Summary
Ponesimod lowers heart rate on initiation, and verapamil also slows sinus and AV node function. Together they can cause pronounced bradycardia and conduction block.
What this interaction means in plain words
Ponesimod and Verapamil 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.
Ponesimod belongs to Central Nervous System; Verapamil belongs to Cardiovascular.
Why it happens
Additive heart-rate lowering from S1P receptor modulation and calcium channel blockade at the sinus and AV nodes.
What to do
Avoid starting ponesimod in patients on verapamil unless a cardiologist advises. If treated, switch to a non-rate-lowering drug when possible or use ECG monitoring at initiation.
