WebMost PPIs are metabolized by CYP2C19 and their pharmacokinetics are affected by CYP2C19 phenotype (Furuta et al., 1998). Both CYP2C19 IMs and PMs have higher PPI plasma concentrations compared to NMs, and consequently, the success rate of Helicobacter pylori eradication therapy depends on CYP2C19 genotype (Zhao et al., 2008). WebDrugs can be metabolized by oxidation, reduction, hydrolysis, hydration, conjugation, condensation, or isomerization; whatever the process, the goal is to make the drug easier to excrete. The enzymes involved in metabolism are present in many tissues but generally are more concentrated in the liver. Drug metabolism rates vary among patients.

WebAll PPIs are metabolized to varying degrees by hepatic P450 cytochromes (CYP450), including isoenzymes CYP2C19 and CYP3A4, and may interfere with the medications metabolized by these same enzymes.
