Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nortriptyline is a tricyclic antidepressant that inhibits the reuptake of norepinephrine and serotonin at the presynaptic neuronal membrane, increasing their concentrations in the synaptic cleft. It also has anticholinergic, antihistaminic, and alpha-adrenergic blocking properties.
Norepinephrine and serotonin reuptake inhibitor; also has anticholinergic and antihistaminergic activity.
25 mg orally three times daily or 75 mg orally once daily at bedtime; initial dose 25 mg at bedtime, titrate up to 75-150 mg/day.
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.
