Hydromorphone has been shown to be a minor metabolite in chronic pain patients receiving high amounts of morphine.4,5 Hydrocodone has been shown to be a minor metabolite detectable in patients on high amounts of codeine6; as the metabolite of hydrocodone, hydromorphone may also be detectable in these cases.

CYP3A4 mediated N-demethylation to norhydrocodone is the primary metabolic pathway of hydrocodone with a lower contribution from CYP2D6 mediated O- demethylation to hydromorphone. Hydromorphone is formed from the O-demethylation of hydrocodone and may contribute to the total analgesic effect of hydrocodone. Therefore,

hydrocodone or morphine and then to dihydrocodeine and hydromorphone. Heroin is metabolized to morphine. All of these will be identified as opiates on the basic UDS. Oxycodone is metabolized to oxymorphone; these will be identified as oxycodone on immunoassay UDS. It is therefore important to consider drug metabolism in interpreting UDS test ...

Metabolism Hydromorphone is extensively metabolized via glucuronidation in the liver, with greater than 95% of the dose metabolized to hydromorphone-3-glucuronide along with minor amounts of 6-hydroxy reduction metabolites. Elimination Only a small amount of the hydromorphone dose is excreted unchanged in the urine. Most
