Summary
Ponesimod can slow heart rate and prolong atrioventricular conduction, while sertraline has a modest, dose-related QT-prolonging effect. Together they may add to the risk of bradycardia and arrhythmia, particularly in patients with existing cardiac disease.
What this interaction means in plain words
Ponesimod and Sertraline 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; Sertraline belongs to Central Nervous System.
Why it happens
Additive pharmacodynamic effects on cardiac conduction and repolarization; ponesimod causes S1P-mediated bradycardia and sertraline mildly prolongs QTc.
What to do
Obtain a baseline ECG before starting ponesimod and monitor heart rate and QTc, especially in patients with cardiac risk factors or electrolyte disturbances. Consider specialist advice if other QT-prolonging or bradycardic drugs are also used.
