Lansoprazole (Prevacid) is an antiulcerative drug used for the treatment of duodenal and gastric ulcers, reflux oesophagitis, and Zollinger-Ellison syndrome. During the bulk synthesis of lansoprazole, we have observed five impurities: lansoprazole N-oxide, lansoprazole sulfone N-oxide, lansoprazole sulfide, lansoprazole sulfone and N-aralkyl lansoprazole. The present work describes the synthesis and characterization of these impurities.
