Hydromorphone-OROS formulation.

IMPORTANCE TO THE FIELD: Hydromorphone is a semi-synthetic opioid approved in the USA for the treatment and relief of moderate to severe pain and postoperative pain. However, the compound is short-acting, and there is no extended-release formulation clinically available. A previous hydromorphone extended-release formulation that successfully came to market was subsequently withdrawn on account of safety concerns. Clinical need supports the presence of an extended-release formulation of hydromorphone.
