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.

Adverse effects

Proton pump inhibitors may be associated with spontaneous bacterial peritonitis.[2] 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[3] or may not[4] increase adverse cardiac events when given to patients taking clopidogrel for coronary heart disease.
