I Once Was Prescribed A New Antidepressant Whose Name Was

I once was prescribed a new antidepressant whose name was something like "Lutava" or "Vatula" or something similar to it and it was VERY expensive. Do you know what the name is? It is supposed to attack two chemistries of your brain - instead of the traditional 1, and therefore, my doctor thinks it would work better than all other antidepressants that I tried which did NOT work for me at all.
