"With the possible exception of fluoxetine (multiple brands), the vast majority of antidepressants are ineffective, and some may even be unsafe, for use in children and teens with major depressive disorder (MDD), new research shows.
The mechanism of mood elevation by tricyclic antidepressants is at present unknown. Pamelor is not a monoamine oxidase inhibitor. It inhibits the activity of such diverse agents as histamine, 5-hydroxytryptamine, and acetylcholine. It increases the pressor effect of norepinephrine but blocks the pressor response of phenethylamine. Studies suggest that Pamelor interferes with the transport, release, and storage of catecholamines. Operant conditioning techniques in rats and pigeons suggest that Pamelor has a combination of stimulant and depressant properties.
