Answer: MDD, dysthymic, chronic
◉ Irreversible MAOA&B used to treat:
Answer: Depression, atypical
MDD, unresponsive to other antidepressants
◉ Irreversible MAO-B used to treat:
Answer: MDD in adults
◉ What is the treatment for MAOI induced orthostatic hypotension?
Answer: •Avoidance of caffeine, intake of 2L of fluid/day, addition of

Management: a-adrenergic antagonists such as phentolamine
(regitine) or chlorpromazine (thorazine) they will lower BP w/in 5
minutes. IV furosemide (Lasix) to reduce fluid load, and B-
