What is the desirable effect of simethicone for relief of gastrointestinal distress?

• A. It absorbs excess HCl.
• B. It reduces gas distension.
• C. It stimulates peristalsis.
• D. It prevents diarrhea.

Answer: (B)

Simethicone works by decreasing the surface tension of gas bubbles in the intestines, causing scattered gas to coalesce into larger bubbles that are easier to pass or reabsorb. This reduces gas distension and the accompanying bloating and discomfort. It does not neutralize stomach acid, stimulate intestinal movement, or prevent diarrhea, which is why its desirable effect is relief of gas distension.
