The FDA approved a unique warning label for OxyContin. It allowed Purdue to claim that OxyContin had a lower potential for abuse than other oxycodone products because its timed-release formula allowed for a delay in absorbing the drug. “No other manufacturer of a Schedule II narcotic ever got the go-ahead from the FDA to make such a claim,” Meier wrote. “It was a claim that soon became a cornerstone of the marketing of OxyContin.”
