The FDA ruled that makers of generics can continue producing versions of the painkiller Opana ER's older formulation, saying the new version is not a significant improvement when it comes to stopping drug abuse compared with earlier forms that are not abuse-deterrent.

The ruling is expected to raise concerns with some law-enforcement and community groups fighting drug abuse.
