The metamorphosis of hydromorphone

Abstract

Hydromorphone, one of the oldest and most potent of opioids, is an effective alternative to morphine. With a variety of routes of administration, it has an efficacy similar to that of morphine. The FDA has recently approved the first commercially available extended-release formulation, a once-daily hydromorphone for the management of moderate to severe pain in opioid tolerant individuals with an anticipated extended period of use. The formulation exhibits less peak-to-trough fluctuation in plasma concentration, while providing analgesia statistically indistinguishable from its immediate-release counterpart. The manufacturer and the FDA have articulated a plan to minimize unskillful prescribing and abuse/diversion through education, supply-chain integrity, and surveillance. It is anticipated that Palladone will be a valuable addition to the limited armamentarium of extended-release opioids.
