BUTRANS vs FYREMADEL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Buprenorphine is a partial mu-opioid receptor agonist and a weak kappa-opioid receptor antagonist. It binds with high affinity to mu-opioid receptors, producing analgesic and opioid effects with a ceiling effect on respiratory depression.
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 one BUTRANS (buprenorphine) transdermal system to a clean, dry, non-irritated, and non-hairy area of the chest, back, flank, or upper arm. Initial dose: 5 mcg/h for opioid-naïve patients; titrate based on pain control and tolerability. Maximum dose: 20 mcg/h. Replace every 7 days. Rotate application sites.
100 mg orally twice daily.
