BUTRANS vs VICOPRIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Buprenorphine is a partial mu-opioid receptor agonist and a weak kappa-opioid receptor antagonist. It binds with high affinity to mu-opioid receptors, producing analgesic and opioid effects with a ceiling effect on 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.
Apply one BUTRANS (buprenorphine) transdermal system to a clean, dry, non-irritated, and non-hairy area of the chest, back, flank, or upper arm. Initial dose: 5 mcg/h for opioid-naïve patients; titrate based on pain control and tolerability. Maximum dose: 20 mcg/h. Replace every 7 days. Rotate application sites.
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 half-life: 4-6 hours in healthy adults; prolonged to 12-18 hours in elderly or renal 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: 60-70% as unchanged drug and metabolites; biliary/fecal: 20-30%
Renal excretion of metabolites (hydrocodone: ~60% as conjugates; acetaminophen: ~85-90% as glucuronide and sulfate conjugates). Biliary/fecal elimination accounts for <5%.
