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.
Selective serotonin reuptake inhibitor (SSRI); potentiates serotonergic activity by blocking serotonin reuptake into presynaptic neurons.
30 mcg sublingual tablet as a single dose; may repeat once after 1 hour if needed. Maximum 2 doses per 24 hours.
25 mg orally twice daily

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.
Terminal elimination half-life: 6-8 hours in adults; may be prolonged (up to 12 hours) in elderly or patients with renal impairment (CrCl <30 mL/min).
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.
Primarily renal excretion of unchanged drug (70-80%); fecal elimination accounts for 15-20% via biliary excretion; less than 5% as metabolites.
