pair of enantiomers
Rabeprazole (available as the brand-name drug Aciphex[1]) is a type of medicine called a proton pump inhibitor (PPI). It reduces the amount of acid the stomach makes.[2] It is widely used to treat heartburn, acid reflux and gastro-oesophageal reflux disease (GORD).[2] GORD is when someone keeps getting acid reflux. Rabeprazole is also taken to prevent and treat stomach ulcers.[2] Sometimes, it is also prescribed for a rare condition caused by a tumour in the pancreas or gut, called Zollinger-Ellison syndrome.[2]
