Monoamine oxidase inhibitors (MAOIs) are a class of medication used to treat depression. They were introduced in the 1950s as the first drugs for depression. Today, theyâre less popular than other depression medications, but some people benefit from their use.
Monoamine oxidase A. Monoamine oxidase A, also known as MAO-A, is an enzyme that in humans is encoded by the MAOA gene. Monoamine oxidase A is an isozyme of monoamine oxidase.It preferentially deaminates norepinephrine (noradrenaline), epinephrine (adrenaline), serotonin, and dopamine (which is equally deaminated by MAO-A and MAO-B).t is inhibited by clorgyline and befloxatone. Inhibition of both MAO-A and MAO-B using a monoamine oxidase inhibitor (MAO inhibitor) is used in the treatment of clinical depression, erectile dysfunction and anxiety.
