Study Notes

Antacids Overview

Antacids neutralize hydrochloric acid (HCl) in the stomach, effective against hyperacidity and related gastrointestinal disorders.
Commonly used for conditions like peptic ulcer disease, gastroesophageal reflux disease (GERD), and dyspepsia.

Administration Guidelines

Antacids should be taken at least one to two hours apart from other medications to avoid absorption interference.

Mechanism of Action

Antacids increase stomach pH, promoting early secretion instead of further intestinal absorption, particularly when using coated tablets or granules.

Side Effects

Aluminum-containing antacids may cause constipation.
Magnesium-based antacids can lead to osmotic diarrhea and are advantageous for those with mild constipation.
Sodium bicarbonate-containing antacids should be avoided in patients requiring sodium restriction, such as those with congestive heart failure (CHF) and hypertension.

Combination Therapies

Other agents that may be combined with antacids include:
- Simethicone: A defoaming agent that reduces excess gas in the stomach.
- Alginates: Form a gel or foam that prevents reflux and protects the esophageal mucosa from acid.
These combination products may be available as chewable tablets or suspensions.
