Amitriptyline and
nortriptyline are in the same class—both are
tricyclic antidepressants—but they are not the same medication. Amitriptyline is a first-generation tricyclic, while nortriptyline is second-generation, and as such, generally has a lower incidence of side effects than amitriptyline, just as pregabalin generally has a lower incidence of side effects than gabapentin.
