Introduction
Esomeprazole is the (S) enantiomer of Omeprazole. Esomperazole is a Proton Pump Inhibitor (PPI) that binds to H+/K+-ATPase and inhibits the secretion of gastric acid from parietal cells into the lumen of the stomach. Esomeprazole’s commercial brand name, Nexium, is used to treat Gastro-esophageal Reflux Disease (GERD), peptic and gastric ulcers, and Zollinger-Ellison syndrome.[1]
Ulcers caused by the bacterium Helicobacter pylori can be treated using Esomeprazole in conjunction with proper antibiotics.[1] Gastric acid is released through the H+/K+-ATPase pump, which is the final step in acid release. [2] Esomeprazole is a specific, irreversible inhibitor of the pump. [2]
