DURADYNE DHC vs OXAYDO
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 relative selectivity for mu-opioid receptors, although it can bind to kappa-opioid receptors at higher doses. The principal therapeutic action of oxycodone is analgesia. Like all full opioid agonists, there is no ceiling effect to analgesia for oxycodone.
1 tablet (10 mg hydrocodone/300 mg acetaminophen) orally every 4-6 hours as needed for pain; maximum 8 tablets per day.
Oral, 5-10 mg every 4-6 hours as needed for pain; maximum 60 mg per 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 3.5-5.5 hours for immediate-release oxycodone; clinically dose every 4-6 hours for sustained analgesia.
Primarily renal excretion of metabolites; ~90% excreted in urine as glucuronide conjugates and morphine; ~10% in feces via bile.
Primarily renal as unchanged drug and metabolites; ~90% excreted in urine (approx 10% unchanged oxycodone, rest as noroxycodone and oxymorphone conjugates) and <10% in feces via biliary elimination.
