Selected passages from the FDA letter

Quoted FDA text from the published dataset. These selected excerpts are not the complete letter.

Passage 1

Your firm failed to establish and follow adequate written procedures for cleaning and maintenance of equipment (21 CFR 211.67(b)).

Passage 2

Your firm failed to have, for each batch of drug product, appropriate laboratory determination of satisfactory conformance to final specifications for the drug product, including the identity and strength of each active ingredient, prior to release, and for each batch of drug product required to be free of objectionable microorganisms, appropriate laboratory testing, as necessary (21 CFR 211.165(a) and 211.165(b)).

Passage 3

Your firm failed to test samples of each component for identity and conformity with all appropriate written specifications for purity, strength, and quality. Your firm also failed to validate and establish the reliability of your component supplier’s test analyses at appropriate intervals (21 CFR 211.84(d)(1) and 211.84(d)(2)).

Passage 4

You failed to perform adequate identity testing on each shipment of each lot of incoming components (e.g., benzalkonium chloride, ethanol, glycerin) used in the manufacture of your OTC drug products. In addition, you relied on your suppliers’ certificate of analysis without establishing the reliability of each of your component suppliers’ test analyses at appropriate intervals.

Passage 5

You failed to adequately test each shipment of each lot of ethanol, used as an active pharmaceutical ingredient, for methanol. The use of ethanol contaminated with methanol has resulted in various lethal poisoning incidents in humans worldwide. See FDA’s guidance document Policy for Testing of Alcohol (Ethanol) and Isopropyl Alcohol for Methanol at: https://www.fda.gov/regulatory-information/search-fda-guidance-documents/policy-testing-alcohol-ethanol-and-isopropyl-alcohol-methanol.

Passage 6

You failed to adequately test each shipment of each lot of glycerin, used as an inactive ingredient, for DEG or EG contamination.

Passage 7

Failure to address violations may also cause FDA to withhold issuance of Export Certificates. FDA may withhold approval of new applications or supplements listing your firm as a drug product manufacturer until any violations are completely addressed and we confirm your compliance with CGMP. We may re-inspect to verify that you have completed corrective actions to address any violations.
