Rantac 150 mg (Ranitidine 150 mg)

Ranitidine is used to treat and prevent ulcers in the stomach and intestine. It also treats diseases in which the stomach produces too much acid, such as Zollinger-Ellison syndrome. Rantac is also used to treat gastroesophageal reflux disease (GERD) and other conditions in which acid backs up from the stomach into the esophagus, causing heartburn.

How Rantac 150 mg works?

Rantac belongs to a group of medicines that reduce the amount of acid produced by the cells in the lining of the stomach. They are called ‘histamine H2-receptor antagonists’, but are commonly also called H2 blockers.

Ranitidine 150 is helpful in the treatment of conditions caused by too much acid being produced in the stomach. These conditions include stomach ulcers (gastric ulcers), ulcers of the upper part of the intestine (duodenal ulcers), acid reflux or heartburn (reflux oesophagitis), and indigestion. Rantac is also prescribed to treat ulceration of the stomach which has been caused by non-st***idal anti-inflammatory drugs (NSAIDs).
