BELBUCA vs DALGAN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Partial mu-opioid receptor agonist; produces analgesia by binding to mu-opioid receptors in the CNS, with ceiling effect on respiratory depression.
Dalgan (generic: dezocine) is a mixed opioid agonist-antagonist that acts as a partial agonist at mu-opioid receptors and a full agonist at kappa-opioid receptors, producing analgesia through modulation of pain signaling in the central nervous system. It also exhibits antagonist activity at mu receptors at higher doses, limiting its abuse potential and respiratory depression compared to full agonists.
Apply one buccal film to inner cheek every 12 hours. Initiate at 75 mcg once daily or every 12 hours for opioid-experienced patients; titrate in increments of 75-150 mcg every 4 days. Maximum dose: 900 mcg every 12 hours.
Oral: 50-100 mg every 6-8 hours; maximum 400 mg/day. IV: 25-50 mg every 6 hours; maximum 200 mg/day.

Terminal elimination half-life of buprenorphine is approximately 24-42 hours, allowing for twice-weekly dosing of BELBUCA.
Terminal half-life: 2–3 hours; clinically may be prolonged in renal impairment.
Primarily renal (70-80% as metabolites, ~15% as unchanged buprenorphine); biliary/fecal excretion accounts for ~10-20%.
Renal: ~90% as unchanged drug and glucuronide conjugates; biliary/fecal: ~10%.
