Used primarily in the treatment of gastrointestinal disorders, it is a proton pump inhibitor (PPI) that effectively reduces stomach acid production. It is particularly beneficial for managing conditions like gastric ulcers, duodenal ulcers, and gastroesophageal reflux disease (GERD). Additionally, it is employed in combination with antibiotics for eradicating Helicobacter pylori infections, which are linked to peptic ulcer disease. Its long-lasting action provides sustained acid suppression, making it suitable for patients requiring prolonged therapy. It is also being studied for potential applications in preventing stress-related mucosal damage in critically ill patients.
