Duloxetine and Mirtazapine: Mechanism of Action

Duloxetine and Mirtazapine are two distinct antidepressants that work through different mechanisms of action.


Duloxetine is a selective serotonin and norepinephrine reuptake inhibitor (SNRI). It acts by blocking the reuptake of serotonin and norepinephrine in the central nervous system, thereby increasing the levels of these neurotransmitters.


Mirtazapine, on the other hand, is a noradrenergic and specific serotonergic antidepressant (NaSSA). It works by enhancing the release of norepinephrine and serotonin in the brain and also by blocking certain serotonin receptors.

By targeting different neurotransmitter systems, Duloxetine and Mirtazapine offer a unique approach to treating depression and other mood disorders.
