Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Norpramin (desipramine) is a tricyclic antidepressant (TCA) that primarily inhibits the reuptake of norepinephrine, and to a lesser extent serotonin, at the presynaptic neuronal membrane, thereby increasing their concentrations in the synaptic cleft. It also has anticholinergic, antihistaminergic, and alpha1-adrenergic blocking properties.

25 mg orally three times daily; may increase gradually to 150 mg/day in divided doses. Maximum 200 mg/day.
150-300 mg oral in divided doses per day; 75-150 mg IM in divided doses per day

Terminal half-life: 18-34 hours (mean ~27 hours); clinical context: supports once-daily dosing, but steady-state requires 5-7 days.
Terminal elimination half-life is 14–21 hours. Steady-state is reached within 5–7 days. The half-life is prolonged in elderly and patients with hepatic impairment.
Primarily renal (70%) as metabolites and unchanged drug; biliary/fecal (30%) as metabolites.
Primarily renal (70%), with 30% as unchanged drug; remainder as glucuronide and sulfate conjugates. Biliary/fecal excretion accounts for <5%.
