Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fentanyl is a μ-opioid receptor agonist. It binds to μ-opioid receptors in the central nervous system, activating G-protein-coupled receptors to inhibit adenylate cyclase, reduce cAMP production, and modulate ion channels, leading to decreased neurotransmitter release (e.g., substance P, glutamate) and hyperpolarization of neurons, resulting in analgesia and sedation.
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.
100 mcg (one spray) intranasally as needed for breakthrough pain; may repeat once after 15-30 minutes if needed; do not exceed 2 doses per episode and 4 doses per day.
Oral, 5-10 mg every 4-6 hours as needed for pain; maximum 60 mg per day.

Terminal elimination half-life: 6–10 hours (mean approximately 7 hours) following nasal administration; prolonged in hepatic impairment.
Terminal elimination half-life is 3.5-5.5 hours for immediate-release oxycodone; clinically dose every 4-6 hours for sustained analgesia.
Renal excretion of metabolites (mostly fentanyl metabolites, primarily norfentanyl): approximately 75%; fecal excretion: approximately 9%; less than 10% excreted as unchanged fentanyl in urine.
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.
