Ranitidine is a prescription-only medicine used in the treatment of excessive acid in the stomach. It is also used to treat other conditions in the stomach, intestine, and oesophagus.
Acid reflux, also known as indigestion, heartburn or gastroesophageal reflux disease is a very common condition which is characterised by a burning or gnawing pain, usually felt around the middle of the lower chest area. It's caused by acid escaping up into the esophagus from your stomach. Doctors would consider you to have acid reflux if you feel the symptoms of heartburn more than twice in a week.
While the lining of your stomach is adapted to protect it from the strong stomach acid, your esophagus is not. If the muscle which prevents acid leaking up from the stomach into your esophagus fails, the acid can irritate it causing pain, which is often felt just after having a meal.
There are a number of over the counter prescription medications which can help with the discomfort of acid reflux by reducing the amount of acid made in the stomach, such as Esomeprazole, Lansoprazole and Omeprazole, and you can find them here at UK Meds.

It is also used to treat certain stomach and throat problems such as erosive esophagitis, gastroesophageal reflux disease or GERD, and Zollinger-Ellison syndrome.

It belongs to a class of drugs known as H2 blockers.
Ranitidine is a histamine-2 blocker. It works by decreasing the amount of acid produced in the stomach. Histamine is a chemical in the stomach that stimulates the production of acid. H-2 blockers like it inhibit the histamine on the stomach cells, which results in the reduction of acid produced in the stomach. Excessive acid can damage the stomach, oesophagus, and duodenum, leading to ulceration and inflammation. Reducing the amount of acid produced in the stomach helps prevent inflammation and ulcers caused by excessive acid.
Ranitidine is also used in the treatment of other throat and stomach problems such as gastroesophageal reflux disease, erosive esophagitis, and Zollinger-Ellison syndrome.
