OPANA vs VICOPRIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Mu-opioid receptor agonist; produces analgesia by binding to opioid receptors in the CNS, inhibiting ascending pain pathways and altering pain perception.
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.
5-20 mg orally every 4-6 hours as needed for pain; extended-release tablets: 5 mg orally every 12 hours, titrated up to 20 mg every 12 hours.
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.

Terminal elimination half-life is 11-16 hours (mean 14 hours) in adults; prolonged in hepatic impairment (up to 30 hours) and elderly.
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 (approximately 90% as conjugated metabolites, 10% unchanged); biliary/fecal elimination accounts for <10%.
Renal excretion of metabolites (hydrocodone: ~60% as conjugates; acetaminophen: ~85-90% as glucuronide and sulfate conjugates). Biliary/fecal elimination accounts for <5%.
