Mechanism of action

Esomeprazole is the active S-enantiomer of omeprazole and works by inhibiting the final step of gastric acid production. The enteric coating allows the tablet to bypass the acidic stomach environment and dissolve in the small intestine, where the drug is absorbed and then transported to parietal cells to exert its acid-suppressing effect. This sustained acid suppression promotes healing of acid-related lesions and provides symptom relief.
