DURAGESIC-25 vs FYREMADEL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fentanyl is a mu-opioid receptor agonist that produces analgesia and sedation by mimicking endogenous opioids in the central nervous system.
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.
Apply 25 mcg/hour transdermally every 72 hours; initial dose in opioid-naive patients: 25 mcg/hour is not recommended; use lower strength or immediate-release opioid first.
100 mg orally twice daily.
