WASHINGTON (AFP) - Four years after US drug-maker Baxter International's blood thinner heparin was contaminated in China, causing dozens of deaths, US regulators on Friday issued draft guidelines for safe production.
Heparin, a blood thinner used by millions of patients during kidney dialysis and heart surgery to prevent blood clots, is normally produced from pig intestines.
After reports of allergic reactions to heparin began appearing in November 2007, the US Food and Drug Administration found that a substitute synthetic compound called oversulfated chondroitin sulfate (OSCS) had caused the toxic reactions.
Chinese officials rejected the FDA's conclusions, saying the chemical had nothing to do with the allergies and deaths, but the FDA began testing heparin imports for OSCS in 2008 to assure safety of the drug stocks.
