Hi Kelley. Sorry to sound a bit dumb but do you mean they are interchangeable in the sense that **10mg amitriptyline **has the same potency as 10mg nortriptyline?
yes…they are basically the same…nort is the metabolized version of ami. Nort supposedly has less side effects of drowsiness and dry mouth (the anticholinergic stuff)…ami more sedating…Imipramine is in the middle…they are all tricyclics because of the molecular structure in a 3 ring shape, but not because they all hit the 3 neurotransmitters (sero, dopamine and Norepinephrine)…just sayin…
