“U.S. health regulators announced that they will not approve any generic versions of the original form of the pain medication OxyContin, which was widely abused because it could be crushed and then snorted or injected to produce a quick high.
At the same time, the Food and Drug Administration also approved new labeling for a reformulated OxyContin, which was introduced by privately held manufacturer Purdue Pharma L.P. in 2010. The label will indicate that the tablets’ physical and chemical properties make them more difficult to crush, meaning that abuse is less likely than with the original.”
