what type of medicine is prilosec
A: Prilosec (omeprazole) belongs to a class of drugs called proton pump inhibitors (PPIs). PPIs decrease or block the production of stomach acid. Prilosec is used to treat the symptoms of gastroesophageal reflux disease (GERD), to promote healing of erosive esophagitis, and to treat or prevent ulcers.ERD happens when acid from the stomach flows backward into the esophagus (the tube between the throat and the stomach). It can cause heartburn and injure the esophagus. Prilosec is also used to treat erosive esophagitis and Zollinger-Ellison syndrome (a condition in which the stomach produces too much acid).
