Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Amoxapine, a dibenzoxazepine tricyclic antidepressant, primarily inhibits the reuptake of norepinephrine and serotonin. Its metabolite, 7-hydroxyamoxapine, exhibits dopamine D2 receptor antagonism, contributing to its antipsychotic effects.
Imipramine inhibits the reuptake of norepinephrine and serotonin at nerve terminals, potentiating their neurotransmission. It also has anticholinergic and antihistaminergic effects.
50 mg orally three times daily, increased gradually to 100-200 mg/day in divided doses. Max 300 mg/day.

Terminal elimination half-life is approximately 24-30 hours. Clinical context: Steady-state is reached within 5-7 days; the half-life supports once-daily dosing in most patients.
5-15 hours (terminal elimination half-life); clinical context: requires twice-daily dosing for steady state.
Renal (approximately 50% as unchanged drug and metabolites), biliary/fecal (30-40%), with the remainder as other metabolites; <10% excreted unchanged in urine.
Primarily renal (70-80% as metabolites, 5% unchanged); biliary/fecal (20-30% as metabolites).
