AVENTYL HYDROCHLORIDE vs JANIMINE
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.
Imipramine inhibits the reuptake of norepinephrine and serotonin at nerve terminals, potentiating their neurotransmission. It also has anticholinergic and antihistaminergic effects.
25 mg orally three times daily; may increase gradually to 150 mg/day in divided doses. Maximum dose 150 mg/day.
25-50 mg orally 2-4 times daily; maintenance 150 mg/day divided

Terminal elimination half-life is approximately 19–24 hours; may be prolonged in elderly and patients with hepatic impairment.
5-15 hours (terminal elimination half-life); clinical context: requires twice-daily dosing for steady state.
Primarily renal (approximately 70% as metabolites, <5% unchanged); biliary/fecal excretion accounts for ~30%.
Primarily renal (70-80% as metabolites, 5% unchanged); biliary/fecal (20-30% as metabolites).
