Dronedarone hydrochloride is a class III antiarrhythmic medication used to maintain normal heart rhythm in adults with a history of atrial fibrillation or atrial flutter. It helps reduce the risk of hospitalization due to these rhythm disorders. The drug is given orally as a 400 mg tablet taken twice daily with food. It works by blocking multiple cardiac ion channels to stabilize electrical activity in the heart. Dronedarone is an alternative to amiodarone with a modified chemical structure aimed at reducing certain toxicities.

Product Description:

Dronedarone hydrochloride is a small‑molecule antiarrhythmic medication indicated primarily for adults with a history of paroxysmal or persistent atrial fibrillation or atrial flutter who are in normal sinus rhythm and at risk of recurrence. It is used to help maintain normal heart rhythm and reduce the risk of hospitalization due to arrhythmia. Dronedarone belongs to the class III antiarrhythmic group and exhibits multichannel blocking effects on potassium, sodium, and calcium channels, and has additional antiadrenergic properties. Compared with its related drug amiodarone, dronedarone lacks iodine moieties, which is intended to reduce the risk of thyroid and pulmonary toxicities associated with amiodarone. The medication is supplied in 400 mg film‑coated tablets, typically taken twice daily with meals to improve absorption. While it can be effective in rhythm control, dronedarone must be used cautiously due to potential side effects, including liver injury and interactions with other medications. It is contraindicated in certain patients, such as those with severe heart failure or permanent atrial fibrillation. In the United States, it is marketed under the brand Multaq, and similar branded and generic forms are available in the European Union and United Kingdom.
