Mechanism of action

Esomeprazole is the active S-enantiomer of omeprazole. It irreversibly inhibits the proton pump (H+/K+-ATPase) on the secretory surface of gastric parietal cells, reducing both basal and stimulated gastric acid production. This mechanism provides rapid and sustained acid suppression, making it effective for treating acid-related gastrointestinal disorders.
