Detection and quantification of hydrocodone, norhydrocodone, and hydromorphone in urine
Hydrocodone exhibits a complex pattern of metabolism including O-demethylation, N-demethylation, and 6-keto reduction to the 6-beta hydroxymetabolites. Hydromorphone and norhydrocodone are both metabolites of hydrocodone. Dihydrocodeine is also a minor metabolite. Trace amounts of hydrocodone can also be found in the presence of approximately 100-fold higher concentrations of oxycodone or hydromorphone since it can be a pharmaceutical impurity in these medications. The presence of hydrocodone indicates exposure within 2 to 3 days prior to specimen collection.
Hydromorphone is metabolized primarily in the liver and is excreted primarily as the glucuronidated conjugate, with small amounts of parent drug and minor amounts of 6-hydroxy reduction metabolites. The presence of hydromorphone indicates exposure within 2 to 3 days prior to specimen collection. Hydromorphone is also a metabolite of hydrocodone; therefore, the presence of hydromorphone could also indicate exposure to hydrocodone.
The detection interval for the opiates is generally 2 to 3 days after last ingestion.
Negative
Cutoff concentrations-liquid chromatography tandem mass spectrometry:
Hydrocodone: 25 ng/mL
Norhydrocodone: 25 ng/mL
Hydromorphone: 25 ng/mL
This procedure reports the total urine concentration; this is the sum of the unconjugated and conjugated forms of the parent drug.
Other drugs in the opioid class, such as fentanyl, meperidine, methadone, and opiate antagonists such as naloxone, are not detected
