Zantac is a medicine which is used in a number of conditions. Zantac tablets, effervescent tablets, syrup and injection all contain the active ingredient ranitidine, which is a type of medicine called an H2 receptor antagonist. It is made by GlaxoSmithKline UK.
Since ranitidine reduces the amount of acid in your stomach, Zantac tablets are used:
> To heal and prevent ulcers in the stomach or, the part it empties into, the duodenum
> To clear up infection with the germ Helicobacter pylori when used with antibiotics
> To prevent ulcers from bleeding
> To heal and prevent problems caused by acid in the gullet (oesophagus) or too much acid in the stomach, which can cause * pain or discomfort sometimes known as “indigestion”, “dyspepsia” or “heartburn”
> To prevent ulcers, which can be a side effect of some medicines used to treat arthritis
> Before surgical operations, to prevent acid coming up from the stomach during the anaesthetic.
