Share

An FDA review of records submitted by Ningbo Poplar Daily-Use, a manufacturer of over-the-counter drugs in Yinzhou, Ningbo, China, in response to an agency request, found significant violations of current good manufacturing practice (CGMP) regulations for finished drugs. A 2/5 Warning Letter says specific violations were:

  • failing to have for each batch of drug product appropriate laboratory determination of satisfactory conformance to final specifications for the drug product, including the identity and strength of each active ingredient, before release;
  • failing to conduct at least one test to verify the identity of each component of a drug product; and
  • failing to establish and follow an adequate written testing program designed to assess the stability characteristics of drug products and to use the results of stability testing to determine appropriate storage conditions and expiration dates.

The letter says FDA recommends the firm retain a qualified consultant to perform a comprehensive audit of its operation for CGMP compliance and to assist Ningbo in meeting CGMP requirements if it intends to resume manufacturing drugs for the U.S. market.

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