Esomeprazole is used to treat various conditions associated with high stomach acid levels.

Esomeprazole works by blocking a specific enzyme in the stomach lining, known as the proton pump. This action reduces the production of stomach acid.

By decreasing acid levels, it helps alleviate symptoms like heartburn and prevents damage to the esophagus.

This makes it effective for treating conditions where reducing stomach acid is beneficial.
