MSH: A metabolite of AMITRIPTYLINE that is also used as an antidepressive agent. Nortriptyline is used in major depression, dysthymia, and atypical depressions.,CSP: tricyclic antidepressant of the dibenzocycloheptadiene class used to treat symptoms of depression and to relieve chronic, severe pain.,NCI: A tricyclic antidepressant agent used for short-term treatment of various forms of depression. Nortriptyline blocks the norepinephrine presynaptic receptors, thereby blocking the reuptake of this neurotransmitter and raising the concentration in the synaptic cleft in the CNS. Nortriptyline also binds to alpha-adrenergic, histaminergic and cholinergic receptors. Long-term treatment with nortriptyline produces a downregulation of adrenergic receptors due to the increased stimulation of these receptors.
