WebThe objective of this study was to evaluate the DDI potential of evogliptin using various in vitro assays in transporter-expressing cell lines. After incubating evogliptin with cells overexpressing OAT1, OAT3, OCT2, OATP1B1 and OATP1B3, there was no notable cellular accumulation of evogliptin (fold accumulation, 0.41-1.86).
