Esomeprazole-d3 sodium

Esomeprazole-d3 sodium is a stable isotope-labeled standard of Esomeprazole sodium, used as an internal standard in biomedical research to improve the sensitivity and accuracy of mass spectrometry analysis. Esomeprazole sodium is a proton pump inhibitor that reduces gastric acid secretion by inhibiting the activity of the H?/K?-ATPase in gastric parietal cells, and is commonly used to treat gastroesophageal reflux disease, peptic ulcer, and other conditions. In in vitro studies, Esomeprazole sodium shows nanomolar to micromolar inhibitory activity against the H?/K?-ATPase in gastric parietal cells. In cell models, Esomeprazole sodium can reduce gastric acid secretion, and in animal models it is used to evaluate its efficacy in gastric acid-related diseases. The dose or concentration used in experiments typically depends on the experimental design and research objectives.
