Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Mu-opioid receptor agonist; inhibits ascending pain pathways and alters pain perception and emotional response to pain.
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.
Initial: 8 mg orally every 24 hours for opioid-naive patients; titration based on response; maximum 32 mg daily.
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: approximately 15-18 hours in healthy adults. Steady state is achieved by 3-5 days. In patients with hepatic impairment, half-life may be prolonged up to 24-27 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.
Renal: primarily as hydromorphone-3-glucuronide and unchanged drug (~40% as glucuronide conjugates, ~3% as unchanged hydromorphone). Fecal: minimal. Total renal clearance accounts for ~50% of drug elimination.
Renal excretion: 70-80% as unchanged drug and metabolites (oxymorphone, noroxycodone); fecal: 10-20%.
