DURAGESIC-75 vs VICODIN HP
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fentanyl is a potent opioid agonist primarily at the mu-opioid receptor, exerting its analgesic effects by mimicking endogenous endorphins and enkephalins to activate G-protein-coupled inwardly rectifying potassium channels, leading to hyperpolarization and reduced neuronal excitability in pain pathways.
Hydrocodone is a mu-opioid receptor agonist that inhibits ascending pain pathways; acetaminophen inhibits cyclooxygenase and has antipyretic effects.
Adults: Apply one 75 mcg/hr transdermal patch every 72 hours. Start with lower dose in opioid-naive patients.
One tablet (hydrocodone bitartrate 10 mg/acetaminophen 660 mg) orally every 4-6 hours as needed for pain; maximum 6 tablets per day.

22-25 hours after removal of patch; increased in elderly, hepatic/renal impairment
Hydrocodone: 3.8-5.5 hours (mean 4.5 h). Acetaminophen: 2-3 hours. Clinical context: dosing interval every 4-6 hours for acute pain.
Renal (75% as metabolites, <10% unchanged), fecal (25%)
Primarily renal: hydrocodone is eliminated as conjugated metabolites (glucuronides) ~80%; unchanged drug ~5%. Biliary/fecal: minor, <10%.
