PRESAMINE vs TRIMIPRAMINE MALEATE
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.
Inhibits reuptake of norepinephrine and serotonin, with moderate anticholinergic, sedative, and antihistaminergic effects.
100-300 mg/day orally in divided doses, typically starting at 75 mg/day and titrating upward. Maximum dose 300 mg/day.
25-150 mg orally once daily at bedtime, starting at 25 mg and titrating up by 25 mg every 3-4 days.

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: 22–32 hours (mean 24 hours); in elderly or hepatic impairment, may extend to 40–50 hours requiring dose adjustment.
Primarily renal (70% as metabolites, <5% unchanged); biliary/fecal (30%).
Renal: ~70% as metabolites (unchanged <5%); fecal: ~30% via biliary excretion.
