An inhaler () is proposed (see FIG.), for the inhalation of a formulation () from capsules () that each contain one dose of the formulation. The capsules are preferably each emptied in a capsule chamber () 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.

Inhaler

The present invention relates to capsules for holding pharmaceutical preparations for powder inhalers with increased drug safety and capsules for pharmaceutical preparations for powder inhalers with improved adaptation to their use in powder inhalers. The capsules consist of water-insoluble hydrophobic synthetic materials which do not significantly affect the pharmaceutical quality of the contents themselves, but which improve the usability of the filled capsules with regard to their function, their longevity, and/or the geographic location of their use, and are advantageous at various stages from manufacture up to utilization.

Two-part capsule to accept pharmaceutical preparations for powder inhalers

A dispenser for pasty substances and/or liquids has two coaxially arranged metering pistons 11,24 which supply charges of material from two coaxially arranged pump chambers 14,23 through ejection channels 19,26 into an ejection chamber 20. The material can emerge from ejection chamber 20 through an outlet 4. This outlet 4 is controlled by means of plug 21 biassed in closing direction. When the metering pistons 11,24 are on their suction strokes material passes from the supply tanks 17,27 which are likewise arranged coaxially one inside the other. Such a configuration yields a dispenser which consists in essence of two separate dispensers, one inside the other. The two streams of material combine directly ahead of the outlet 4.
