inhibitor for treating various types of gastrointestinal ulcers, dyspepsia
gastroesophageal reflux disease (GORD/GERD) and Zollinger-Ellison syndrome.

markedly inhibits basal and stimulated gastric acid secretion. Thus it is
antisecretory drug which is very effective for rapidly healing peptic ulcers
& erosive oesophagitis & for reducing gastric acid hyper-secretion
in patients with Zollinger-Ellison syndrome.
