Q7A 专家问答 第81页
4. Q. What does "appropriate testing of each chemical batch before blending" mean?"
问:“在混粉前对每批化学批号进行合适的测试”是什么意思?
Q7A states in Section 8.4 that out-of-spec batches should not be blended with other batches
for the purpose of meeting specifications. Appropriate testing is needed to ensure that no
blending of OOS material is occurring. This does not imply that you have to do the full set of
USP testing, for example, both before and after the blend, to look for things like heavy metals,
residue on ignition, things that historically have never been an issue. One would typically
include tests where variability is seen, for exam ple, impurity test, assay, moisture, etc.
答:Q7A 指南在第 8.4 部分说,超标批次不能和其他批次混粉来达到符合规格标准的目的。合适的测试是为了确保不发生超标批次参与混粉。不是要你去按照 USP进行全检,例如,在混粉
前后,测试那些重金属,灼烧残留,以及历史数据证明无关的项目。只需要对那些可能变化的项目进行测试,例如杂质测试,含量测试,水分等等。 |
