METHOD FOR CONDITIONING WATER-SOLUBLE SUBSTANCE

摘要

PROBLEM TO BE SOLVED: To provide a water-soluble micronized substance which can be produced, stored and used while maintaining the aerodynamic properties required for inhalation of such substance and has physicochemical property improved in dried state and facilitate technical treatment of the substance thereby and significantly increases medical value. SOLUTION: The water-soluble micronized substance has a stable crystalline form and is selected from a group consisting of a carbohydrate, an amino acid and a medicine and has <10μm particle diameter and releases of maximum heat of 0.1 J/g when the substance is treated with steam after the substance is conditioned with a solvent.
