GMP News - Analytical Quality Control

We recently reported on a case in which the failure to respond led to a Warning Letter. The U.S. Food and Drug Administration (FDA) has now published another incident that also goes in this direction. The FDA had planned an inspection at a manufacturing facility in Thailand, but all efforts to contact the firm were unsuccessful.

The EMA/CMDh nitrosamine Q&A document "Questions and answers for marketing authorisation holders/applicants on the CHMP Opinion for the Article 5(3) of Regulation (EC) No 726/2004 referral on nitrosamine impurities in human medicinal products" was updated again in January 2024 and is now available in revision 20. Like the three appendices, the Q&A document is published on the EMA website and can be viewed under "Questions and answers".

The updated text of the monograph "2.5.42. N-Nitrosamines in active substances and medicinal products" has been published on the website of the EDQM in the Pharmeuropa section and can be commented on until 31 March 2024, along with several other new drafts.

Following the draft chapter published in 2022, the new Ph. Eur. general chapter Comparability of alternative analytical procedures (5.27) has now been published in Supplement 11.5.

In January 2024, the U.S. FDA issued a Warning Letter to the company "Prime Lab LLC" after having inspected its site in July and August 2023. According to the WL, the firm failed to do proper incoming control tests for identity of their raw materials.

Even with increasing distance to the pandemic situation, manufacturers of disinfectant products still seem to be relying on less stringent controls. After a large number of Warning Letters regarding hand sanitizers with contaminated or poorly analyzed products in the Americas and Southeast Asia, a Turkish company is now affected. The company Sudesan in Istanbul received a Warning Letter from the FDA listing several deviations.
