Antacid drug that typically causes diarrhea?
**Core Concept**
Antacids are a class of medications used to neutralize stomach acid and provide quick relief from heartburn and acid reflux. However, some antacids can have side effects such as diarrhea due to their high potassium content or osmotic effects.
**Why the Correct Answer is Right**
The correct answer is associated with the antacid **Milk of Magnesia** (Magnesium Hydroxide). This medication works by neutralizing stomach acid and has a high osmotic effect, which can draw water into the intestines and cause diarrhea. Additionally, magnesium can also have a laxative effect, contributing to its potential to cause diarrhea.
**Why Each Wrong Option is Incorrect**
* **Option A:** Aluminum Hydroxide is another common antacid that is less likely to cause diarrhea compared to Magnesium Hydroxide.
* **Option B:** Calcium Carbonate is also an antacid that is generally well-tolerated and less likely to cause diarrhea.
* **Option D:** Sodium Bicarbonate is a mild antacid that is less likely to cause diarrhea and is often used in combination with other medications.
**Clinical Pearl / High-Yield Fact**
It's essential to note that antacids can have varying side effects, and patients with underlying conditions such as kidney disease or heart failure may need to be cautious when using these medications.
**Correct Answer:** C.
