Monoamine Oxidase Inhibitors (MAOIs) are a class of medications primarily used to treat depression. They work by inhibiting the activity of the enzyme monoamine oxidase, which breaks down neurotransmitters such as serotonin, norepinephrine, and dopamine. By preventing this breakdown, MAOIs can increase the levels of these neurotransmitters in the brain, thereby alleviating symptoms of depression.
