EXALGO vs VICOPRIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Mu-opioid receptor agonist; inhibits ascending pain pathways and alters pain perception and emotional response to pain.
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.
Initial: 8 mg orally every 24 hours for opioid-naive patients; titration based on response; maximum 32 mg daily.
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: approximately 15-18 hours in healthy adults. Steady state is achieved by 3-5 days. In patients with hepatic impairment, half-life may be prolonged up to 24-27 hours.
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: primarily as hydromorphone-3-glucuronide and unchanged drug (~40% as glucuronide conjugates, ~3% as unchanged hydromorphone). Fecal: minimal. Total renal clearance accounts for ~50% of drug elimination.
Renal excretion of metabolites (hydrocodone: ~60% as conjugates; acetaminophen: ~85-90% as glucuronide and sulfate conjugates). Biliary/fecal elimination accounts for <5%.
