WHO Looking for Alternate Levonorgestrel API Sources
The World Health Organization (WHO) says it is working with finished pharmaceutical product manufacturers to identify additional sources for levonorgestrel following an FDA 3/8 import alert on Qinhuangdao Zizhu Pharmaceutical in Hebei, China. In its response to the import alert, WHO says that FDA investigators found failures in the level of adherence to cGMP for active pharmaceutical ingredients, particularly a breach of data integrity related to testing in the quality control laboratory.
The response says the WHO has been in touch with the company and with FDA to discuss the matter. “At the moment, there is no alternative levonorgestrel API which has been prequalified by the WHO prequalification team,” it says.
Manufacturers of prequalified products that use levonorgestrel manufactured by Qinhuangdao Zizhu were asked by WHO to take additional measures such as comprehensive testing upon receipt to help ensure that the quality of all batches of levonorgestrel is assured.
