NUCYNTA ER vs VICODIN
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.
VICODIN (hydrocodone/acetaminophen) is a combination opioid agonist and analgesic. Hydrocodone acts on mu-opioid receptors in the CNS to alter pain perception and response; acetaminophen inhibits cyclooxygenase (COX) activity, likely in the CNS, reducing prostaglandin synthesis and providing antipyretic effects.
100 mg orally every 12 hours, titrated from 50 mg every 12 hours; maximum 200 mg every 12 hours.
1-2 tablets (hydrocodone 5-10 mg and acetaminophen 300-325 mg) orally every 4-6 hours as needed for pain; maximum daily acetaminophen dose 4 g.

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: 3.8-6.4 hours (terminal); Acetaminophen: 2-3 hours (terminal). Clinically, steady-state achieved in 1-2 days.
Renal: 99% (tapentadol and glucuronide conjugates); Fecal: <1%; unchanged tapentadol: <5%.
Hydrocodone: primarily renal (~60% as metabolites, 12% unchanged); minor biliary. Acetaminophen: renal (90-100% as metabolites, 2-4% unchanged).
