LERITINE vs SUBLIMAZE PRESERVATIVE FREE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
LERITINE (anileridine) is a synthetic opioid analgesic that acts as a mu-opioid receptor agonist, modulating pain perception and emotional response to pain.
Fentanyl is a potent synthetic opioid agonist with primary action at the mu-opioid receptor. It induces analgesia, sedation, and respiratory depression by activating G-protein-coupled receptors that inhibit adenylyl cyclase, reduce cAMP production, and modulate ion channels (e.g., potassium efflux, calcium influx).
Adults: 25-50 mg orally every 6 hours as needed for pain; not to exceed 200 mg/day.
IV: 0.5-2 mcg/kg bolus, may repeat q2-4h; or 0.5-1 mcg/kg/h infusion; IM: 0.5-2 mcg/kg q1-2h prn.

2-3 hours (terminal half-life in adults; may be prolonged in hepatic impairment or elderly, dosing adjustments recommended)
Terminal elimination half-life is 3-7 hours (mean 4.5 h) after IV administration, but may be prolonged (up to 12-15 h) in elderly, hepatic impairment, or after prolonged infusion due to redistribution.
Renal (70-90% as unchanged drug and metabolites); biliary/fecal (10-30%)
Primarily renal: fentanyl and its metabolites are excreted in urine (~75%) and feces (~9%). Less than 10% excreted unchanged.
