      Drug Name Amisulpride Siponimod
      Mechanism Prolong QT interval Bradycardia
      Key Mechanism Factor 1
Factor Name Ventricular arrhythmias
Factor Description Ventricular arrhythmias are abnormal heart rhythms that cause your heart's lower chambers to pump blood instead of pumping it. This can limit or stop your heart from supplying blood to your body. While some of these arrhythmias are harmless and do not cause symptoms, others can have serious, even fatal, effects on your body.
      Mechanism Description
  • Increased risk of ventricular arrhythmias by the combination of Amisulpride and Siponimod 

Recommended Action
      Management Siponimod has not been studied in patients receiving drugs that can prolong the QT interval. Because bradycardia and AV block are recognized risk factors for QT prolongation and torsade de pointes arrhythmia, treatment with siponimod should generally not be initiated in patients who are concurrently treated with QT prolonging drugs with known arrhythmogenic properties.
