Definitions for "Esomeprazole"
Esomeprazole (IPA: ) is a proton pump inhibitor (brand names Nexium®; Lucen®; Esopral® and Axagon® in Italy) developed and marketed by Astra Zeneca which is used in the treatment of dyspepsia, peptic ulcer disease (PUD), gastroesophageal reflux disease (GORD/GERD) and Zollinger-Ellison syndrome. Esomeprazole is the S-enantiomer of omeprazole (marketed as Losec/Prilosec), and AstraZeneca claims improved efficacy of this single enantiomer product over the racemic mixture of omeprazole. However, this alleged greater efficacy has been disputed, with many claiming it offers no benefit from its older form. (see below).
