    摘要: A method for preparing stable crystals of a salt of Ceftizoxime which comprises mixing an aqueous solution of a salt of Ceftizoxime and isopropyl alcohol and collecting the precipitating crystals. Crystals obtained in this manner are more stable than the crystals obtained from prior art methods involving mixed solvents of water and ethanol.
