This compound is the oxalate salt of dronedarone, a non-iodinated amiodarone analog primarily utilized in medicinal chemistry and pharmaceutical research for the treatment of atrial fibrillation and other cardiac arrhythmias. It acts as a multichannel blocker, modulating potassium, sodium, and calcium channels to restore normal heart rhythm with a better safety profile than amiodarone. Its structural features make it suitable for managing cardiovascular diseases involving irregular heartbeats. Researchers investigate its efficacy in preventing arrhythmia recurrence, positioning it as a key therapeutic agent in cardiology. Additionally, it serves as an intermediate in synthesizing related antiarrhythmic compounds. The oxalate form improves solubility and stability, aiding in experimental studies, formulations, and oral drug delivery.
