NUBAIN vs VICODIN ES
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nalbuphine is a mixed opioid agonist-antagonist. It acts as an agonist at kappa opioid receptors and as an antagonist at mu opioid receptors, providing analgesia with a ceiling effect for respiratory depression.
Hydrocodone is a mu-opioid receptor agonist; acetaminophen inhibits cyclooxygenase (COX) and modulates descending serotonergic pathways.
10-20 mg IV, IM, or SC every 3-6 hours as needed for pain; maximum single dose 20 mg, maximum daily dose 160 mg.
Oral: 1 tablet (7.5 mg hydrocodone/300 mg acetaminophen) every 4-6 hours as needed for pain; maximum 6 tablets per day due to acetaminophen limit.

3.5–5 hours (terminal elimination half-life); clinically, in hepatic or renal impairment, half-life may be prolonged, requiring dose adjustment.
Hydrocodone: terminal half-life approximately 3.3-4.5 hours in adults, extended in hepatic or renal impairment. Acetaminophen: terminal half-life about 2-3 hours.
Primarily renal (83% as unchanged drug and glucuronide conjugate); fecal excretion accounts for <5%.
Hydrocodone: primarily renal (urine) as unchanged drug and metabolites (O-demethylation and 6-keto-reduction products); ~26% excreted unchanged. Acetaminophen: renal (urine), ~85% as glucuronide and sulfate conjugates, ~2% unchanged.
