A Process for providing water-soluble micronized substances, which can be produced, stored and used while maintaining the aerodynamic properties required for inhalation of such stubstances, which process is carried out byn a) reducing, if necessary, the residual water from the micronized substance by drying optionally at an elevated temperature and/or vacuum, b) conditioning said dried, micronized substances with a solvent, and c) eliminating residual solvent by storing in a dry place like vacuum or by purging with an inert gas. |
