Lansoprazole Uses

Lansoprazole is used to treat conditions in which there is too much acid secretion in the stomach. It is used to relieve symptoms of gastroesophageal reflux disease (GERD) and ulcers in the stomach and duodenum. It is administered concomitantly with two other medicines as part of triple therapy for Helicobacter pylori (H. pylori) infections. Lansoprazole is also prescribed to people with certain other conditions in which there is excess stomach acid production, such as Zollinger-Ellison syndrome.

There may be other uses of lansoprazole. Your healthcare professionals or pharmacist can give you further lansoprazole drug information.

Lansoprazole Mechanism of Action
