Abstract: A device for mechanically generating inhalable active substance particles from a consolidated medication supply and for conveying the active substance particles into the respiratory tract, wherein, in order to generate the active substance particles, there is a drivable face mill against which the front of a medication supply in the form of a ring-shaped body can be pressed, whereby the ring-shaped body forms the beginning of an inhalation tube ending in a mouthpiece and in that the housing surrounding the ring-shaped body and the face mill is provided with air inlet openings in the blade area of the face mill and said air inlet openings, together with the depressions located between the blades and the inhalation tube, form an air channel leading to the mouthpiece.
