OXYCONTIN vs PALLADONE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Agonist at mu-opioid receptors, modulating pain perception via central and peripheral pathways.
10 mg orally every 12 hours; titrate based on pain severity and prior opioid exposure.
Immediate-release: 4-8 mg orally every 4-6 hours as needed for pain; extended-release: 8 mg orally every 12 hours, titrated based on response and tolerance.

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.
Terminal elimination half-life is approximately 18 hours (range 12-24 h); supports extended dosing intervals.
Primarily renal (90% as metabolites, 10% unchanged). Also biliary/fecal (10%).
Primarily renal (90%) as unchanged drug and glucuronide conjugate; ~10% biliary/fecal.
