ROXYBOND vs STADOL PRESERVATIVE FREE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Butorphanol is a synthetic agonist-antagonist opioid analgesic that exerts its effects primarily through binding to kappa-opioid receptors and, to a lesser extent, mu-opioid receptors, producing analgesia and sedation. It also has partial antagonist activity at mu receptors.
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.
0.5–2 mg intravenously or intramuscularly every 3–4 hours as needed for pain. Alternatively, 1–2 mg as a single dose, may repeat in 30–60 minutes if needed.

3.5–6 hours; prolonged in renal impairment, hepatic impairment, or elderly patients, requiring dose adjustment.
Terminal elimination half-life is 2.5–3.3 hours in adults; prolonged to 4–6 hours in elderly or hepatic impairment.
Primarily renal (90% as free drug and glucuronide conjugates). Fecal elimination accounts for <10%.
Primarily hepatic metabolism (glucuronidation) to inactive metabolites; renal excretion accounts for <5% unchanged drug. Approximately 70% of dose excreted in urine as metabolites, 20% in feces.
