# FDA flags packaging certification as sole major deficiency for NRx preservative-free ketamine ANDA approval

-   FDA completed first-cycle review of NRX Pharmaceuticals’ preservative-free ketamine ANDA with no major drug, labeling, or CMC deficiencies. \* Outstanding item flagged as a Major Deficiency ties to container-closure performance evidence for a luer lock vial tip, not the ketamine formulation. \* FDA requested a manufacturer attestation on identical production lines and complaint-free history; agency committed to the shortest possible review cycle. \* Company cited 11.9 million units shipped across three FDA-approved ANDA products using the same vial system in the past 12 months.
