What is Amiodarone?
Amiodarone is an antiarrythmic drug, sometimes referred to by its brand names Cordarone and Pacerone, and has been approved for prescription in the United States since 1985. It is most often used only in life-threatening cases of arrhythmia, as it affects the electrical function of the heart by delaying the time period during which the heart “recharges.” It is generally administered (via tablet form) in hospitals, as patients to whom it is prescribed require close monitoring at the outset.
Amiodarone is used to treat people with arrhythmia, or irregular heartbeats, which can manifest as ventricular tachycardia, supraventricular tachycardia, or ventricular fibrillation. Amiodarone works to help keep the heart beating at regular intervals by relaxing overworked heart muscles, which allows blood to be pumped throughout the body more efficiently. Because the drug also causes blood vessels to dilate and blood pressure to drop, it may also be prescribed to people with congestive heart failure.
