ABSTRACT:
A powder delivery device for the delivery into a patient's nasal cavity of a physiologically active agent in powdered form. A closure restricts the unwanted ingress of moisture into the device when the device is not in use. The action of opening or closing this closure may be linked to charging an air reservoir with air and/or moving a fresh powder-containing receptacle into communication with a powder delivery passage.
