FDA清洁工艺验证指南
Routine Production In-Process Control Monitoring - Indirect testing, such as conductivity testing, may be of some value for routine monitoring once a cleaning process has been validated. This would be particularly true for the bulk drug substance manufacturer where reactors and centrifuges and piping between such large equipment can be sampled only using rinse solution samples. Any indirect test method must have been shown to correlate with the condition of the equipment. During validation, the firm should document that testing the uncleaned equipment gives a not acceptable result for the indirect test.
日常生产的中间控制监测:一旦某清洁方法得到验证之后,日常监测可使用间接检测法,如电导率检测。对于原料药生产商来说,使用的反应罐和离心机,大型设备之间的管道连接,只能对其漂洗液取样。这种情况下,必须说明间接检测法与设备状况的相关性。验证过程中,也应有书面证明:用间接法检测未清洗设备时,检验结果能够证明该设备不能使用以及未清洗。即该检测结果能够得出不能够接受当前设备状况的结论
我认为可以采用上述“间接检测法”来进行持续的确认,也就是所谓的清洁检查,或者叫清洁效果确认。 |
