"Recently, amitriptyline has been demonstrated to act as an agonist of the TrkA and TrkB receptors.[26] It promotes the heterodimerization of these proteins in the absence of NGF and has potent neurotrophic activity both in-vivo and in-vitro in mouse models.[26][27] These are the same receptors BDNF activate, an endogenous neurotrophin with powerful antidepressant effects, and as such this property may contribute significantly to its therapeutic efficacy against depression. Amitriptyline also acts as FIASMA (functional inhibitor of acid sphingomyelinase)"
isnt this one of the best positive influences from antidepressant you know ? look at this ! some pretty good nootropic effect for sure ! was aiming for people's response who have tried it tho because thats the only way to know exactly how all this fit in actual regular usage.
