Video - Monoamine oxidase inhibitors

Monoamine oxidase inhibitors (MAOIs) are a class of medications used to treat depression, anxiety, and other mental health disorders. MAOIs work by blocking an enzyme called monoamine oxidase, which breaks down monoamine neurotransmitters, namely serotonin, norepinephrine, and dopamine, so they can be released again into the synapse. By blocking this enzyme, these chemicals are able to remain at higher levels in the brain, providing a beneficial effect on mood and behavior. Common side effects of MAOIs include drowsiness, dizziness, insomnia, dry mouth, and weight gain.
