Emanera is a medication containing Esomeprazole, a proton pump inhibitor that works by reducing the production of stomach acid. Esomeprazole inhibits the enzyme H+/K+ ATPase in the gastric parietal cells, leading to a decrease in acid secretion. This medication is commonly prescribed for the treatment of gastroesophageal reflux disease (GERD), erosive esophagitis, and peptic ulcers. Emanera helps relieve symptoms such as heartburn, acid regurgitation, and indigestion. It also aids in healing and preventing damage to the esophagus caused by stomach acid. Emanera is effective in managing excessive stomach acid production and promoting healing of the gastrointestinal tract.
