In vitro hæmmede sitagliptin ikke OAT3 (IC50=160 µM) eller p- glycoprotein (op til 250 µM) medieret transport ved terapeutisk relevante plasmakoncentrationer.
In vitro, sitagliptin did not inhibit OAT3 (IC50=160 μ M) or p-glycoprotein (up to 250 μ M) mediated transport at therapeutically relevant plasma concentrations.
