A system for the administration of a powdered medicament by inhalation comprises a container (21) containing a unit dose of medicament in powder form, and a device (10) having a chamber (16) adapted to receive the container (21). The device (10) has air inlets (19, 20) by which air may be drawn into the chamber (16) and a mouthpiece (14) by which air and entrained medicament may be drawn out of the chamber (16). The chamber (16) is substantially circular or annular in form and, in use, the container (21) follows an orbital path within the chamber (16), medicament being dispensed from the container (21) through at least one opening in the container (21). Also described are novel forms of packaging for powdered medicaments which are particularly suitable for use in the system.
