Summary
Siponimod causes a transient reduction in heart rate and may slow atrioventricular conduction at initiation. Pindolol, a beta-blocker, adds to this and can increase the risk of symptomatic bradycardia.
What this interaction means in plain words
Pindolol and Siponimod 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.
Why it happens
Additive negative chronotropic effects of S1P receptor modulation and beta-blockade.
What to do
Use caution when starting siponimod in a patient on a beta-blocker, with heart rate monitoring and consideration of temporarily interrupting the beta-blocker. Starting a beta-blocker in a patient on stable siponimod is acceptable.
