Summary
Ceritinib commonly causes hyperglycemia, which can work against the glucose-lowering effect of the linagliptin-metformin combination. Ceritinib is also a CYP3A4 inhibitor, but the effect on linagliptin exposure is expected to be modest and of limited importance.
What this interaction means in plain words
Ceritinib and Linagliptin-metformin 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.
Ceritinib belongs to Oncology; Linagliptin-metformin belongs to Endocrine.
Why it happens
Ceritinib-associated hyperglycemia opposes antidiabetic therapy, and ceritinib may weakly raise linagliptin levels through CYP3A4 and P-gp inhibition.
What to do
Monitor blood glucose and HbA1c during ceritinib therapy and intensify antidiabetic treatment if glycemic control worsens.
