3. How Do MAOIs Affect Tyramine Levels In The Body?

Monoamine oxidase inhibitors (MAOIs) work by blocking the activity of monoamine oxidase, an enzyme responsible for breaking down monoamines like tyramine, serotonin, norepinephrine, and dopamine. According to research published in the journal Neuropsychopharmacology, when MAOIs inhibit this enzyme, tyramine is not broken down as efficiently, leading to its accumulation in the body. This can trigger a rapid release of norepinephrine, a neurotransmitter that raises blood pressure, potentially leading to a hypertensive crisis.

3.1 The Process Of Tyramine Metabolism

Normally, when tyramine is ingested, it is metabolized in the gut and liver by monoamine oxidase. This process prevents tyramine from entering the bloodstream and causing significant effects on blood pressure. However, when MAO is inhibited, tyramine can bypass this breakdown and enter the circulation, leading to a surge in blood pressure.

3.2 Consequences Of Elevated Tyramine

Elevated tyramine levels can lead to several adverse effects, with the most serious being a hypertensive crisis. Symptoms of this condition include:

  • Severe headache
  • Nausea and vomiting
