Monoamine oxidase inhibitors are an extremely potent class of antidepressants that treat depression by preventing the breakdown of serotonin, dopamine, and norepinephrine in the brain, increasing their availability. These medications are not used often because of their potential for drug interactions that can lead to problems with blood pressure as well as the need to avoid foods that contain the amino acid tyramine.
