Quoted FDA text from the published dataset. These selected excerpts are not the complete letter.
Passage 1Your firm failed to test samples of each component for identity and conformity with all appropriate written specifications for purity, strength, and quality (21 CFR 211.84(d)(1) and 211.84(d)(2)).
Passage 2You failed to perform adequate identity testing for each component lot used in the production of your over-the-counter (OTC) drug products, including **(b)(4)**, your active pharmaceutical ingredient (API). Additionally, you did not test **(b)(4)** content and **(b)(4)** for the presence of **(b)(4)**. You relied on the certificates of analysis (COAs) from your suppliers and failed to establish the reliability of each of your suppliers’ COA for component specifications and characteristics.
Passage 3You failed to adequately investigate multiple microbiological excursions in samples collected from your **(b)(4)** system in **(b)(4)**. You also failed to isolate and speciate microorganisms, and to determine the root cause for out-of-limit (OOL) test results. In response to these excursions, you proposed CAPAs. However, your CAPAs were inadequate to prevent recurrence.
