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.
