sir pleae tell me which criterias should defined to consider cleaning validation cycles.
presently i am working in pharma industry we are considering three cycles to complete cleaning validation. for example we are using maximum dose as criteria . so likewise e what are other criterias?

This question is too broad to give a specific answer, please be more detailed with your question.

Dear friend,
as per my view you need to consider products which are highly toxic, more potent and difficult to clean. it does not depend not only the active but also on the inactive which we are using if they are difficult to clean which if jot cleaned will have potential impact on the quality of the product.
