Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Sufentanil is a synthetic opioid analgesic that acts as a selective agonist at mu-opioid receptors in the central nervous system, leading to activation of descending pain pathways and inhibition of nociceptive transmission.
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.
1-2 mcg/kg IV initially, then 0.15-0.3 mcg/kg/min IV infusion; doses up to 8 mcg/kg for anesthesia induction.

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.
Terminal elimination half-life is approximately 2.5-3.5 hours in adults, 3-4 hours in neonates; clinical context: context-sensitive half-life increases with infusion duration (e.g., ~30 minutes after 2-hour infusion, ~45 min after 8-hour infusion).
Renal excretion: 70-80% as unchanged drug and metabolites (oxymorphone, noroxycodone); fecal: 10-20%.
Renal (metabolites, <1% unchanged) and biliary; sufentanil is extensively metabolized in liver via N-dealkylation and O-demethylation, with metabolites primarily excreted in urine (approximately 80%) and feces (approximately 20%).
