The present invention relates to an inhalation device for dispensing a medicament from a valved dispenser. The device includes a housing having a longitudinal slot, an associated nozzle body, a cylindrical advance tube that slidably receives therein the dispenser and that has an external helically extend thread member, an advance ring that associates with the dispenser and that slidable engages the advance tube, and a level indicator. A zigzag track in either the advance tube or the advance ring, and a mating stud in the other of the ring or tube causes the advance tube to rotate when the ring is moved reciprocally when the dispenser is actuated. The level indicator device linearly indicates a remaining amount of medicament.
