A powder inhaler for use in the treatment of medical problems of the air passages, lungs or bronchial conditions, such as bronchial asthma comprises an openable casing 3 having a mouthpiece and containing a replaceable magazine disc 1, 2 provided with a plurality of recesses or cups, each holding a dose of powder and being individually closed by a discrete closure element which can be opened and then reclosed. The disc may be indexed around to present a closed cap adjacent a projection 16 at the mouthpiece and then moved in the casing transverse to its rotational axis so that the projection removes the closure element. A ring (15, Fig 4) is provided in the top casing portion to assist reclosure of the closure element after inhalation. <IMAGE> |
