Nortriptyline is an active metabolite of amitriptyline by demethylation in the liver. Chemically, it is a secondary amine dibenzocycloheptene and pharmacologically it is classed as a first-generation antidepressant. [36] Nortriptyline may also have a sleep-improving effect due to antagonism of the H 1 and 5-HT 2A receptors. [37]
Most are non-toxic at less than 5 mg/kg except for desipramine, nortriptyline, and trimipramine, which are generally non-toxic at less than 2.5 mg/kg. [5] [2] In small children one or two pills can be fatal. [6] An electrocardiogram (ECG) should be included in the assessment when there is concern of an overdose. [2]
ATC code N06 Psychoanaleptics is a therapeutic subgroup of the Anatomical Therapeutic Chemical Classification System, a system of alphanumeric codes developed by the World Health Organization (WHO) for the classification of drugs and other medical products.
For example, another study published in the International Journal of Neuropsychopharmacology in 2011 compared the effects of escitalopram and nortriptyline, a tricyclic antidepressant, on the body ...
Nortriptyline (Pamelor, Aventyl) Noxiptiline (Agedal, Elronon, Nogedal) Pipofezine (Azafen/Azaphen) Protriptyline (Vivactil) Trimipramine (Surmontil) Opipramol (Insidon), tianeptine (Stablon, Coaxil) and amineptine (discontinued; formerly Survector, Maneon) are chemically TCAs but are pharmacodynamically atypical, and are therefore grouped ...
The TCAs are used primarily in the clinical treatment of mood disorders such as major depressive disorder (MDD), dysthymia, and treatment-resistant variants. They are also used in the treatment of a number of other medical disorders, including cyclic vomiting syndrome (CVS) and anxiety disorders such as generalized anxiety disorder (GAD), social phobia (SP) also known as social anxiety ...
Nortriptyline reaches 10% higher level in the blood plasma than the parent drug amitriptyline and 40% greater area under the curve, and its action is an important part of the overall action of amitriptyline. [5] [9] Another active metabolite is (E)-10-hydroxynortriptyline, which is a norepinephrine uptake inhibitor four times weaker than ...
Other secondary amine TCAs include desipramine and nortriptyline. [ 26 ] [ 27 ] The chemical name of protriptyline is 3-(5 H -dibenzo[ a , d ][7]annulen-5-yl)- N -methylpropan-1-amine and its free base form has a chemical formula of C 19 H 21 N 1 with a molecular weight of 263.377 g/mol. [ 28 ] The drug is used commercially mostly as the ...
