DURADYNE DHC vs ROXICODONE
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.
Oxycodone is a full opioid agonist with high affinity for mu-opioid receptors, also binding to kappa and delta receptors. It acts primarily on the central nervous system and gastrointestinal tract.
1 tablet (10 mg hydrocodone/300 mg acetaminophen) orally every 4-6 hours as needed for pain; maximum 8 tablets per day.
5-15 mg orally every 4-6 hours as needed for pain; immediate-release formulation. Maximum 60 mg total daily dose for opioid-naive patients.

Terminal elimination half-life of dihydrocodeine is approximately 4 hours; clinically relevant for dosing interval of 4-6 hours.
3.5-5 hours for immediate-release; 4.5-5.5 hours for extended-release. Accumulation may occur with repeated dosing, especially in elderly or hepatic impairment.
Primarily renal excretion of metabolites; ~90% excreted in urine as glucuronide conjugates and morphine; ~10% in feces via bile.
Renal excretion: 70-80% as unchanged drug and metabolites (oxymorphone, noroxycodone); fecal: 10-20%.
