Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fentanyl is a potent mu-opioid receptor agonist, producing analgesia and sedation by activating G-protein coupled opioid receptors in the central nervous system.
Selective, high-affinity agonist at the mu-opioid receptor, resulting in analgesia via activation of G-protein coupled inwardly rectifying potassium channels and inhibition of voltage-gated calcium channels in the central nervous system.
For breakthrough pain in opioid-tolerant patients: initial dose 100 mcg sublingual tablet, titrate across strengths (100, 200, 300, 400, 600, 800 mcg) as needed; maximum 2 doses per episode, minimum 2 hours between episodes.
30 mcg sublingual tablet as a single dose; may repeat once after 1 hour if needed. Maximum 2 doses per 24 hours.

Terminal elimination half-life: 6-10 hours (mean 8 hours); prolonged in elderly and hepatic impairment
Terminal elimination half-life is approximately 23.4 hours (range 17–30 h), supporting once-daily dosing. Due to rapid redistribution, clinical effects may wane before elimination is complete.
Renal: ~70% as metabolites (primarily fentanyl conjugates and norfentanyl), ~10% unchanged; Fecal: ~9%; Biliary: minimal
Primarily renal elimination of metabolites; unchanged drug accounts for <1% of the dose. Fecal excretion is minimal. Total recovery: ~70% in urine, ~20% in feces.
