Abstract: A solidified drug supply for generating inhalable drug particles with the aid of a metering device includes a removal unit, with the drug supply being brittle and textureless. The density and the mechanical strength of the drug supply is abraded everywhere in such a way that the structure of the material removed from one side of the drug supply by the metering device is uniform across the entire usage region in the direction of the removal.
