Randomized Controlled Trial Multicenter StudyInteraction between digoxin and dronedarone in the PALLAS trial.
Elevated serum digoxin concentration can cause toxicity, including death. Dronedarone increases digoxin concentration by P-glycoprotein interaction. In Permanent Atrial Fibrillation Outcome Study Using Dronedarone On Top Of Standard Therapy Trial (PALLAS), dronedarone was associated with both increased cardiovascular death and heart failure in patients with permanent atrial fibrillation. The present analysis examines whether the dronedarone-digoxin interaction might explain these adverse outcomes. ⋯ http://www.clinicaltrials.gov. Unique identifier: NCT01151137.
