EC Pan Tablet 10's belongs to the class of drugs known as Proton pump inhibitor which reduces the amount of acid your stomach makes. It treats gastroesophageal reflexux disease (GERD), stomach ulcer, Zollinger Ellison syndrome (overproduction of acid due to pancreatic tumour), duodenal ulcer, gastric ulcer and Crohn’s Disease-associated Ulcers. EC Pan Tablet 10's helps in reducing the stomach acid by blocking the actions of an enzyme (H+/K+ ATPase or gastric proton pump). This proton pump lies in the cells of the stomach wall responsible for the release of gastric acid secretion damaging tissues in the food pipe, stomach and duodenum. EC Pan Tablet 10's prevents the release of stomach acid and relieves symptoms of food pipe lining inflammation (esophagitis) and gastroesophageal reflexux disease (GERD), or heartburn.
