1. An apparatus for aerosolizing a powdered medicament, the apparatus comprising:

  • a pressurization cylinder, a piston slidable within the cylinder to pressurize a gas within the cylinder;

    a handle coupled to the cylinder, the handle being movable between an extended position and a home position to pressurize the gas within the cylinder;

    an aerosolizing mechanism adapted to aerosolize a powdered medicament that is held within a receptacle with pressurized gas from the cylinder;

    a carriage assembly adapted to receive the receptacle and to couple the receptacle to the aerosolizing mechanism; and

    a first and a second interlock which are operably engageable with the carriage assembly to prevent coupling of the receptacle with the aerosolizing mechanism, wherein the first interlock is released to allow movement of the carriage upon movement of the handle to the extended position, and wherein the second interlock is engaged when the receptacle is partially inserted into the carriage assembly.
