Expanded Pharmacokinetics Pathways for PPIs

The Proton Pump Inhibitor Pathway, Pharmacokinetics has been updated and expanded to now highlight four pathways with candidate genes and drug metabolites involved for:

Omeprazole and esomeprazole, 

Lanzoprazole and dexlansoprazole, 

Pantoprazole and 

Rabeprazole. 

The pathways illustrate the subtle differences between the metabolism of drugs in the class, their different sensitivities to variation in CYP2C19, and aids explanation of the differences in CPIC recommendations for the different drugs (see CPIC Guideline for CYP2C19 and Proton Pump Inhibitor Dosing).
