> I noticed Remeron as a NE alpha2 antagonist and Trazodone as a NE alpha1 antagonist. I'm taking remeron for sleep but am finding it is causing increased agitation/frustration. Does anyone have an opinion as to trazadones likelihood of causing the same effect? I'm sure the NE is causing my agitation but I do not know the difference between the 2 NE actions of the two meds?
They work in quiet different ways...most alpha2s are inhibitors receptors which stop NE or other neurones from firing. And a few alpha2 postsynaptically, i only know of them in relationship to adhd: they help promote concentration. Alpha1s don't help with concentration they are afaik exclusivly postsynaptic and excitory. I haven't seen it written anywhere but i think the alpha1 blockade basically just causes sedation/calm in the brain. The mirt is a promiscous drug, its hard to know how its causing agitation, but needless to say mirt and traz are very different drugs...
