Noroxymorphone metabolites
WebIn clinical work, active metabolites have no or only a small role in the analgesic efficacy of oxycodone. After peripheral oxycodone administration oxymorphone is produced in a minor amount, less than 5% of the parent drug is metabolized to oxymorphone, and thus plasma circulating oxymorphone concentrations are very low.
