Summary

Ozanimod can slow heart rate and conduction, and ranolazine prolongs the QT interval. Together they may add to arrhythmia risk, particularly bradycardia-related torsades.

What this interaction means in plain words

Ozanimod and Ranolazine 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.

Ozanimod belongs to Central Nervous System; Ranolazine belongs to Cardiovascular.

Evidence level: Low

Why it happens

Additive effects on cardiac conduction and repolarisation, with ozanimod-induced bradycardia increasing the risk of QT-related arrhythmia.

What to do

Obtain an ECG before starting ozanimod. Seek cardiology advice before starting it in a patient on ranolazine, and monitor heart rate and QTc.
