FYREMADEL vs OXYMORPHONE HYDROCHLORIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
FYREMADEL is a GLP-1 receptor agonist that activates GLP-1 receptors, increasing insulin secretion and decreasing glucagon secretion in a glucose-dependent manner, and slows gastric emptying.
Oxymorphone is a semi-synthetic opioid agonist that binds to mu-opioid receptors in the central nervous system, inhibiting ascending pain pathways and altering pain perception and response. It also has affinity for kappa and delta opioid receptors.
100 mg orally twice daily.
Initial: 1 mg IV/IM every 3-4 hours as needed for moderate to severe pain; titrate to effect. For patient-controlled analgesia (PCA), 0.5 mg IV loading dose, then 0.25-0.5 mg every 6-15 minutes with lockout. Rectal suppository: 5 mg every 4-6 hours.

Terminal half-life: 12 hours (range 8–16 h) in healthy adults; prolonged in hepatic impairment.
Terminal elimination half-life: 7-9 hours (range 4-12 h in elderly/renal impairment). Clinically, steady-state achieved within 24-36 hours.
Renal: 60% unchanged; Biliary/Fecal: 30% as metabolites; 10% other.
Primarily renal (90% as parent drug and metabolites); <1% fecal. Unchanged oxymorphone accounts for ~30% of urinary recovery.
