Summary
Regorafenib may inhibit the efflux transporter BCRP, and glyburide is a substrate of this transporter. Exposure to glyburide could rise and increase the chance of hypoglycemia, although clinical data are limited.
What this interaction means in plain words
Glyburide and Regorafenib can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Glyburide belongs to Endocrine; Regorafenib belongs to Oncology.
Why it happens
Probable inhibition of BCRP (ABCG2) by regorafenib, reducing efflux of glyburide and increasing its systemic exposure.
What to do
Monitor blood glucose when regorafenib is started and watch for hypoglycemia. Lower the glyburide dose if glucose falls.
