Omeprazole

Omeprazole is a medication primarily used to treat conditions related to excessive stomach acid. Here are its main uses:

1. **Gastroesophageal Reflux Disease (GERD)**: Omeprazole is commonly prescribed to alleviate symptoms of GERD, where stomach acid frequently flows back into the esophagus, causing heartburn and irritation.

2. **Peptic Ulcers**: It helps heal and prevent the recurrence of peptic ulcers (sores on the lining of the stomach or duodenum) by reducing stomach acid production.

3. **Zollinger-Ellison Syndrome**: This is a rare condition in which the stomach produces too much acid. Omeprazole can be used to manage this excess acid production.

4. **Erosive Esophagitis**: Caused by inflammation and damage to the esophagus due to acid reflux, omeprazole can help heal the esophagus.

5. **Helicobacter Pylori Eradication**: Omeprazole is often part of a combination therapy to eradicate H. pylori infection, which can lead to ulcers.

### Dosage and Administration
Omeprazole is usually taken orally, often in the form of delayed-release capsules or tablets. It is generally recommended to take it before meals for optimal effectiveness.
