Amiodarone is an antiarrhythmic medication that is available in oral as well as injectable form and is prescribed for patients suffering from irregular heart rhythm. Despite having several side effects, a number of them being serious and even probably fatal, amiodarone is effective in curing several arrhythmias (anomalies in the rhythm of heartbeat) when other antiarrhythmic medications fail to yield the desired results. This medication is regarded as a 'broad spectrum' or wide-ranging antiarrhythmic medication because it has manifold as well as compound results on the heart's electrical activity that controls the rhythm of heartbeats.
Amiodarone has numerous significant electrical effects on the rhythm of the heart and some of them are discussed here. This medication causes a lingering in the pace of refreshing the electrical system of the heart following its contraction (a condition called re-polarization). Amiodarone also inhibits the pace of conducting electricity - the rate at which individual impulses are transmitted through the electrical system of the heart. It also prolongs the electrical stage when the muscle cells of the heart are stimulated electrically (also called the action potential) and retards the speed at which standard generator of electrical impulses are fired in the heart (acting like the pacemaker of the heart). Amiodarone also inhibits conduction by means of a variety of specific electrical conduits (referred to as accessory pathways) that may possibly cause arrhythmias.
Besides being an antiarrhythmic drug, amiodarone also works to dilate or widen the blood vessels making blood circulation much easier. This action of the medication may lead to a decline in blood pressure and, hence, it may perhaps be beneficial for patients having congestive heart failure.
While scientists discovered amiodarone in 1961, the Food and Drug Administration (FDA) approved the sale and use of this drug in the United States in 1985.
