DOLENE vs MS CONTIN
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.
Mu-opioid receptor agonist; binds to mu-opioid receptors in the CNS, modulating pain perception and emotional response to pain.
50 mg orally every 4-6 hours as needed for pain; maximum 400 mg per day.
Oral: 15-30 mg every 8-12 hours; adjust based on pain severity and prior opioid use. Extended-release tablets must be swallowed whole; do not crush or chew. For opioid-naïve patients, start at 15 mg every 12 hours.

2.5-3.5 hours; prolonged in hepatic impairment (up to 6-8 hours) and in neonates.
Terminal elimination half-life: 11-13 hours (range 8-24 hours). In elderly or hepatic impairment, half-life may be prolonged; acute dosing half-life ~2-4 hours.
Renal: 70-80% as conjugated metabolites (mostly glucuronides), 5-10% as unchanged drug; Fecal: 5-10%; Biliary: minor.
Renal: ~90% (mostly as morphine-3-glucuronide and morphine-6-glucuronide, with ~10% as unchanged morphine); Fecal: <10%
