FDA bans copycat versions of original Oxy amid abuse concerns

DRUG BANNEDThe U.S. Food and Drug Administration said Tuesday it will not approve any generic versions of OxyContin based on the powerful painkiller’s original formulation, which does not include anti-abuse features designed to make the pill harder to abuse.

According to the agency, “because original OxyContin provides the same therapeutic benefits as reformulated OxyContin, but poses an increased potential for certain types of abuse, the FDA has determined that the benefits of original OxyContin no longer outweigh its risks and that original OxyContin was withdrawn from sale for reasons of safety or effectiveness.”

OxyContin’s manufacturer, Purdue Pharma, reformulated the drug in 2010 to make it more difficult to crush, break, or dissolve; the reformulated pill forms a viscous hydrogel and cannot be easily prepared for injection. The FDA noted Tuesday that abuse of OxyContin by these routes, as well as the oral route, is still possible.

The FDA’s decision came on the same day that Purdue’s patent on the original OxyContin expired, which normally opens the door for generic drug makers to launch their own cheaper versions of a product. Now, these generic companies will have to develop their own abuse-deterrent designs, preserving Purdue’s monopoly on the OxyContin market for the time being.

OxyContin, which first hit the market in 1995, raked in more than $2.8 billion in sales last year. The company pleaded guilty in 2007 to mismarketing the drug as less addictive and less subject to abuse than other pain medicines and paid $635 million in fines.

Critics have raised concerns that the FDA’s decision to bar generic OxyContin may push patients towards less effective drugs without eliminating the risk of addiction, or that generic companies may rush to create abuse-deterrent versions and falsely market to prescribers that these pills are less addictive.

In addition, about one-quarter of abusers say they’ve figured out how to defeat the anti-abuse mechanisms, according to a 2012 article in the New England Journal of Medicine.
