Sujan,
Your specifications should not change, only your testing schedule. If your API has a specific SOP for all of its testing, that may need revision, depending on how it is worded. If you do not already have a written reduced testing procedure, you will need one.
Please note that if your specifications do change, you will need to resume full testing of the API to qualify it for reduced testing again.
Best of luck!

Dear Sir,
Thank you for your valuable input. If you please clarify "unless something is specifically written" .
After adopting reduced testing, we want mention below statement in the approved API specification "All test parameters will be done as intermittent testing (after every 10th batch), appearance and Identification by IR will be tested routinely."
Do we need to submitted revised API specification after that? If yes, how we should address?
Looking to hear from you.

Hello Sujan. None of the previous replies make reference that reduced testing is clearly described in the drug GMP regulations in 21 CFR 211, Subpart E, 122.80 - Control of Components and Drug Product Containers and Closures, specifically 211.84(d)(2) as follows:
"(2) Each component shall be tested for conformity with all appropriate written specifications for purity, strength, and quality. In lieu of such testing by the manufacturer, a report of analysis may be accepted from the supplier of a component, provided that at least one specific identity test is conducted on such component by the manufacturer, and provided that the manufacturer establishes the reliability of the supplier's analyses through appropriate validation of the supplier's test results at appropriate intervals."
Reduced testing likely has nothing to do with the NDA/ANDA filing, unless something is specifically written.

Hello Madam Arvilla,
Hope you are having good time.
Thank you for your valuable insight regarding this matter. I want to inform you that we have also system in place for vendor qualification with onsite inspection and review of the vendor's data. I forgot to include that in my earlier post. Sorry for that.
I want to know that what kind of filling mechanism should I follow to notify FDA regarding reduced testing of API ? Can you please comment on that.
Looking forward to hear from you soon.
With thanks,

Good day, Sujan.
You list seems comprehensive with one exception: you did not mention what has been done to qualify the vendor in terms of audits or amount of time / number of batches your company has with that vendor. It is my personal opinion that full testing every 10 - 20 batches may be too infrequent, depending on how quickly you go through those 10 - 20 batches. I would suggest that you perform full testing once every quarter, as things can change at a vendor site without your knowledge.
I hope this is helpful.

Dear Experts,
I would like to know about post approval ANDA filling category (PAS, CBE-30, CBE-0, AR) for reduction of API testing frequency.
Reduced testing strategy:-
- For every lot, some test parameters (Appearance, ID, Assay etc) will be performed by us and result of rest of the test parameter to be captured from Vendor CoA.
- Full tests to be performed at our end after every 10/20 lots
- Risk assessment has been performed to identify potential impact and action taken accordingly.
Your insight, experience or guidance reference is highly appreciated.
