Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nortriptyline, the active ingredient, is a tricyclic antidepressant that inhibits the reuptake of norepinephrine and serotonin at the presynaptic neuronal membrane, increasing their availability in the synaptic cleft.
Tricyclic antidepressant; inhibits reuptake of norepinephrine and serotonin at presynaptic neuronal membrane, increasing their concentration in the synaptic cleft.
25-150 mg orally per day, typically as a single daily dose at bedtime or in divided doses; start at 25 mg 1-3 times daily and titrate gradually. Maximum 150 mg/day.
Imipramine (PRAMINE) 75-150 mg orally once daily at bedtime, titrated from 25-50 mg, max 300 mg/day.

Mean terminal elimination half-life is 18-24 hours (range 13-40 hours) in adults; prolonged in elderly and hepatic impairment (up to 60 hours). Steady-state achieved in 4-5 days.
