Abstract

An inhaler (1) is proposed (see FIG. 1), for the inhalation of a formulation (2) from capsules (3) that each contain one dose of the formulation. The capsules are preferably each emptied in a capsule chamber (4) by being set in motion by a stream of air flowing through the capsule chamber. The stream of air can be generated by the inhalation of a user or patient and/or can be generated actively generated by the inhaler. For simple handling, the inhaler has a means for, in particular, automatic filling, emptying and/or cleaning of the capsule chamber, if the latter is used more than once. Alternatively, the inhaler has a large number of capsule chambers that each preferably already contain a capsule and re preferably used just once.
