Omeprazole sodium is widely used in the treatment of gastrointestinal disorders, particularly those related to excessive stomach acid production. It is commonly prescribed for conditions such as gastroesophageal reflux disease (GERD), where it helps to alleviate symptoms like heartburn and acid regurgitation. Additionally, it is effective in managing peptic ulcers, both gastric and duodenal, by reducing acid secretion and promoting healing. Omeprazole sodium is also utilized in the treatment of Zollinger-Ellison syndrome, a rare condition characterized by the overproduction of stomach acid. In combination with antibiotics, it plays a crucial role in eradicating Helicobacter pylori infections, which are a major cause of stomach ulcers. Its ability to inhibit the proton pump in the stomach lining makes it a key therapeutic agent in various acid-related disorders.
