Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibits reuptake of serotonin and norepinephrine, leading to increased concentrations at synaptic cleft; also blocks histamine H1, alpha-1 adrenergic, and muscarinic cholinergic receptors.
Imipramine inhibits the reuptake of norepinephrine and serotonin at nerve terminals, potentiating their neurotransmission. It also has anticholinergic and antihistaminergic effects.
Oral: 25-150 mg daily in divided doses or as a single bedtime dose; maximum 300 mg/day.
25-50 mg orally 2-4 times daily; maintenance 150 mg/day divided

Terminal elimination half-life is 15-35 hours (range 9-46 hours); clinical context: steady-state concentrations achieved within 7-10 days; may be prolonged in elderly, hepatic impairment, or CYP2D6 poor metabolizers.
5-15 hours (terminal elimination half-life); clinical context: requires twice-daily dosing for steady state.
Primarily renal (approximately 30-50% as unchanged drug and metabolites, mainly glucuronide conjugates and hydroxylated metabolites). Fecal excretion accounts for <5%. Enterohepatic recirculation may occur.
Primarily renal (70-80% as metabolites, 5% unchanged); biliary/fecal (20-30% as metabolites).
