Why do MAOIs interact with tyramine containing foods?

Medications called monoamine oxidase inhibitors (MAOIs) block monoamine oxidase, which is an enzyme that breaks down excess tyramine in the body. Blocking this enzyme helps relieve depression. If you take an MAOI and you eat high-tyramine foods, tyramine can quickly reach dangerous levels.

Is tyramine metabolized by Mao?

Tyramine is physiologically metabolized by monoamine oxidases (primarily MAO-A), FMO3, PNMT, DBH, and CYP2D6. Human monoamine oxidase enzymes metabolize tyramine into 4-hydroxyphenylacetaldehyde.

Which of the following MAO inhibitors is most likely to produce cheese reaction?

An acute attack of hypertension that can occur in a person taking a monoamine oxidase inhibitor (MAOI) drug who eats cheese, caused by an interaction of the MAOI with tyramine, formed in ripe cheese when bacteria provide an enzyme that reacts with the amino acid tyrosine in the cheese.

Is tyrosine and tyramine the same?

Tyrosine is the precursor to catecholamines and tyramine is a breakdown product of tyrosine. In the gut and during fermentation, tyrosine is decarboxylated to tyramine. Biogenic amines, including tyramine, are molecules that have allergenic properties and are often found in many fermented products.

What causes tyramine sensitivity?

Why You Should Avoid Tyramine The body relies on an enzyme known as monoamine oxidase to break tyramine down. Some people don’t have enough monoamine oxidase to process tyramine, resulting in high tyramine levels. Some medications also interfere with monoamine oxidase production, making tyramine consumption dangerous.
