BUTRANS vs DSUVIA
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.
Selective, high-affinity agonist at the mu-opioid receptor, resulting in analgesia via activation of G-protein coupled inwardly rectifying potassium channels and inhibition of voltage-gated calcium channels in the central nervous system.
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.
30 mcg sublingual tablet as a single dose; may repeat once after 1 hour if needed. Maximum 2 doses per 24 hours.

Terminal half-life: 4-6 hours in healthy adults; prolonged to 12-18 hours in elderly or renal impairment
Terminal elimination half-life is approximately 23.4 hours (range 17–30 h), supporting once-daily dosing. Due to rapid redistribution, clinical effects may wane before elimination is complete.
Renal: 60-70% as unchanged drug and metabolites; biliary/fecal: 20-30%
Primarily renal elimination of metabolites; unchanged drug accounts for <1% of the dose. Fecal excretion is minimal. Total recovery: ~70% in urine, ~20% in feces.
