monoamine oxidase inhibitor

drug
Also known as: MAO inhibitor, MAOI

Quick Summary

Monoamine oxidase inhibitors (MAOIs) are a class of drugs used to treat depression. They work by inhibiting monoamine oxidase, an enzyme that breaks down neurotransmitters like serotonin and norepinephrine in the brain. By preventing the breakdown of these neurotransmitters, MAOIs allow them to accumulate, which is thought to help alleviate symptoms of depression.12

MAOIs were among the first antidepressants discovered in the 1950s. However, due to potential side effects and dangerous interactions with certain foods (like those containing tyramine) and other medications, they are often used when other antidepressants have not been effective.12
