Description: Ilaprazole, also known as IY81149 is an Anti-ulcer agent. Ilaprazole is a proton pump inhibitor (PPI) used in the treatment of dyspepsia, peptic ulcer disease (PUD), gastroesophageal reflux disease (GORD/GERD) and duodenal ulcer. Clinical studies show that ilaprazole is at least as potent a PPI as omeprazole when taken in equivalent doses. Studies also showed that ilaprazole significantly prevented the development of reflux oesophagitis.
