Why might an inhibitor of MAOB be less likely to cause a cheese reaction?

Question

Quizplus · Accepted Answer

The cheese reaction is caused by the interaction of tyramine, a compound found in certain foods like cheese, with MAO enzymes. MAO-A is the primary enzyme responsible for breaking down tyramine in the gut, while MAO-B plays a minor role. Inhibitors of MAO-A can lead to tyramine build-up in the bloodstream, causing the cheese reaction. However, MAO-B inhibitors are less likely to cause this because there are relatively few MAO-B enzymes in the gut compared to the CNS, where they are primarily located.
