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 or not the batch has already been distributed (21 CFR 211.192).
Passage 2Your 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) and 211.84(d)(2)).
Passage 3You failed to perform adequate identity testing on each shipment of each lot of incoming components (e.g., **(b)(4)**) used in the manufacture of your OTC topical drug products. In addition, you relied on your suppliers’ certificates of analysis (COA) without establishing the reliability of your component suppliers’ test analyses at appropriate intervals.
Passage 4You failed to adequately test your incoming component **(b)(4)** at risk of methanol contamination for identity before using it as an active pharmaceutical ingredient (API) in manufacturing your OTC topical drug products. The use of **(b)(4)** contaminated with methanol has resulted in various lethal poisoning incidents in humans worldwide. See FDA’s guidance document **(b)(4)** to help you meet the CGMP requirements when manufacturing drugs containing **(b)(4).
Passage 5Your 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 your firm’s quality control unit did not review and approve those procedures, including any changes (21 CFR 211.100(a)).
Passage 6You failed to ensure adequate validation for each of the manufacturing processes used to produce your OTC drug products. Additionally, your completed batch records did not include details pertaining to critical processing steps subject to variation (e.g., **(b)(4)** times, speeds) or identification of certain equipment including scales used for your weight-based manufacturing processes.
Passage 7Your firm failed to establish laboratory controls that include scientifically sound and appropriate specifications, standards, sampling plans, and test procedures designed to assure that components, drug product containers, closures, in-process materials, labeling, and drug products conform to appropriate standards of identity, strength, quality, and purity (21 CFR 211.160(b)).
Passage 8Your firm failed to establish an adequate quality control unit with the responsibility and authority to approve or reject all components, drug product containers, closures, in-process materials, packaging materials, labeling, and drug products and the authority to review production records to assure that no errors have occurred or, if errors have occurred, that they have been fully investigated (21 CFR 211.22(a)).
Passage 9Failure 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.
