以USP 的非无菌头孢唑林钠原料药为例
Cefazolin Sodium
C14H13N8NaO4S3 476.49
5-Thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylic acid, 3-[[(5-methyl-1,3,4-thiadiazol-2-yl)thio]methyl]-8-oxo-7-[[(1H-tetrazol-1-yl)acetyl]amino]-, monosodium salt (6R-trans).
Monosodium (6R,7R)-3-[[(5-methyl-1,3,4-thiadiazol-2-yl)thio]methyl]-8-oxo-7-[2-(1H-tetrazol-1-yl)acetamido]-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylate [27164-46-1].
» Cefazolin Sodium has a potency equivalent to not less than 89.1 percent and not more than 110.1 percent of cefazolin sodium (C14H13NaN8O4S3), calculated on the anhydrous basis.
Packaging and storage— Preserve in tight containers.
. . . . . .
Other requirements— Where the label states that Cefazolin Sodium is sterile, it meets the requirements for Sterility and Bacterial endotoxins under Cefazolin for Injection. Where the label states that Cefazolin Sodium must be subjected to further processing during the preparation of injectable dosage forms, it meets the requirements for Bacterial endotoxins under Cefazolin for Injection.
因为在制作无菌制剂的过程中,(例如冻干制剂,水针)一般没有去除内毒素的工艺单元,所以要求原料里的内毒素要低。非无菌原料药生产不需要用注射用水,纯化水即可。
