The chief of US drug maker Baxter International said Tuesday its blood thinner heparin produced in China, which has been linked to dozens of deaths, appears to have been deliberately contaminated.
"We are greatly concerned that our heparin products appear to be
the target of a deliberate adulteration scheme," Baxter chief executive
Robert Parkinson said in prepared remarks to a US Congress panel.
"Patient safety is our number one priority, and we deeply regret the
impact this contamination in Baxter's heparin has had on patients," he
told a subpanel of the House of Representatives' Energy and Commerce
At least 82 deaths
At least 82 deaths from allergic reactions, have been reported to
the US Food and Drug Administration (FDA) since January 2007.
The FDA has identified the toxic substance as a synthetic compound
called oversulfated chondroitin sulphate (OSCS).
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.
FDA officials have said the contaminated batches came from factories
in China that make the drug for Baxter International, which recalled
its heparin in February after dozens of deaths in the United States
US health authorities said Chinese companies have also supplied
contaminated heparin to Australia, Canada, China, Denmark, France,
Germany, Italy, Japan, the Netherlands and New Zealand. – (Sapa-AFP)
