Both are quite similar, and that is no surprise, given that Notrtiptyline is Amitriptyline's major metabolite.
When comparing both, we can ascertain the following: Amitriptyline has somewhat more SERT blocking going on, so might be slightly more "serotonergic" than Nortriptyline, although I am not quite sure if clinically relevant. Both are equally strong NRIs and 5HT2 antagonists. Amitriptyline is a stronger ALPHA1 blocker compared to Nortriptyline, so might cause more postural hypotension. Amitrptyline is a stronger antihistamine than Nortriptyline, so might cause more sedation and appetite. Amitriptyline is a stronger anticholinergic than Nortriptyline, so will probably cause more side effects. (Although stronger sedative and anticholinergic properties might be welcome, depending on the condition)
What I am interested in: Who's been on both and how did they compare? (not only theoretically, but practically)
