(R)-Lansoprazole, with the CAS number 138530-94-6, is a pharmaceutical compound belonging to the proton pump inhibitor class. It is an enantiomer of lansoprazole, specifically the right-handed (R) form. This compound is primarily used in the treatment of peptic ulcer disease, including duodenal ulcers and gastroesophageal reflux disease (GERD). By inhibiting the H+/K+-ATPase enzyme in gastric parietal cells, (R)-Lansoprazole effectively reduces gastric acid secretion, promoting healing of acid-related lesions.
