What Is Amiodarone Premixed Injection Used For?
Amiodarone premixed injections are given to treat potentially serious heart rhythm problems in adults. This medication works by affecting certain electrical signals in the heart, which can help stabilize the heart rate and maintain a regular rhythm. There are also off-label uses for amiodarone premixed injection, such as treating arrhythmias in children and mild-to-severe angina.
An Overview of Uses for Amiodarone Premixed InjectionAmiodarone premixed injection (Nexterone®) is a prescription antiarrhythmic medication. It is approved to treat and prevent life-threatening heart rhythm problems known as ventricular arrhythmias. Amiodarone premixed injection is reserved for use in people who did not adequately respond to other medications.
What Are Ventricular Arrhythmias?A ventricular arrhythmia is an arrhythmia that originates in the lower chambers of the heart (the ventricles). Not all ventricular arrhythmias are life-threatening. Amiodarone premixed injection is only approved to treat or prevent ventricular tachycardia or ventricular fibrillation, types of life-threatening ventricular arrhythmias.
Ventricular tachycardia is a type of arrhythmia in which the ventricles beat very quickly, often causing a heart rate in excess of 120 beats a minute. As a result, the ventricles may be unable to pump blood out to the rest of the body, potentially depriving important body organs of the oxygen-rich blood they need to function properly.
If ventricular tachycardia does not resolve, it may turn into ventricular fibrillation. Ventricular fibrillation is an extremely dangerous heart rhythm problem. During ventricular fibrillation, the ventricles beat in a very fast and disorganized manner, causing them to quiver, or fibrillate. Ventricular fibrillation must be treated immediately to prevent death.
Amiodarone premixed injection is used to return the heart to a normal rhythm in people who have recurring episodes of ventricular tachycardia or ventricular fibrillation. Amiodarone premixed injection contains the active ingredient amiodarone. Amiodarone is also available in tablet form (Cordarone®, Pacerone®). Once the heart arrhythmia is under control, a healthcare provider may recommend a person switch to amiodarone tablets to help keep the heart beating normally.
