还有一个问题,叶老师,针对于起始物料的精制过程,我有看过Q11,其中有这么一段话,请问如何进行理解呢???选自http://zhuyujiao1972.blog.163.co ... 472720121173176528/,是否对于这种情况,是否是需要将该精致步骤作为工艺的一部分,起始物料应该从购回的粗品(或者说质量不合格的起始物料)开始,并且该步骤实质上也需要遵循Q7AGMP,但是这句话前提是针对的commercially available starting material,但是对于custom starting material呢??@hongwei2000 这个搞不懂呢??老师指教。

In some instances, additional purification steps by the drug substance manufacturer might be called for to ensure the consistent quality of a commercially available starting material. In these instances, the additional purification steps should be included as part of the description of the drug substance manufacturing process. Specifications should normally be provided for both incoming and purified starting material. 有时候,原料药制造企业需增加起始物料精制步骤,以确保市售起始物料的质量一致性。在此情况下,所增加的起始物料精制步骤应作为原料药制造工艺的一部分来描述。通常要提供购入的及精制过的起始物料的质量标准。
