Abstract

Twice‐daily dosing of proton pump inhibitors (PPIs) is used to treat Helicobacter pylori or acid‐related diseases, such as gastro‐oesophageal reflux disease (GERD) refractory to standard dose of a PPI. Genetic polymorphisms of CYP2C19 are involved to different extents in the metabolism of four kinds of PPIs (omeprazole, lansoprazole, rabeprazole and esomeprazole) available in Japan.
