ROXICODONE vs VICOPRIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Oxycodone is a full opioid agonist with high affinity for mu-opioid receptors, also binding to kappa and delta receptors. It acts primarily on the central nervous system and gastrointestinal tract.
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.
5-15 mg orally every 4-6 hours as needed for pain; immediate-release formulation. Maximum 60 mg total daily dose for opioid-naive patients.
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 for immediate-release; 4.5-5.5 hours for extended-release. Accumulation may occur with repeated dosing, especially in elderly or hepatic impairment.
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.
Renal excretion: 70-80% as unchanged drug and metabolites (oxymorphone, noroxycodone); fecal: 10-20%.
Renal excretion of metabolites (hydrocodone: ~60% as conjugates; acetaminophen: ~85-90% as glucuronide and sulfate conjugates). Biliary/fecal elimination accounts for <5%.
