pigrabbitbear writes "The active ingredient in OxyContin, oxycodone, isn't a new compound. It was originally synthesized in Germany in 1916. The patent on the medication had expired well before Purdue Pharma, a Stamford, Connecticut-based pharmaceutical company and the industry leader in pain medication, released it under the brand name in 1996. The genius of Purdue's continued foray into pain-management medication – they had already produced versions of hydromorphone, oxycodone, fentanyl, codeine, and hydrocodone – was twofold. They not only created a drug from an already readily available compound, but they were able to essentially re-patent the active ingredient by introducing a time-release element. Prior to the 1990s, strong opioid medications were not routinely given for miscellaneous or chronic, moderately painful conditions; the strongest classes of drugs were often reserved for the dying. But Purdue parlayed their time-release system not only into the patent for OxyContin. They also went on a PR blitz, claiming their drug was unique because of the time-release element and implied that it was so difficult to abuse that the risk of addiction was 'under 1%.'"
