MS CONTIN vs ROXYBOND
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Mu-opioid receptor agonist; binds to mu-opioid receptors in the CNS, modulating pain perception and emotional response to pain.
ROXYBOND is an immediate-release formulation of oxycodone, a full mu-opioid receptor agonist. It binds to mu-opioid receptors in the central nervous system (CNS), inhibiting ascending pain pathways and altering pain perception and emotional response to pain.
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.
Immediate-release oral tablets: 5-15 mg every 4-6 hours as needed for pain. Maximum 60 mg/day. For extended-release: 10-20 mg every 12 hours, adjusted based on prior opioid use.

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.
3.5–6 hours; prolonged in renal impairment, hepatic impairment, or elderly patients, requiring dose adjustment.
Renal: ~90% (mostly as morphine-3-glucuronide and morphine-6-glucuronide, with ~10% as unchanged morphine); Fecal: <10%
Primarily renal (90% as free drug and glucuronide conjugates). Fecal elimination accounts for <10%.
