An inhaler for medicament comprises a housing (11) adapted to receive a pressurised dispensing container (12) of medicament. A mouth piece (14) for insertion into the mouth of a user of the inhaler is connected by duct means to an outlet (13) of the container. Air inlet means are provided for allowing air into the inhaler when a user applies suction to the mouth piece. The air inlet means (23) are provided at a location axially between the air outlet for the duct means and the mouth piece and passage means are provided connecting the inlet to a location adjacent the outlet of the duct means. The arrangement is such that, in use, when a user inhales through the mouth piece an airflow is created from the inlet to the mouth piece and the airflow has a component directed away from the mouth piece towards the outlet of duct means. <IMAGE> |
