An inhaler (1) comprising a housing (2) to receive a plurality of blisters (6a) each having a puncturable lid (6c) and containing a dose of medicament for inhalation by a user is disclosed. The inhaler comprises a mouthpiece (5) through which a dose of medicament is inhaled by a user, an indexing wheel (23) around which the blisters extend and an actuator (3) operable to rotate said indexing wheel to sequentially move each blister into alignment with a blister piercing member (9). The actuator is also operable to cause the blister piercing member to puncture the lid of an aligned 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 out of the blister and via the mouthpiece into the user's airway. The housing includes a chamber into which used blisters are fed by the indexing wheel. |
