Nortriptyline

Pronunciation

Definition 1

A drug used to treat depression. It may also be used to treat panic or anxiety disorders and certain types of pain, and to help people quit smoking. Nortriptyline increases the levels of norepinephrine and other natural chemicals in the brain. This helps improve mood and may reduce a person’s craving for nicotine. It is a type of tricyclic antidepressant. Also called Aventyl and Pamelor. (NCI Dictionary)

Definition 2

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. (NCI Thesaurus)
