WASHINGTON — The Food and Drug Administration has approved a stronger, single-ingredient version of the painkiller hydrocodone, the widely abused prescription medicine for chronic pain.
The agency said Friday it approved the pill Zohydro for patients with pain that requires ‘‘daily, around-the-clock, long-term treatment’’ that cannot be addressed with other drugs.
Hydrocodone is currently sold in combination pills like Vicodin to treat pain from injuries, surgery, arthritis, migraines and other ailments. The new drug from Zogenix is the first pure, non-combination form of the drug approved in the United States.
The approval came as a surprise since the agency’s own panel of outside advisers gave the drug an overwhelmingly negative review last year. Full story for BostonGlobe.com subscribers.
