What is Sucralfate?
Sucralfate is a prescription medication used primarily to treat and prevent stomach and intestinal ulcers. It belongs to a class of drugs known as gastrointestinal protectants.
Instead of reducing stomach acid, Sucralfate works by forming a protective barrier over damaged areas in the digestive tract, allowing them to heal naturally.
How Sucralfate Works
Sucralfate reacts with stomach acid to create a thick, paste-like coating. This protective layer adheres to ulcer sites and shields them from further irritation caused by acid, bile, and digestive enzymes.
This action helps:
- Promote faster healing of ulcers
- Reduce pain and discomfort
- Prevent further damage to the stomach lining
Uses of Sucralfate
Sucralfate is commonly prescribed for:
1. Gastric and Duodenal Ulcers
Helps heal active ulcers and prevent recurrence.
2. Gastroesophageal Reflux Disease (GERD)
Used in some cases to protect the esophagus from acid irritation.
3. Gastritis
Reduces inflammation and protects the stomach lining.
4. Ulcer Prevention
Prescribed for patients at risk of developing ulcers, especially during long-term medication use.

Sucralfate vs Other Ulcer Medications
| Feature | Sucralfate | Proton Pump Inhibitors (PPIs) | Antacids |
|---|---|---|---|
| Mechanism | Protective barrier | Reduces acid production | Neutralizes acid |
| Action speed | Moderate | Slow but long-lasting | Fast |
| Systemic absorption | Minimal | Yes | Minimal |
