1 Hydromorphone is a minor metabolite of morphine and may be excreted in urine at concentrations up to 2.5% of the morphine concentration. 2  Consequently, the detection of minor amounts of hydromorphone in urine containing high concentrations of codeine should not be interpreted as evidence of hydromorphone use.
7.5 mg of hydrocodone equals 5 mg of oxycodone. At least that's as close as you can get to equal analgesic dosage. Hydrocodone does metabolise into hydromorphone, which is what binds to the opiate receptors in the cns. Hydrocodone has no pharmacological action on its own. Oxycodone on the other hand, provides pharmacological action of its own.
