Chem mart Ranitidine is also used to treat a disease called gastrinoma and inflammation of the oesophagus caused by an autoimmune disease called scleroderma.


Ulcers in the stomach and duodenum are caused (or worsened) by too much acid in the stomach. Ranitidine is a drug that blocks acid production by special cells in the stomach.
