PERTOFRANE vs SURMONTIL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Tricyclic antidepressant that inhibits the reuptake of norepinephrine and serotonin at the presynaptic neuronal membrane, increasing their concentrations in the synaptic cleft.
Tricyclic antidepressant that inhibits the reuptake of norepinephrine and serotonin, with anticholinergic, antihistaminergic, and alpha-adrenergic blocking properties.
150-300 mg oral in divided doses per day; 75-150 mg IM in divided doses per day
50-75 mg/day orally in divided doses, increase gradually to 150-300 mg/day. Maximum 300 mg/day. Single bedtime dose may be used for maintenance (50-150 mg).

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.
11-27 hours (mean approximately 20 hours) for the parent drug; the active metabolite desmethyltrimipramine has a half-life of 15-30 hours. Steady-state is achieved within 5-7 days.
Primarily renal (70%), with 30% as unchanged drug; remainder as glucuronide and sulfate conjugates. Biliary/fecal excretion accounts for <5%.
Renal excretion of metabolites accounts for approximately 70-80% of elimination, with about 20-30% excreted in feces via biliary elimination. Unchanged drug in urine is less than 5%.
