"Essaven" is a brand name for the drug called "Esomeprazole," which is a proton pump inhibitor (PPI). It is primarily used to reduce the production of stomach acid, thereby treating conditions like gastroesophageal reflux disease (GERD), peptic ulcers, and other acid-related disorders. Esomeprazole works by blocking the enzyme system in the stomach that produces acid, thus providing relief from heartburn and other symptoms associated with excessive stomach acid. It is also used in combination with antibiotics to eradicate Helicobacter pylori, a bacterium that can cause ulcers.
