EU GMP ANNEX1的修订稿(2020年2月发布)里的确提到过这么一个类似的观点——
8.88 The integrity of the sterilized filter assembly should be verified by integrity testing before use, to check for damage and loss of integrity caused by the filter preparation prior to use. A sterilizing grade filter that is used to sterilize a fluid should be subject to a non-destructive integrity test post-use prior to removal of the filter from its housing. Test results should correlate to the microbial retention capability of the filter established during validation. Examples of tests that are used include bubble point, diffusive flow, water intrusion or pressure hold test. It is recognized that pre-use post sterilization integrity testing (PUPSIT) may not always be possible after sterilization due to process constraints (e.g. the filtration of very small volumes of solution). In these cases, an alternative approach may be taken providing that a thorough risk assessment has been performed and compliance is achieved by the implementation of appropriate controls to mitigate any risk of non-sterility.
参考中译为结合原康利华以及数个网络上流行的版本做的修订本——
使用前,应使用完整性测试验证已灭菌过滤器组装的完整性,以检查使用前的过滤器准备工作造成的破损及完整性降低。用于进行液体除菌过滤的除菌过滤器应在使用后进行非破坏性完整性检测,再将其从滤壳中取出。
测试结果应与验证时所建立的微生物截留能力关联起来。可用的测试方法包括起泡点法、扩散流法、水侵入法或保压/压力维持测试。通常认为,由于受工艺的限制(例如过滤非常少量/体积的溶液),PUPSIT(即已灭菌至使用前完整性测试) 并不能总是在灭菌后进行。在这样的情况下,可采用已经过完整风险评估并能通过实施可行控制手段来降低非无菌性的风险的那些替代性方法,从而实现合规性。
