Linghai ZhanWang Records Show CGMP Violations
An FDA review of records submitted by Linghai ZhanWang Biotechnology Co. in Jinzhou, Liaoning, China, in response to an agency 2/26/2024 request, found significant violations of current good manufacturing practice (CGMP) regulations for finished drugs in the firm’s manufacturing of over-the-counter drugs. A 2/25 Warning Letter says the specific violations were:
- failure to test samples of each component for identity and conformity with all appropriate written specifications for purity, strength, and quality;
- failure to establish an adequate written testing program designed to assess the stability characteristics of drug products and to use results of stability testing to determine appropriate storage conditions and expiration dates; and
- failure to establish an adequate quality control unit with the responsibility and authority to approve or reject all components, drug product containers, in-process materials, packaging materials, labeling, and drug products.
FDA says it placed all drugs and drug products produced by the company for import into the U.S. on a 2/10 Import Alert. Linghai was told to correct the violations promptly and to respond with a list of specific actions it has taken to address the violations and prevent their recurrence, with a schedule for completing the corrections.
