NUCYNTA ER vs VICOPRIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Tapentadol is a mu-opioid receptor agonist and norepinephrine reuptake inhibitor, providing analgesic effects through opioid receptor activation and modulation of descending pain pathways.
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.
100 mg orally every 12 hours, titrated from 50 mg every 12 hours; maximum 200 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: 4.1 hours (range 3.3–4.7 h) after single oral dose; steady state: 4.4 h. No clinically relevant accumulation.
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: 99% (tapentadol and glucuronide conjugates); Fecal: <1%; unchanged tapentadol: <5%.
Renal excretion of metabolites (hydrocodone: ~60% as conjugates; acetaminophen: ~85-90% as glucuronide and sulfate conjugates). Biliary/fecal elimination accounts for <5%.
