About
Mirtazapine is an antidepressant belonging to the tetracyclic antidepressant class, primarily used to treat major depressive disorder. It works by enhancing noradrenergic and serotonergic neurotransmission in the brain, specifically by blocking alpha2-adrenergic autoreceptors and heteroreceptors, and by antagonizing 5-HT2 and 5-HT3 serotonin receptors. This unique mechanism of action leads to increased release of norepinephrine and serotonin, improving mood and reducing symptoms of depression. Mirtazapine is also known for its sedative and appetite-stimulating effects, which can be beneficial for patients experiencing insomnia and weight loss associated with depression, contributing to overall recovery.
