OXAYDO vs SUFENTA PRESERVATIVE FREE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
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.
Oral, 5-10 mg every 4-6 hours as needed for pain; maximum 60 mg per day.
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.

Terminal elimination half-life is 3.5-5.5 hours for immediate-release oxycodone; clinically dose every 4-6 hours for sustained analgesia.
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).
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.
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%).
