Zantac

Zantac is a brand of ranitidine which is used to treat a number of conditions including acid reflux, also known as heartburn. Acid reflux is caused by hydrochloric acid from the stomach flowing up through the oesophagus when the muscular valve (the lower oesophageal sphincter) which normally prevents this stops working. The lining of the oesophagus is not protected against this acid in the same way the stomach is, therefore a painful burning sensation is experienced in the chest as a result. Zantac tablets treat this condition by reducing the amount of acid produced in the stomach to prevent any excess acid reaching the oesophagus and allowing it to heal.

How long does Zantac take to work?

Zantac can begin to relieve the symptoms of acid reflux after 30 minutes.

How long will Zantac subdue the symptoms of acid reflux for?

Each dose of Zantac will suppress stomach acid for around 12 hours.

What else can I do to prevent acid reflux?

Making a number of lifestyle changes can effectively control and minimise the occurrence of acid reflux. Losing weight if necessary, stopping smoking and making dietary changes such as removing food triggers and eating smaller meals could all reduce the likelihood of suffering from heartburn.
