Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Predominantly inhibits serotonin reuptake in the presynaptic neuron, increasing serotonin availability in the synaptic cleft. Also inhibits norepinephrine reuptake to a lesser extent.
Selective histamine H1 receptor antagonist; promotes sleep by antagonizing central histaminergic neurotransmission.
100-300 mg/day orally in divided doses, typically starting at 75 mg/day and titrating upward. Maximum dose 300 mg/day.

21 hours (range 16-28 h) for imipramine; active metabolite desipramine ~24 h; clinically, steady-state reached in 5-7 days.
Terminal elimination half-life is approximately 10 hours (range 8-15 hours) in healthy adults; prolonged in elderly and hepatic impairment.
Primarily renal (70% as metabolites, <5% unchanged); biliary/fecal (30%).
Primarily renal (approximately 60% as unchanged drug and metabolites), with 30% fecal elimination.
