NORCO vs NUCYNTA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
NORCO is a combination of hydrocodone, a mu-opioid receptor agonist that inhibits ascending pain pathways and alters pain perception, and acetaminophen, which inhibits cyclooxygenase (COX) enzymes, particularly in the CNS, leading to decreased prostaglandin synthesis and antipyresis.
Tapentadol is a centrally acting analgesic with dual mechanisms of action: mu-opioid receptor agonism and norepinephrine reuptake inhibition.
One tablet (5 mg hydrocodone/325 mg acetaminophen, 7.5 mg/325 mg, 10 mg/325 mg) orally every 4-6 hours as needed for pain. Maximum acetaminophen dose 4000 mg/day; maximum hydrocodone dose 60 mg/day.
50-100 mg orally every 4-6 hours as needed for pain; maximum 600 mg/day.

Hydrocodone: terminal elimination half-life is 3.8 to 6.0 hours (mean 4.5 hours) in adults; prolonged in hepatic or renal impairment. Acetaminophen: half-life 1.5–3 hours.
Terminal elimination half-life is approximately 4 hours (range 3-5 hours); no significant accumulation with repeated dosing at recommended intervals.
Hydrocodone: primarily renal (approximately 60% as unchanged drug and metabolites, including norhydrocodone, hydromorphone, and conjugated metabolites). Biliary/fecal excretion accounts for <10%.
Primarily renal excretion (approximately 95% of the dose is excreted in urine as tapentadol and its conjugates; <1% excreted unchanged in feces).
