Abstract

An inhaler (1) is disclosed. It comprises a housing (2) to receive a strip (6) of blisters (6a) each having a puncturable lid (6c) and containing a dose of medicament for inhalation by a user, a mouthpiece through which a dose of medicament is inhaled by a user and, an actuator (3) operable to sequentially move each blister into alignment with a blister piercing member (7, 9). The actuator is also operable to cause the blister piercing element to puncture the lid of a blister such that, when a user inhales through the mouthpiece, an airflow through the blister is generated to entrain the dose contained therein and carry it but of the blister and via the mouthpiece into the user's airway.
