Product Overview
Effective and established medication for the treatment of acid reflux.\n20mg tablets.
Description
Esomeprazole Gastro-Resistant Capsules are a prescription-only medicine used to reduce excess stomach acid. Esomeprazole belongs to a group of medicines known as proton pump inhibitors (PPIs), which work by decreasing the amount of acid produced in the stomach.
This treatment is commonly prescribed for conditions caused by excess stomach acid, including gastro-oesophageal reflux disease (GERD), heartburn, and stomach or duodenal ulcers. It may also be used alongside antibiotics to treat ulcers caused by Helicobacter pylori (H. pylori), to prevent ulcers linked to long-term NSAID use, or to manage rare conditions such as Zollinger-Ellison syndrome.
Suitable for adults and adolescents aged 12 years and over, Esomeprazole capsules are gastro-resistant to help protect the medicine from stomach acid and ensure it works effectively.
