DOLENE vs OXYCONTIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Opioid agonist, primarily mu-opioid receptor activation, leading to analgesic and euphoric effects.
Oxycodone is a full opioid agonist with relative selectivity for the mu-opioid receptor, although it can bind to other opioid receptors at higher doses. The principal therapeutic action of oxycodone is analgesia. Like all full opioid agonists, there is no ceiling effect for analgesia with oxycodone. Clinically, dosage is titrated to provide adequate analgesia and may be limited by adverse reactions, including respiratory and CNS depression.
50 mg orally every 4-6 hours as needed for pain; maximum 400 mg per day.
10 mg orally every 12 hours; titrate based on pain severity and prior opioid exposure.

2.5-3.5 hours; prolonged in hepatic impairment (up to 6-8 hours) and in neonates.
4.5-5.0 hours (immediate-release); controlled-release OXYCONTIN has an apparent half-life of 4.5-8.7 hours. Terminal half-life is ~3.5-4 hours for immediate-release, reflecting context-sensitive elimination.
Renal: 70-80% as conjugated metabolites (mostly glucuronides), 5-10% as unchanged drug; Fecal: 5-10%; Biliary: minor.
Primarily renal (90% as metabolites, 10% unchanged). Also biliary/fecal (10%).
