FYREMADEL vs LAZANDA
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.
Fentanyl is a μ-opioid receptor agonist. It binds to μ-opioid receptors in the central nervous system, activating G-protein-coupled receptors to inhibit adenylate cyclase, reduce cAMP production, and modulate ion channels, leading to decreased neurotransmitter release (e.g., substance P, glutamate) and hyperpolarization of neurons, resulting in analgesia and sedation.
100 mg orally twice daily.
100 mcg (one spray) intranasally as needed for breakthrough pain; may repeat once after 15-30 minutes if needed; do not exceed 2 doses per episode and 4 doses per day.

Terminal half-life: 12 hours (range 8–16 h) in healthy adults; prolonged in hepatic impairment.
Terminal elimination half-life: 6–10 hours (mean approximately 7 hours) following nasal administration; prolonged in hepatic impairment.
Renal: 60% unchanged; Biliary/Fecal: 30% as metabolites; 10% other.
Renal excretion of metabolites (mostly fentanyl metabolites, primarily norfentanyl): approximately 75%; fecal excretion: approximately 9%; less than 10% excreted as unchanged fentanyl in urine.
