Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nortriptyline, the active ingredient, inhibits the reuptake of norepinephrine and serotonin in the central nervous system, potentiating their effects. It also has anticholinergic and antihistaminergic properties.
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.
Adults: 25 mg orally 3 to 4 times daily, maximum 150 mg/day.
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.
