PRE-FREEZE DRIED PREPARATION OF AZACITIDINE, FREEZE DRIED PREPARATION OF AZACITIDINE AND METHOD OF MANUFACTURING FOR THE SAME

摘要

The present invention provides a pre-freeze dried azacitidine preparation, a freeze dried azacitidine preparation, and a method of manufacturing the freeze dried azacitidine preparation. The pre-freeze dried azacitidine preparation of the present invention has improved stability in an aqueous solution. When the pre-freeze dried azacitidine preparation is frozen and dried under predetermined process conditions including a freeze drying cycle, a stability-improved freeze dried azacitidine preparation can be usefully produced.
