Mirtazapine Chemical Composition

Mirtazapine is a tetracyclic antidepressant that belongs to the class of noradrenergic and specific serotonergic antidepressants (NaSSAs). Its molecular formula is C17H19N3, and its molecular weight is approximately 265.35 g/mol.


The chemical structure of mirtazapine consists of a core fused tetracyclic ring system with a piperazine ring at one end. It contains carbon, hydrogen, and nitrogen atoms arranged in a specific configuration that gives mirtazapine its pharmacological properties.

Mirtazapine acts by blocking certain neurotransmitter receptors in the brain, specifically alpha-2 adrenergic autoreceptors and heteroreceptors. By doing so, it increases the release of norepinephrine and serotonin, which are key neurotransmitters involved in regulating mood and emotions.
