Cytoprotective Barrier Agents

These medications protect the lining of the esophagus.

How Cytoprotective Barrier Agents Work

Cytoprotective barrier agents work by forming a material that adheres to the lining of your esophagus, providing a protective barrier against stomach acid and the irritation it can cause. In addition, if irritation or ulceration is already present in your esophagus, the barrier will coat the damage, allowing it to heal.
