I am a production pharmacist.
My question is:
For a certain validated tablet coating process in which the preparation procedure of coating solution and the quantities and specifications of chemicals used for preparation of coating solution are specified and validated , is it required that the volume of coating solution (after its preparation and before its application) is checked (to ensure that it falls within specified volume range) every time the coating solution is prepared during routine production of tablets batches?
Please if there is certain reference or guideline that mentions this issue please guide me to it.
Thanks a lot.
