2008 Chinese heparin adulteration

Medicine contamination incidents 2008 Chinese heparin adulteration, refers to heparin adulteration incidents that occurred in the United States of America in 2008. Pharmaceutical company Baxter International subcontracted the creation of precursor chemicals of heparin to Scientific Protein Laboratories, an American company with production facilities located in China. Scientific Protein Laboratories then used counterfeit precursors to create the chemicals ordered. Baxter then sold this adulterated heparin in the US, which killed 81 people, and left 785 severely injured. This caught the attention of the media and the USA Food and Drug Administration leading to numerous ongoing lawsuits. Overview The raw material for the recalled heparin batches was processed in China from pig's intestines by the American pharmaceutical firm Scientific Protein Laboratories.Gardiner Harris Walt Bogdanich Walt Bogdanich Drug Tied to China Had Contaminant, F.D.A.

When the FDA conducted an inspection of Baxter's Chinese heparin supplier, it found serious deficiencies at the facility, which the FDA detailed in a warning letter.Warning Letter: Changzhou SPL Company, Ltd (a/k/a "Kaipu") https://www.fda.gov/ICECI/EnforcementActions/WarningLetters/2008/ucm1048332.htm https://web.archive.org/web/20090710042624/http://www.fda.gov/ICECI/EnforcementActions/WarningLetters/2008/ucm1048332.htm dead July 10, 2009 FDA Warning letter FDA 28 July 2010 Gardiner Harris Chinese Factory Linked to Drug Under Inquiry in U.S. https://www.nytimes.com/2008/02/14/business/worldbusiness/14heparin.html The New York Times February 14, 2008 2008-02-18 https://web.archive.org/web/20081209194821/http://www.nytimes.com/2008/02/14/business/worldbusiness/14heparin.html December 9, 2008 live The warning letter detailed that the company failed to monitor changes in the impurity profile of incoming heparin active raw material, to adequately investigate out-of-specification results, to document actual processing steps in batch records, to validate all critical steps in the process, to qualify all suppliers, and to use valid methods to test products. The FDA has stated that it does not have the funds nor bear the responsibility to inspect on a regular basis overseas upstream processors of finished active pharmaceutical ingredients such as heparin. However, according to the internationally harmonized guideline, ICH Q7, API manufacturers are fully responsible for qualifying their suppliers through on-site audits, testing, and regular communications.
