Esomeprazole (Magnesium trihydrate)

Esomeprazole Magnesium is the magnesium salt of esomeprazole, 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 sulphenamide; the active sulphenamide 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.

How to use

In Vitro:

Esomeprazole magnesium trihydrate is develped from Esomeprazole strontium tetrahydrate (EST). EST contains esomeprazole, the S-enantiomer of omeprazole a salt-exchanged version of Esomeprazole magnesium trihydrate.

In Vivo:

Esomeprazole magnesium (0.5-50 mg/kg; oral gavage; daily; for 10 days; A/J mice) treatment increases gastric total antioxidant capacity and Cu/Zn-superoxide dismutase activity.
