dc.description.abstract | The interaction between proton pump inhibitors (PPIs) and clopidogrel/prasugrel was investigated. The IC50 values of omeprazole, esomeprazole, lansoprazole, pantoprazole and rabeprazole on the metabolic ratios of 2-oxo-clopidogrel/clopidogrel, H4 (the active metabolite of clopidogrel)/2-oxo-clopidogrel and R-138727 (the active metabolite of prasugrel)/prasugrel thiolactone in human liver microsomes were determined. The antiplatelet activities of clopidogrel and prasugrel were measured with or without PPIs. As a result, most PPIs (except for pantoprazole) inhibited the formation of 2-oxo-clopidogrel with IC50 values of 2032 mu m and inhibited the formation of H4 with IC50 values of 620 mu m. PPIs inhibited the formation of R-138727 with IC50 values of 925 mu m. Among the tested PPIs, omeprazole exhibited the highest inhibitory potency on the formation of H4. Omeprazole, esomeprazole and rabeprazole exhibited the highest inhibitory potencies on the formation of R-138727. For platelet aggregation, omeprazole and lansoprazole show higher inhibitory effects on the antiplatelet activity of clopidogrel. On the other hand, omeprazole, esomeprazole and rabeprazole significantly decreased the antiplatelet activity of prasugrel thiolactone. These data indicate that PPIs differ in their effects of inhibiting the metabolism and antiplatelet activities of clopidogrel and prasugrel. Copyright (c) 2012 John Wiley & Sons, Ltd. | en |
