Abstract

An inhaler such as a breath-actuated inhaler for delivering medicament by inhalation, comprising a housing for receiving a canister of medicament actuatable to deliver a dose of medicament, a detector for detecting actuation of a received canister, a timer responsive to the detector to measure the elapsed time from actuation of the canister, and an indicator means responsive to the timer to indicate when a predetermined time has elapsed during which the user should maintain inhalation or delay exhalation. This allows the inhaler to provide an indication of how the user should breath to properly receive a dose of medicament. The indicator means may be further responsive to the timer to indicate when a second predetermined time has elapsed.
