Web1 de jun. de 2008 · Concentrations of oxycodone and its metabolites noroxycodone, oxymorphone, and noroxymorphone were determined for 48 h. Psychomotor effects were characterized for 12 h by several visual analog scales. 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.
