Update on Embeda NDA Review

King Pharmaceuticals Provides Update on Embeda NDA Review

BRISTOL, Tenn.--(BUSINESS WIRE)--Dec 31, 2008 - King Pharmaceuticals, Inc. today announced that the U.S. Food and Drug Administration (FDA) is continuing its review of the New Drug Application (NDA) for Embeda (morphine sulfate and naltrexone hydrochloride) extended release capsules. It is likely that this review will extend into early 2009.

"Our discussions with the FDA continue to progress and we remain confident in the strength of our regulatory submission," said Eric Carter, Chief Science Officer of King Pharmaceuticals. "We look forward to working closely with the agency as needed throughout the review process."

About Embeda

Utilizing King's proprietary technology, Embeda Capsules contain extended-release morphine pellets, each with a sequestered core of naltrexone, an opioid antagonist. The formulation is designed to work such that if taken as directed, the morphine would relieve pain while the sequestered naltrexone would pass through the body with no observed clinical effect. If Embeda Capsules are crushed or chewed, the naltrexone would be released, mitigating the euphoric effect of the morphine.
