Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Agonist at kappa-opioid receptors and antagonist at mu-opioid receptors; produces analgesia through spinal and supraspinal mechanisms.
30 mcg sublingual tablet as a single dose; may repeat once after 1 hour if needed. Maximum 2 doses per 24 hours.
50 mg orally every 3-4 hours as needed; maximum 600 mg/day. For severe pain, 30 mg intramuscularly or subcutaneously every 3-4 hours; maximum 360 mg/day parenterally.

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.
2-3 hours in adults; prolonged to 4-6 hours in hepatic impairment; clinical context: short half-life necessitates frequent dosing for chronic pain
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.
Renal: 60-70% as unchanged drug and metabolites (pentazocine and its glucuronide conjugate); biliary/fecal: 20-30%
