DOLENE vs PROPOXYPHENE HYDROCHLORIDE 65
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Opioid agonist, primarily mu-opioid receptor activation, leading to analgesic and euphoric effects.
Propoxyphene is a centrally acting opioid agonist that binds to mu-opioid receptors in the central nervous system, inhibiting pain signal transmission and altering pain perception. It also has local anesthetic effects.
50 mg orally every 4-6 hours as needed for pain; maximum 400 mg per day.
65 mg orally every 4 hours as needed for pain; maximum 390 mg/day.

2.5-3.5 hours; prolonged in hepatic impairment (up to 6-8 hours) and in neonates.
6-12 hours (mean ~8 hours); prolonged in hepatic impairment and elderly; accumulation possible with repeated dosing.
Renal: 70-80% as conjugated metabolites (mostly glucuronides), 5-10% as unchanged drug; Fecal: 5-10%; Biliary: minor.
Renal excretion of unchanged drug (approximately 20-30%) and metabolites; approximately 40-60% as conjugated metabolites; minor biliary/fecal elimination.
