Abstract
Preparation of novel solvates of beclomethasone 17,21-dipropionate, by dissolution of beclomethasone 17,21-dipropionate in an ethereal or halogenated hydrocarbon solvent and precipitation by the addition of di-isopropyl ether. These new solvates are bulk stable, in both the micronized and non-micronized forms. The micronized form is especially suitable for the preparation of stable aerosol.
