ABSTRACT:
An inhaler (2) includes a body (10) having a dispensing head (6) coupled thereto. Body (10) includes a storage chamber (24) for storing a supply of powdered drugs therein and a storage chamber (26) for holding a dessicating agent. A dispensing cylinder (60) contained in a transverse bore (40) in dispensing head (6) is laterally movable from a first transverse position in which a metering chamber (70) is in alignment with the feed hole (38) to a second transverse position in which chamber (70) communicates with the dispensing passageway (48) of nozzle (30). In the first transverse position, metering chamber (70) may be filled and in the second transverse position the drugs contained in chamber (70) may be inhaled through nozzle (30). In addition, a cylindrical insert (76) received around dispensing cylinder (60) seals storage chamber (24) when inhaler (2) is not in use.
