Process for conditioning of water-soluble substances

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