An 8/14-8/22/2025 FDA inspection at the Tentamus India Private Limited contract testing laboratory in Hyderabad, Telangana State, India, found significant violations of current good manufacturing practice (CGMP) regulations for finished drugs. A 3/3 Warning Letter says the specific violations were:

  • failure of the firm’s quality control unit to exercise its responsibility to ensure manufactured drug products comply with CGMP and meet established specifications for identity, strength, quality, and purity;
  • failure 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; and
  • failure to document required laboratory control mechanisms at the time of performance.

The letter notes that Tentamus limited access to some records requested during the inspection. It also says the firm’s quality systems are inadequate.

The company was told to correct any violations promptly and to respond with a list of specific steps it has taken to address the violations and prevent their recurrence, with a schedule for completing the corrections.
