Abstract
An inhaler comprising a housing to receive a strip having a plurality of blisters is disclosed. Each blister has a puncturable lid and contains a dose of medicament for inhalation by a user. A mouthpiece is pivotally mounted to the housing through which a dose of medicament is inhaled by a user. The inhaler also has an actuating mechanism including a lever operable to sequentially move each blister into alignment with a blister piercing member depending from the mouthpiece. The actuating lever is also operable to cause the mouthpiece to pivot so that the blister piercing member punctures the lid of an aligned blister so that, when a user inhales through the mouthpiece, an airflow through the blister is generated to entrain the dose contained therein and carry it, via the mouthpiece, into the user's airway.
