Good evening all!
I have one question, could you please help me:
Can I use different manufacturer API in prospective validation of FDF (ointment) production? Or all three batches will be produced from one API?
May be you could suggest guidelines point where its is defined?
All validation batches should have same source of API. If source of API will change re-validation has to be executed.(REF: WHO Technical Report Series, No. 937, 2006, section 7.1
Thank you for your answer.
Could you please notify WHO ref. intranet address. I found this: http://whqlibdoc.who.int/trs/who_trs_937_eng.pdf
. Are you think section 7.1 - Annex 7- validation ?
