Hydromorphone extended release manufacturers

Two formulations of extended-release hydromorphone have been evaluated and filed for FDA approval in the USA. These formulations have been marketed under the names Palladone , manufactured by Purdue Pharma Inc., and Exalgo , produced by Neu-romed Pharmaceuticals Inc. Palladone was initially approved for sale in the USA in 2004, but was voluntarily withdrawn from the market due to safety concerns. Exalgo is currently in the final stages of FDA approval as a once-daily administered analgesic for the management of chronic pain.
