In medicine, proton pump inhibitors (PPI) are medications that "inhibit H(+)-K(+)-exchanging atpase. They are used as anti-ulcer agents and sometimes in place of histamine H2 antagonists for gastroesophageal reflux."[1] They are also used as part of curative [therapy for Helicobacter pylori, in combination with antibiotics.
Metabolism
Proton pump inhibitors are metabolized by the CYP2C19 isoenzyme of cytochrome P-450. This may be less true for pantoprazole and esomeprazole.[2]
Adverse effects
Proton pump inhibitors may be associated with spontaneous bacterial peritonitis.[3] These drugs may also be associated with pneumonia, Clostridium difficile diarrhea, and fractures.
Proton pump inhibitors, which are metabolized by the CYP2C19 isoenzyme of cytochrome P-450, may[4] or may not[5] increase adverse cardiac events when given to patients taking clopidogrel for coronary heart disease.
