Summary
Trilaciclib inhibits OCT2, MATE1 and MATE2-K, so metformin concentrations are expected to increase rather than decrease. This may raise the risk of lactic acidosis, particularly with renal impairment.
What this interaction means in plain words
Glyburide-metformin and Trilaciclib can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Glyburide-metformin belongs to Endocrine; Trilaciclib belongs to Oncology.
Why it happens
Trilaciclib inhibits OCT2 and MATE transporters, reducing renal clearance of metformin.
What to do
Avoid metformin on days of trilaciclib where possible, or monitor renal function and lactate-related symptoms closely. Consider a metformin dose reduction.
