3 classifications of antidepressants Monoamine Oxidase Inhibitors (MAOIs) Tricyclic Antidepressants or (TCAs) Selective Serotonin Reuptake Inhibitors (SSRIs)
Monoamine oxidase (MAO) Enzyme found in most body cells. The function of MAO is to break down norepinephrine and serotonin
Monoamine Oxidase Inhibitors (MAOIs) Drugs that DECREASE the amounts of NE and 5HT that are DESTROYED. Consequently levels of NE and 5HT in the brain will INCREASE.
A pt taking a monoamine oxidase inhibitors (MAOI)must Avoid foods that contain TYRAMINE.
