abstract |
The present invention relates to novel solvates of beclomethasone dipropionate with alkanes, especially n-alkanes, having frorn 5 to 8 carbon atoms, and to their preparation, e.g. by contacting beclomethasone d propionate with the alkane. The novel solvates can be used in inhalation devices and in the preparation of beclomethasone dipropionate-trichlprofluoromethane solvate. |
