Summary
Both drugs can affect cardiac conduction. Ponesimod slows heart rate and can cause AV conduction delay, which adds to the arrhythmic risk of sunitinib's QT prolongation.
What this interaction means in plain words
Ponesimod and Sunitinib 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.
Ponesimod belongs to Central Nervous System; Sunitinib belongs to Oncology.
Why it happens
Sunitinib prolongs the QT interval and ponesimod causes bradycardia, so the effects on cardiac rhythm are additive.
What to do
Monitor ECG and heart rate, particularly at ponesimod initiation. Correct electrolytes and consider an alternative if the QT interval becomes prolonged.
What to ask your pharmacist
