FDA Identifies Contaminant Found in Recalled Heparin
WASHINGTON – U.S. health officials have identified a contaminant in batches of the blood thinner heparin associated with 19 deaths and are trying to determine how the chemical got into the drug.
The lots of heparin, whose key ingredient was imported from China, were recalled Feb. 28, and Food and Drug Administration officials say that no new deaths have been reported since that time.
(Heparin is widely prescribed to help prevent blood clotting in heart disease and for flushing infusion ports implanted under the skin, often used by Alphas for IV augmentation therapy.)
Dr. Janet Woodcock, head of the FDA’s Center for Drug Evaluation and Research, said the contaminant is oversulfated chondroitin sulfate, a chemical that does not occur naturally. Chondroitin sulfate is a natural compound that occurs widely and is used as a dietary supplement, but the oversulfated version has not been widely studied.
