On December 12, 1995, the Food and Drug Administration approved the opioid analgesic OxyContin. It hit the market in 1996. In its first year, OxyContin accounted for $45 million in sales for its manufacturer, Stamford, Connecticut-based pharmaceutical company Purdue Pharma. By 2000 that number would balloon to $1.1 billion, an increase of well over 2,000 percent in a span of just four years.
