Definition of MAO inhibitor
Medically reviewed by Min Clinic Staff | Updated: January 2026
MAO inhibitor: One of a family of medications (brand names: Aurorex, Nardil, Parnate) that act to limit the activity of monoamine oxydase (MAO) in the nervous system. MAOIs are prescribed to treat depression, anxiety, migraine, and selected other conditions in patients who are not responsive to other medications. They interact with many over-the-counter medications and some foods, so patients taking MAOIs must be educated about what to avoid and must follow a restricted diet.
