Which of the following is an MAOI?

• A. Phenelzine
• B. Diazepam
• C. Clonidine
• D. Albuterol

Answer: (A)

The main concept being tested is recognizing an MAOI, a drug class that inhibits the enzyme monoamine oxidase to raise levels of brain neurotransmitters such as serotonin, norepinephrine, and dopamine. Phenelzine is a classic monoamine oxidase inhibitor; it works by blocking monoamine oxidase, leading to increased monoamines and often helping antidepressant symptoms in patients who don’t respond to other treatments. The other drugs belong to different classes: diazepam is a benzodiazepine that enhances GABA activity for anxiety and seizures; clonidine is an alpha-2 adrenergic agonist used to lower blood pressure and other conditions; albuterol is a beta-2 agonist used as a bronchodilator for asthma and COPD. Therefore, phenelzine is the MAOI.
