FDA approves abuse-deterrent labeling for reformulated OxyContin
Agency will not approve generics to original OxyContin
The U.S. Food and Drug Administration today approved updated labeling for Purdue Pharma L.P.'s reformulated OxyContin (oxycodone hydrochloride controlled-release) tablets. The new labeling indicates that the product has physical and chemical properties that are expected to make abuse via injection difficult and to reduce abuse via the intranasal route (snorting).
Additionally, 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FDA has determined that the benefits of original OxyContin no longer outweigh its risks and that original OxyContin was withdrawn from sale for reasons of safety or effectiveness. Accordingly, the agency will not accept or approve any abbreviated new drug applications (generics) that rely upon the approval of original OxyContin.
The FDA approved the original formulation of OxyContin in Dec. 1995. The product was abused, often following manipulation intended to defeat its extended-release properties. Such manipulation causes the drug to be released more rapidly, which increases the risk of serious adverse events, including overdose and death. In April 2010, the FDA approved a reformulated version of OxyContin, which was designed to be more difficult to manipulate for purposes of misuse or abuse. Purdue stopped shipping original OxyContin to pharmacies in August 2010.
"The development of abuse-deterrent opioid analgesics is a public health priority for the FDA," said Douglas Throckmorton, M.D., deputy director for regulatory programs in the FDA's Center for Drug Evaluation and Research. "While both original and reformulated OxyContin are subject to abuse and misuse, the FDA has determined that reformulated OxyContin can be expected to make abuse by injection difficult and expected to reduce abuse by snorting compared to original OxyContin."
