Is mirtazapine a MOI

No, mirtazapine is not a monoamine oxidase inhibitor (MAOI). It is classified as a noradrenergic and specific serotonergic antidepressant (NaSSA). Mirtazapine works by enhancing the release of norepinephrine and serotonin, but it does not inhibit the monoamine oxidase enzyme, which is the mechanism of action for MAOIs.
