  • MetabollsmPantoprazole is extensively metabolized in the liver through the cytochrome P450 (CYP) system. The main metabolic pathway is demethylation, by CYP2C19, with subsequent sulfation; other metabolic pathways include oxidation by CYP3A4. There is no evidence that any of the pantoprazole metabolites have significant pharmacologic activity.
  • Half life1~2 h in good metabolisers (pantoprazole); 6 h in poor metabolisers (drug); 1.5 h (metabolites).
