Nexium（Cat No.:A000788）, containing the active ingredient esomeprazole magnesium, is a proton pump inhibitor (PPI) used primarily to treat conditions involving excessive stomach acid. Such conditions include gastroesophageal reflux disease (GERD), Zollinger-Ellison syndrome, and peptic ulcers. Esomeprazole magnesium works by irreversibly blocking the hydrogen-potassium ATPase enzyme system of the stomach’s parietal cells, significantly reducing the production of gastric acid. This action allows for the healing of damaged esophageal tissues and relief from symptoms of heartburn and acid reflux.
