Selected passages from the FDA letter
Quoted FDA text from the published dataset. These selected excerpts are not the complete letter.
Passage 1Your firm failed to thoroughly investigate any unexplained discrepancy or failure of a batch or any of its components to meet any of its specifications, whether the batch has already been distributed (21 CFR 211.192).
Passage 2You failed to identify appropriate CAPA for these investigations to prevent recurrence of such events. There is no assurance that all batches produced under inadequate conditions have been thoroughly evaluated, and that your firm has identified all significant variables associated with your manufacturing process.
Passage 3Your firm failed to establish adequate written procedures for production and process control designed to assure that the drug products you manufacture have the identity, strength, quality, and purity they purport or are represented to possess, and to follow all of your written production and process control procedures (21 CFR 211.100(a) & 211.100(b)).
Passage 4You failed to adequately validate the drug manufacturing processes for your Over-the-Counter (OTC) drug products. For example:
Passage 5Your firm failed to perform, 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) & 211.165(b)).
Passage 6Your firm failed to conduct at least one test to verify the identity of each component of a drug product. 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) & 211.84(d)(2)).
Passage 7Failure 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 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.
