Summary
Racemic epinephrine, a sympathomimetic, can provoke tachyarrhythmias, and QT effects are minor and mostly theoretical. Combined use with dronedarone may add to arrhythmic risk in susceptible patients.
What this interaction means in plain words
Dronedarone and Epinephrine racemic 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
Adrenergic stimulation may cause arrhythmia and add to dronedarone's repolarization effects.
What to do
Monitor heart rhythm and blood pressure with systemic use. Inhaled use at usual doses rarely needs a change.
