What is Nexium and how does it work?
Nexium is known as the purple pill. It is a drug that is made by a company called AstraZeneca. Nexium treats gastroesophageal reflux or acid reflux disease aka Gerd. Nexium or esomeprazole magnesium is a proton pump inhibitor that goes into the stomach and reduces the acid in the stomach. The U.S. Food and Drug admin approved a generic version of the drug.
Acid reflux can be caused by a bad valve for the LES muscle. This muscle lies between the esophagus and the stomach and when food passes through it closes. Some people have a LES that doesn't close tight enough. Acid from the stomach then climbs up through the LES into the throat. It also can cause heartburn.
Acid reflux can be painful and harmful. It can cause a burning chest, a sour taste in ones mouth and make it difficult to swallow. Chest pain is another symptom.
Some people take antacids or H2 blockers or Nexium to relieve these symptoms.
