Prevacid

Prevacid®/Lansoprazole®/Lanton® (lansoprazole) is a proton pump inhibitor and acts in the stomach to decrease the production of stomach acid. Typically the stomach lining and duodenum (an area of the intestine directly after the stomach) are protected by a layer that resists acid attacks, but if this layer is damaged or acid production increases, a peptic ulcer can develop on the linings.
