我们公司新建纯化水系统,在做PQ,微生物检查准备采用CP的方法。但同时想通过对比CP和USP纯化水微生物检查方法,得出CP的方法和USP方法等效,甚至是优于USP方法,
这样纯化水系统可以同时满足CP,EP,USP标准
不知道为啥传不了附件,只能将内容粘到帖子里
1. 概述 Introduction 1.1. 此VP方案是为了比较USP、EP、CP中纯化水微生物检验方法的等效性,根据验证结果,选取回收率较高的检验方法,作为技术有限公司GMP制剂实验室的纯化水系统(PWS)PQ和日常监控的微生物检测方法,从而确保该制剂实验室纯化水系统能满足GMP要求和CP, EP及USP相关标准。 The VP is used to compare the equivalence of purified water microbial test method among USP, EP, CP. According to the results of the validation, select the compendial test method with higher recovery rate as the microbial detection methods of the Performance Qualification and the daily monitoring for the purified water system (PWS) located in the GMP Drug Product Lab, and to ensure the purified water system of GMP Drug Product Lab can meet the standard of the GMP requirements as well as CP, EP, USP. 1.2. 验证小组由工程部、GMP制剂实验室、QA人员及合同实验室组成。 The validation team is made up of the engineering department, the GMP Drug Product Lab, the QA personnel and the contract laboratory. 2. 目的Objective 2.1. 通过对比USP、EP、CP中纯化水系统微生物检测方法的等效性以及回收率,确定纯化水微生物检验方法。确保GMP制剂实验室纯化水系统(PWS)的检测符合GMP要求和CP, EP及USP相关标准。 By comparing the equivalence and the recovery ratio of microbial test methods for purified water system among USP, EP, CP, select the purified water system microbiological test method and ensure that the microbial testing of the purified water system (PWS) in the GMP Drug Product Lab is in compliance with the requirements of GMP as well as the standards of CP, EP and USP.
1. 验证内容、方法及结论Qualification contents, method and conclusion 1.1. 描述 取三个不同批号的纯化水用薄膜过滤法检测微生物限度,通过比较试验菌在R2A和PCA培养基的恢复生长结果评价整个检验方法的准确性、有效性,通过计算回收率来判断检查方法是否有影响,通过验证来确认薄膜过滤法是适合于纯化水需氧菌总数的测定的最佳方法。三次试验中,稀释剂对照回收率应在50%~200%范围内,试验组回收率也应在50%~200%范围内。进行微生物限度检查方法(薄膜过滤法)验证时,所有的平皿和稀释剂都应该严格灭菌消毒、灭菌,确保对试验结果没有影响。 Description Membrane filtration method was used to detect the microbial limit in three different batches of purified water. Comparative test of recovery growth of bacteria in R2A and PCA medium was used to evaluate the accuracy and validity of the test method. The recovery rate was calculated to evaluate the effectiveness of the method and through validation to confirm that the membrane filtration method is suitable to test the total aerobic counts in purified water. In the three tests, the recovery rate of control diluent should be in the range of 50%~200%, and the recovery rate of the test group should also be in the range of 50%~200%. When the microbial limit test method (membrane filtration method) is verified, all the plates and the diluent should be strictly sterilized, to ensure that the test results are not affected.
