Abstract

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.
