Summary
Both drugs can prolong the QT interval, so using them together may add to the risk of ventricular arrhythmia including torsades de pointes. Risk rises with higher doses, electrolyte disturbances or underlying heart disease.
What this interaction means in plain words
Buprenorphine and Eliglustat 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.
Buprenorphine belongs to Musculoskeletal; Eliglustat belongs to Miscellaneous.
Why it happens
Additive QTc prolongation through pharmacodynamic effects on cardiac repolarization.
What to do
Obtain a baseline ECG and monitor QTc during combined use, correcting potassium and magnesium. Consider an alternative if QTc becomes markedly prolonged or the patient has other risk factors.
