From:
$8.53
Omeprazole is a proton pump inhibitor (PPI) used to treat acid-related stomach and esophagus conditions, including gastroesophageal reflux disease (GERD), stomach ulcers, and erosive esophagitis. It works by blocking acid production in the stomach, helping relieve heartburn, promote healing of the esophagus, and prevent further irritation. Prilosec can also be used as part of a combination therapy to eradicate Helicobacter pylori infection.
