Desipramine is a metabolite of imipramine, as is nortriptyline of amitriptyline; they are both the secondary amine versions of their tertiary amine parents. Both tricyclics and SSRIs are metabolized by the CYP-450 enzyme system, with the 2D6 enzyme being a particularly important one in the metabolism of these drugs. I do not have specific data on the hepatotoxicity of tricyclics, but my understanding is that it is not necessarily any higher than other antidepressants. The psychotropic drugs I'm aware of that do have a higher incidence of hepatotoxicity are Serzone, Nardil, and pemoline. Even if you do have a liver issue, you may still be able to take these drugs as long as liver function is monitored during therapy, but I am not an MD.Stattera is a non-tricyclic that has psychopharmacologic effects very similar to that of desipramine. Both of these drugs are norepinephrine selective reuptake inhibitors, as is nortriptyline, for that matter. However, nortriptyline is dirtier than either desipramine or Strattera, a relatively strong histamine blockade probably being its most notable non-therapeutic effect.
