> Hmmm, Isn't Marplan Parnate minus the activating metabolite?
My current understanding, is that there is no such metabolite, but rather, the tranylcypromine (Parnate) itself has an intrinsic amphetamine-like action. That would seem to be the main reason why higher doses, beyond what is enough for complete MAO inhibition, is due to that intrinsic stimulant effect.
Selegiline, on the other hand, has amphetamine metabolites.
