GMP第二百二十七条
(三)企业如需自制工作标准品或对照品,应当建立工作标准品或对照品的质量标准以及制备、鉴别、检验、批准和贮存的操作规程,每批工作标准品或对照品应当用法定标准品或对照品进行标化,
并确定有效期,还应当通过定期标化证明工作标准品或对照品的效价或含量在有效期内保持稳定。标化的过程和结果应当有相应的记录。
不就是工作标准品的标定吗?工作对照品一般是按照法定标准全检合格后,才能作为工作对照品。主要还是CTD文件中的3.2.s.5中对WS的要求:
1.80号文中(3.2.S.5)对照品一项中:
对于其他来源的外购对照品或者自制对照品,应提供相应的来源证明材料(或制备工艺、检验报告)、结构确证资料、质量标准、含量和纯度标定过程等。
2.CEP(PA/PE/CEP(04)1, 6R(201812)Content of the dossier for chemical purity and microbiological quality,也要求
Reference standards or materials (3.2.S.5)
When in-house standards/working standards, non-official or official standards other than the appropriate Ph. Eur. CRS are employed, they have to be suitably described (in terms of identification, purity, assay, etc.) and their establishment has to be demonstrated.
如果使用了不是欧洲药典对照品的自制的标准品/工作标准品、非官方或官方标准品,则必须进行适当描述(鉴别、纯度、含量等),其建标过程应是经过证明的
3.DMF 完整性评价中提到
For #44: Qualification data on inhouse primary RSs includes spectroscopic characterization and quantification by mass balance.
自制基准 RS 的确认数据应包括光谱特性和质量。
4.USP 、EP 中一般称之为 二级标准品。
5.ICH Q7 :
11.18 Where a primary reference standard is not available from an officially recognized source, an in-house primary standard should be established. Appropriate testing should be
performed to establish fully the identity and purity of the primary reference standard.Appropriate documentation of this testing should be maintained.
11.18 从官方认可的货源处无法得到基本参考标准品时,应该制备一个“内部基本标准品”。应当做合适的测试来全面制订该基本参考标准品的鉴别和纯度。该测试的相关证明文件应当保留。
11.19 Secondary reference standards should be appropriately prepared, identified, tested, approved, and stored. The suitability of each batch of secondary reference standard
should be determined prior to first use by comparing against a primary reference standard. Each batch of secondary reference standard should be periodically requalified in accordance with a written protocol.
11.19 二级参考标准品应当用合适的方法来制备,鉴别,测试,批准和储存。每一批二级参考标准品在第一次使用前,应当与基本参考标准品进行比较,来确定其适用性。每一批二级参考标准品应当根据书面方案,定期进行重新确认。
