摘要 |
A crystalline mono hydrochloride salt of (4S,4aS,5aR,12aS)-4-dimethylamino-3,10,12,12a-tetrahydroxy-7-[(methoxy(methyl)amino)-methyl]-1,11-dioxo-1,4,4a,5,5a,6,11,12a-octahydro-naphthacene-2-carboxylic acid amide is disclosed having improved stability. In addition, a crystalline mono mesylate salt and crystalline mono sulfate salt of (4S,4aS,5aR,12aS)-4-dimethylamino-3,10,12,12a-tetrahydroxy-7-[(methoxy(methyl)amino)-methyl]-1,11-dioxo-1,4,4a,5,5a,6,11,12a-octahydro-naphthacene-2-carboxylic acid amide are also disclosed having improved stability. A pharmaceutical composition containing the crystalline salts and methods of treating inflammatory skin disorders and bacterial infections comprising administering the crystalline salts are also disclosed.
