Résumé

Both drugs interact with P-glycoprotein. Berotralstat inhibits P-gp and can increase amiodarone exposure, and amiodarone may in turn raise berotralstat levels. Berotralstat also prolongs QT at higher doses, which adds to amiodarone's own QT effect.

Ce que signifie cette interaction, en termes simples

Amiodarone and Berotralstat 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.

Amiodarone belongs to Cardiovascular; Berotralstat belongs to Miscellaneous.

Niveau de preuve: Moderate

Pourquoi elle survient

Mutual P-gp inhibition raises exposure to both drugs, with additive QT prolongation as a pharmacodynamic contribution.

Conduite à tenir

Monitor ECG for QTc prolongation and watch for amiodarone toxicity such as bradycardia. Correct potassium and magnesium abnormalities.
