Why do MAO inhibitors cause hypertensive crisis?
In the presence of MAOIs, tyramine displaces norepinephrine from synaptic vesicles, leading to profound hypertension. When an indirect-acting sympathomimetic drug such as ephedrine is administered, an exaggerated BP increase can occur, especially in the first weeks of therapy with an MAOI.
How does MAOI cause hypertensive crisis?
