Abstract A medical administration device comprises a body (1) with a chamber (2) which is arranged to receive a blister pack (4) with a container (5) for medicament. The chamber is normally closed by a cover (7) which may be opened to permit a container to be inserted and located in the chamber. A mouthpiece (9) communicates with the chamber and a patient may inhale through it. The chamber has an air inlet (11). A spike (12) is engageable with a container in the chamber when the cover is closed to open a container located in the chamber so as to permit medicament to be withdrawn from the container when the patient inhales.
