Amiodarone is a medication primarily used to treat certain types of serious irregular heartbeats, known as arrhythmias. It works by stabilizing the electrical activity in the heart, helping to restore a normal rhythm. This drug is often prescribed for patients with conditions like ventricular tachycardia or atrial fibrillation. Amiodarone can be administered orally or intravenously, depending on the severity of the condition. While it can be effective, it may also cause side effects, including lung problems, liver issues, and changes in thyroid function. Regular monitoring is essential for patients taking this medication.
