7. Failure to thoroughly investigate any unexplained discrepancy or the failure of any batch to meet any of its specifications, whether or not the batch has already been distributed, as required by 21 CFR § 211.192. Specifically, review of the HPLC assay chromatograms for release testing for Tannate Pediatric Suspension, lot #08046, revealed the presence of an unidentified peak at approximately [(b)(4)] RRT in the sample chromatogram. Your firm did not perform a timely investigation in regard to the unidentified peak. We acknowledge the tentative conclusion from your investigation, stated in your FDA-483 response, that the unknown peak represents the other active ingredient in the product, Phenylephrine Tannate. However, this determination should have been made at the time of the initial analysis. In addition, we not yet have received any documentation of the investigation, including the final conclusion and follow-up. |
