Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Clomipramine is a tricyclic antidepressant (TCA) that inhibits the reuptake of serotonin and norepinephrine, with a higher potency for serotonin reuptake inhibition. It also has anticholinergic, antihistaminergic, and alpha-adrenergic blocking properties.
Norepinephrine and serotonin reuptake inhibitor; also has anticholinergic and antihistaminergic activity.
Initial: 25 mg PO tid; increase gradually to 100-150 mg/day. Maximum: 250 mg/day. Maintenance: lowest effective dose.
10 mg orally twice daily (morning and afternoon) or 10 mg once daily at bedtime; may increase gradually to 60 mg/day in divided doses.

Terminal elimination half-life of clomipramine is approximately 21-26 hours; its active metabolite, desmethylclomipramine, has a half-life of approximately 36-42 hours. Steady-state is achieved within 7-14 days.
Terminal elimination half-life ranges 18–34 hours (mean ~25 hours); clinical steady-state achieved within 5–7 days.
Renal (primarily as conjugated metabolites, ~60-70% over 72 hours); fecal (biliary excretion of ~10-20%); <2% excreted unchanged in urine.
Primarily renal (approximately 70% as metabolites, <5% unchanged), with the remainder via fecal/biliary elimination.
