Esomeprazole sodium

Esomeprazole sodium - the sodium salt of the s isomer of omeprazole, with gastric proton pump inhibitor activity. In the acidic compartment of parietal cells, esomeprazole is protonated and converted into the active achiral sulfenamide; the active sulfenamide forms one or more covalent disulfide bonds with the proton pump hydrogen potassium adenosine triphosphatase (h+/k+ atpase), thereby inhibiting its activity and the parietal cell secretion of h+ ions into the gastric lumen, the final step in gastric acid production. H+/k+ atpase is an integral membrane protein of the gastric parietal cell.
