Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nortriptyline, the active ingredient, inhibits the reuptake of norepinephrine and serotonin in the central nervous system, potentiating their effects. It also has anticholinergic and antihistaminergic properties.
Predominantly inhibits serotonin reuptake in the presynaptic neuron, increasing serotonin availability in the synaptic cleft. Also inhibits norepinephrine reuptake to a lesser extent.
Adults: 25 mg orally 3 to 4 times daily, maximum 150 mg/day.
100-300 mg/day orally in divided doses, typically starting at 75 mg/day and titrating upward. Maximum dose 300 mg/day.

Terminal elimination half-life: 19-24 hours; requires 4-6 days to reach steady state.
21 hours (range 16-28 h) for imipramine; active metabolite desipramine ~24 h; clinically, steady-state reached in 5-7 days.
Renal (30% as unchanged drug and metabolites); biliary/fecal (70% as metabolites)
Primarily renal (70% as metabolites, <5% unchanged); biliary/fecal (30%).
