What is the major reason that monoamine oxidase inhibitors (MAOIs) are rarely used in clinical practice today?
They are under a scheduled drug classification.
They are ineffective in treating depression or anxiety disorders.
They can cause gastrointestinal (GI) bleeding and esophageal varices.
They may cause dangerous interactions with some foods and drugs.
The Correct Answer is D
A. While MAOIs may have some regulatory considerations, they are not classified under a scheduled drug classification like controlled substances.
B. MAOIs are effective in treating depression and anxiety disorders, which is not the reason for their limited use.
C. Although MAOIs can have some side effects, they are more notably associated with dietary and drug interactions rather than causing GI bleeding or esophageal varices.
D. MAOIs can cause dangerous interactions with foods that contain tyramine (like aged cheeses and fermented products) and certain medications, leading to hypertensive crises, making their use cautious and limiting in clinical practice.

Correct Answer is A
Explanation
A. Try not to swallow while the pill dissolves is correct because sublingual medications are designed to be absorbed directly into the bloodstream through the mucous membranes under the tongue, and swallowing may hinder this absorption.
B. Take a big drink of water and swallow the pill is incorrect because sublingual medications should not be swallowed with water as they need to dissolve under the tongue.
C. Swallow frequently to get the best benefit is incorrect, as this can interfere with the absorption of the medication.
D. Chew the pill so it will dissolve faster is incorrect since chewing may destroy the sublingual formulation, preventing it from working as intended.
