DURADYNE DHC vs NUCYNTA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
DURADYNE DHC contains dihydrocodeine, an opioid agonist that binds to mu-opioid receptors in the CNS, inhibiting ascending pain pathways and altering pain perception and response.
Tapentadol is a centrally acting analgesic with dual mechanisms of action: mu-opioid receptor agonism and norepinephrine reuptake inhibition.
1 tablet (10 mg hydrocodone/300 mg acetaminophen) orally every 4-6 hours as needed for pain; maximum 8 tablets per day.
50-100 mg orally every 4-6 hours as needed for pain; maximum 600 mg/day.

Terminal elimination half-life of dihydrocodeine is approximately 4 hours; clinically relevant for dosing interval of 4-6 hours.
Terminal elimination half-life is approximately 4 hours (range 3-5 hours); no significant accumulation with repeated dosing at recommended intervals.
Primarily renal excretion of metabolites; ~90% excreted in urine as glucuronide conjugates and morphine; ~10% in feces via bile.
Primarily renal excretion (approximately 95% of the dose is excreted in urine as tapentadol and its conjugates; <1% excreted unchanged in feces).
