  • Publication number: 20110253138
    Abstract: The disclosure relates to an inhaler comprising an outlet through which doses of medicament may be dispensed. The inhaler also comprises a dispensing mechanism having a primed state, in which it is ready for dispensing a dose, and a fired state, in which it has dispensed a dose. In one aspect, the inhaler also comprises a disabler which, after the final dose has been dispensed, is activated to disable the dispensing mechanism from generating a sound which has been audible when the dispensing mechanism has moved from its primed state to its fired state. In a second aspect, the disabler prevents the dispensing mechanism from being in its primed state when an outlet cover is in an open position, whereby a not ready indication is presented to the user.
