1、在决定每个清洗程序验证分级的前的风险评估中涉及到以下几点如何理解??
manufacturing campaigns,processing time scales, idle time and idle conditions, number of products covered by the respective cleaning procedure;
2、针对于The cleaning validation risk assessment will also identify any APIs that are considered to be a beta-lactam penicillin, steroid, and cephalosporin, oncological, Ames positive, mutagenic or allergenic in nature,这句话,在国外对于这些高活性,高毒性产品还允许非专用设备????
3、In the matrix approach, either 3 elements of the same group are tested once or the worst case of the group is tested 3 times.对于这句话的理解,是不是针对这个对于使用最坏情况分组,那么对于清洗方法的验证,对于分为一组最难清洗组(A,B,C),对于清洁方法的验证可以分别对A,B,C各进行一次验证,也可对其中一个(比如A)进行三次清洁验证????按照后面的In the matrix worst case approach, only one cleaning run for each of three different APIs / intermediates of the same category (or combination thereof) or three runs utilising the worst case product of the same category is acceptable.,应该是那个意思。
4、The same may be applied for equipment, i.e. groups of similar or equivalent equipments can be treated as a matrix and grouped according to risk assessment (same material, size, complexity, configuration etc.)这句话应该怎么理解呢???到底清洁验证中的分组(bracket),是根据药品还是根据设备呢??或者两者兼具??搞不懂
5、Micro biological Contamination:
Micro biological contamination is possible if the last cleaning step is performed with water or mixtures of organic solvents with water. For equipment which is cleaned by refluxing organic solvents the risk of relevant contamination is minimal.
对于final rinse是使用甲醇的设备,是否没有必要再进行微生物限度的检查????@hongwei2000 @windy
6、cleaning validation master plan谁有??可否借鉴一下???
7、评判是否执行rinse淋洗还是swab擦拭的依据是closed equipment,其中对于closed equipment是如何界定的呢???其实个人认为对于密闭设备或者非密闭设备都必须进行淋洗取样,如果设备擦拭取样能够accessable,那么必须进行擦拭取样以确认淋洗取样的测试结果。
5、visual check没有通过,就执行偏差管理,那么对于使用人工(机械)清洁,是否就不存在这个问题???这个程序是否是针对于完全的CIP清洁程序制定的??
6、requirements for whole equip.chain met是指什么意思呢???为什么在判定为NO的情况下重新返回执行plan cleaning步骤,应该指向produce deviation report呢,然后再回到plan cleaning步骤吧;同样为什么validation runs complete判定为NO的情况下,也返回重新执行plan cleaning,应该返回至perform cleaning according to SOP步骤吧????
7、level of validation是指什么???similar APIs/intermediates中similar如何界定??worst case situation进一步理解;
