AVENTYL HYDROCHLORIDE vs TRIMIPRAMINE MALEATE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nortriptyline hydrochloride, the active ingredient in Aventyl Hydrochloride, is a tricyclic antidepressant that inhibits the reuptake of norepinephrine and serotonin at the presynaptic neuronal membrane, increasing their concentrations in the synaptic cleft. It also has antihistaminic, anticholinergic, and sedative properties.
Inhibits reuptake of norepinephrine and serotonin, with moderate anticholinergic, sedative, and antihistaminergic effects.
25 mg orally three times daily; may increase gradually to 150 mg/day in divided doses. Maximum dose 150 mg/day.
25-150 mg orally once daily at bedtime, starting at 25 mg and titrating up by 25 mg every 3-4 days.

Terminal elimination half-life is approximately 19–24 hours; may be prolonged in elderly and patients with hepatic impairment.
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 (approximately 70% as metabolites, <5% unchanged); biliary/fecal excretion accounts for ~30%.
Renal: ~70% as metabolites (unchanged <5%); fecal: ~30% via biliary excretion.
