Pharmaceutical Information
Drug Name Omeprazole
Drug ID BADD_D01614
Description Originally approved by the FDA in 1989, omeprazole is a _proton-pump inhibitor_, used to treat gastric acid-related disorders. These disorders may include gastroesophageal reflux disease (GERD), peptic ulcer disease, and other diseases characterized by the oversecretion of gastric acid. This drug was the first clinical useful drug in its class, and its approval was followed by the formulation of many other proton pump inhibitor drugs [A174232]. Omeprazole is generally effective and well-tolerated, promoting its popular use in children and adults [FDA label].
Indications and Usage Omeprazole, according to the FDA label [FDA label] is a proton pump inhibitor (PPI) used for the following purposes: • Treatment of active duodenal ulcer in adults • Eradication of Helicobacter pylori to reduce the risk of duodenal ulcer recurrence in adults • Treatment of active benign gastric ulcer in adults • Treatment of symptomatic gastroesophageal reflux disease (GERD) in patients 1 year of age and older • Treatment of erosive esophagitis (EE) due to acid-mediated GERD in patients 1 month of age and older • Maintenance of healing of EE due to acid-mediated GERD in patients 1 year of age and older • Pathologic hypersecretory conditions in adults
