Monoamines are connected to the pathophysiology of depression. Symptoms may occur because concentrations of neurotransmitters, such as norepinephrine and serotonin, are insufficient, leading to downstream changes. [10] [25] Medications for depression affect the transmission of serotonin, norepinephrine, and dopamine. [10]
Noradrenergic and specific serotonergic antidepressants (NaSSAs) are a class of psychiatric drugs used primarily as antidepressants.

KOR antagonists, in fact, are the focus of research into treatment for depression, anxiety, and substance use disorders. The idea is that these drugs seem to blunt the effects of the stress that ...
