Efavirenz reduces renal excretion of lamivudine in rats by inhibiting organic cation transporters (OCT, Oct) and multidrug and toxin extrusion proteins (MATE, Mate)
Fig 1
Inhibition of OCT1-, OCT2-, MATE1-, and MATE2-K-mediated net metformin uptake by efavirenz (0.01–50 μM) in MDCK-OCT1 (A), MDCK-OCT2 (B), MDCK-MATE1 (C), and HEK-MATE2-K (D) cells. Data are shown as means ± SD of at least four experiments performed in triplicate (MDCK cell lines) or three experiments performed in duplicate (HEK-MATE2-K cells). Calculated IC50 values and the associated 95% confidence intervals are shown where appropriate.
