LERITINE vs PROPOXYPHENE HYDROCHLORIDE
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.
Propoxyphene hydrochloride is a centrally acting opioid analgesic that binds to mu-opioid receptors in the central nervous system, inhibiting ascending pain pathways and altering perception of and response to pain.
Adults: 25-50 mg orally every 6 hours as needed for pain; not to exceed 200 mg/day.
65 mg orally every 4 hours as needed for pain; maximum 390 mg per day.

2-3 hours (terminal half-life in adults; may be prolonged in hepatic impairment or elderly, dosing adjustments recommended)
6–12 hours (parent drug); norpropoxyphene metabolite half-life 30–36 hours, accumulates with repeated dosing, increasing risk of toxicity, especially in elderly or renal impairment.
Renal (70-90% as unchanged drug and metabolites); biliary/fecal (10-30%)
Primarily renal (70-90% as unchanged drug and metabolites, including norpropoxyphene); biliary/fecal excretion accounts for less than 10%.
