In a GCMS, UDA Codeine, Hydrocodone, Oxycodone, Oxymorphone
, 6-acetyl <span style = 'background-color: #dae8f4'>morphine</span>
(Heroin metabolite) is
an unexpected result.
Another study: hydromorphone was detected in patients treated with high-dose morphine
. The ratio of hydromorphone to morphine
ranged from 0.2 to 2.2%. Oxymorphone was not detected in any specimen from high-dose morphine
or high-dose hydromorphone patients. The authors conclude, based on these data, that oxymorphone is not a metabolite of morphine
