Summary
Both drugs can prolong the QTc interval, so using them together may raise the risk of torsades de pointes. The risk is greater with electrolyte disturbances or underlying heart disease.
What this interaction means in plain words
Amitriptyline and Romidepsin 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 prolongation of cardiac repolarization through effects on cardiac ion channels.
What to do
Obtain a baseline ECG and repeat it during treatment, and correct potassium and magnesium before and during therapy. Consider an alternative antidepressant if the QTc becomes markedly prolonged.
