of the compressed gas from the equalization chamber fluidizes and aerosolizes the drug to produce a drug cloud. The drug cloud is directed into a spacer where it can be inhaled by a user.
