DURAGESIC-25 vs LERITINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fentanyl is a mu-opioid receptor agonist that produces analgesia and sedation by mimicking endogenous opioids in the central nervous system.
LERITINE (anileridine) is a synthetic opioid analgesic that acts as a mu-opioid receptor agonist, modulating pain perception and emotional response to pain.
Apply 25 mcg/hour transdermally every 72 hours; initial dose in opioid-naive patients: 25 mcg/hour is not recommended; use lower strength or immediate-release opioid first.
Adults: 25-50 mg orally every 6 hours as needed for pain; not to exceed 200 mg/day.
