Controlling Heartburn and Acid Reflux
Indigestion and Acid Reflux: The most common applications of Rantac 150 help treat heartburn. Heartburn occurs when stomach acid flows upward into the oesophagus. Acid reflux is a common problem in which stomach acid keeps flowing back to the oesophagus, irritating it.
Managing Gastric Ulcers
Rantac 150 is also used to treat and prevent gastric ulcers. Ulcers are sores that develop in the stomach, small intestine, or oesophagus and are generally caused by a high amount of gastric acid.
Management of Zollinger-Ellison Syndrome
A disorder known as Zollinger-Ellison Syndrome is one in which one or more tumours form in the pancreas, and sometimes within the upper part of your small intestine, eventually triggering acid-producing cells to make too much gastric juice. Rantac 150 is used to treat. It functions by reducing the quantity of acid produced in the stomach.
