NORCET vs VICOPRIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Combination analgesic: hydrocodone acts as a μ-opioid receptor agonist; acetaminophen inhibits cyclooxygenase (COX) and modulates endocannabinoid system, exerting central analgesic and antipyretic effects.
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.
1-2 tablets (containing paracetamol 325 mg and tramadol 37.5 mg) orally every 4-6 hours as needed for pain, maximum 8 tablets per day.
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.

2-4 hours (terminal); prolonged in hepatic impairment (up to 8-10 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.
Renal: ~60% unchanged; hepatic metabolism to inactive glucuronide conjugates; biliary/fecal: <5%
Renal excretion of metabolites (hydrocodone: ~60% as conjugates; acetaminophen: ~85-90% as glucuronide and sulfate conjugates). Biliary/fecal elimination accounts for <5%.
