Abstract

Metformin and berberine are often combined for treating diabetes. In the present study, we evaluated the drug-drug pharmacokinetic interaction between metformin and berberine after oral co-administration in vivo and the underlying mechanism. As revealed by comparison with the metformin-only group, berberine significantly decreased the maximum plasma concentration (C max), area under the curve from 0 to 4 h (AUC 0-4h), and urinary and bile excretion, and increased the kidney tissue concentration of metformin in rats. The non-everted intestinal sac study showed that berberine inhibited the absorption of metformin, and in transfected Madin-Darby canine kidney (MDCK)-rat organic cation transporter 1 (MDCK-rOCT1), MDCK-rat organic cation transporter 2 (MDCK-rOCT2), and MDCK-rat multidrug and toxin extrusion 1 (MDCK-rMATE1) cells, berberine significantly inhibited metformin transport mediated by OCT1, OCT2, and MATE1 in a concentration-dependent manner with half-maximal inhibitory concentration (IC 50) values of 18.8, 1.02, and 10.7 μM, respectively. In contrast, co-administration of metformin increased the C max and AUC 0-4h of berberine with no significant difference in pharmacokinetics parameters between co-administration and berberine-only groups. Furthermore, metformin increased kidney and liver concentrations and reduced the urinary and biliary excretion of berberine. Metformin (≥1 or ≥0.3 mM) decreased berberine transport in MDCK-rOCT1, MDCK-rOCT2, and MDCK-rMATE1 cells. However, metformin did not affect berberine concentration in MDCK-multidrug resistance protein 1 cells. These results suggest that the combination of metformin and berberine induced a pharmacokinetic interaction by cooperatively inhibiting OCT and MATE1-mediated transport.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
