Introduction to Nexium (Esomeprazole) 20mg
Nexium (Esomeprazole) 20mg is a prescription medicine used to treat acid-related conditions such as gastroesophageal reflux disease (GERD), acid reflux, and peptic ulcers. It works by reducing the amount of acid produced in the stomach, providing long-lasting relief and promoting healing of the digestive tract.
Exium 20mg is a local generic brand containing the same active ingredient Esomeprazole, offering similar therapeutic benefits under proper medical supervision.
It is classified under Prescription Medicines, Proton Pump Inhibitors (PPIs), Gastrointestinal Medicines, and Acid-Reducing Therapies.
What Is Nexium (Esomeprazole)?
Nexium is the brand name for Esomeprazole, an oral proton pump inhibitor widely used to control excessive stomach acid production.
Esomeprazole works by blocking the proton pumps (H⁺/K⁺-ATPase) in the stomach lining, significantly reducing acid secretion and allowing ulcers and esophageal irritation to heal.
Generic versions such as Exium 20mg contain the same active ingredient and may be used depending on physician guidance and availability.
