AVENTYL HYDROCHLORIDE vs PRESAMINE
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.
Predominantly inhibits serotonin reuptake in the presynaptic neuron, increasing serotonin availability in the synaptic cleft. Also inhibits norepinephrine reuptake to a lesser extent.
25 mg orally three times daily; may increase gradually to 150 mg/day in divided doses. Maximum dose 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 is approximately 19–24 hours; may be prolonged in elderly and patients with hepatic impairment.
21 hours (range 16-28 h) for imipramine; active metabolite desipramine ~24 h; clinically, steady-state reached in 5-7 days.
Primarily renal (approximately 70% as metabolites, <5% unchanged); biliary/fecal excretion accounts for ~30%.
