WASHINGTON — The Food and Drug Administration is lifting severe safety restrictions on the former blockbuster diabetes pill Avandia, citing recent data suggesting that the much-debated medication does not increase the risk of heart attack.
The repeal means patients will no longer have to enroll in a special registry to be eligible to receive the drug. Additionally, the drug will be available at most pharmacies, whereas it was previously limited to certain registered pharmacies. Those safety restrictions and others were put into place in 2010, severely curbing U.S. prescriptions for the GlaxoSmithKline drug.
Monday's ruling is a belated victory for the British drugmaker, which has spent more than a half-decade defending the safety of Avandia, once the best-selling diabetes drug in the world. Sales began plummeting in 2007 after researchers first raised questions about possible links to heart attacks. After three years of debate, the FDA limited access to the drug in 2010.
But FDA regulators said Monday that a more recent analysis of a key Avandia study shows that the drug's heart risks are no greater than those of other diabetes drugs.
"Given these new results, our level of concern is considerably reduced," said FDA drug center director Dr. Janet Woodcock.
Dr. Steven Nissen of the Cleveland Clinic, whose research first raised concerns about Avandia, criticized the move. He said he doesn't expect doctors to return to prescribing it, since many newer diabetes drugs are now available.
