Antiarrhythmic medications are drugs used to treat irregular heartbeats, known as arrhythmias. These medications work by stabilizing the electrical activity of the heart, helping to restore a normal rhythm. They can be classified into different categories based on their mechanism of action, such as sodium channel blockers and beta-blockers. Commonly prescribed antiarrhythmics include amiodarone, sotalol, and flecainide. These drugs can be administered orally or intravenously, depending on the severity of the arrhythmia. While effective, antiarrhythmics may have side effects and require careful monitoring by healthcare professionals to ensure patient safety.
