How do Nexium tablets work?

The active ingredient of Nexium tablets, Esomeprazole, is a selective proton pump inhibitor and it belongs to a class of drug known as Proton Pump Inhibitors (PPI) which are used in the treatment of acid reflux (GORD). Acid reflux is caused by two main factors; a build-up of excess stomach acid in addition to weakening of the lower sphincter muscles of the oesophagus. This muscle plays a vital role in the prevention and escape of stomach acid. Both these factors together result in stomach acid travelling up and into the oesophagus resulting in the symptoms of acid reflux.

The active ingredient of Nexium tablets, esomeprazole, works to treat symptoms of acid reflux by selectively acting on proton pumps at the surface of gastric parietal cells lining the stomach. These cells are involved in the production of gastric acid and its secretion into the stomach. Esomeprazole inhibits the final stage of this system resulting in reduced gastric acid production and secretion.

If you suffer from acid reflux or heartburn associated with excess stomach acid, you can buy Nexium 20mg tablets or generic esomeprazole tablets at Smart Chemist from just £12.99.
