NUBAIN vs VICOPRIN
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.
VICOPRIN (hydrocodone/acetaminophen) combines a mu-opioid receptor agonist (hydrocodone) that inhibits ascending pain pathways and alters pain perception, with an analgesic and antipyretic (acetaminophen) that inhibits cyclooxygenase (COX) and central prostaglandin synthesis.
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.
1 to 2 tablets (each containing 7.5 mg hydrocodone bitartrate and 200 mg ibuprofen) orally every 4 to 6 hours as needed for pain; maximum 5 tablets per day.

3.5–5 hours (terminal elimination half-life); clinically, in hepatic or renal impairment, half-life may be prolonged, requiring dose adjustment.
Hydrocodone: 3.8-6.0 hours in adults; acetaminophen: 2.0-4.0 hours. Clinically, Vicoprofen (hydrocodone/ibuprofen) has an effective half-life of ~4-6 hours for hydrocodone; ibuprofen half-life is 2-4 hours.
Primarily renal (83% as unchanged drug and glucuronide conjugate); fecal excretion accounts for <5%.
Renal excretion of metabolites (hydrocodone: ~60% as conjugates; acetaminophen: ~85-90% as glucuronide and sulfate conjugates). Biliary/fecal elimination accounts for <5%.
