Have you or someone in your family ever been told by a doctor that your heart is beating too fast, too fast, or too irregularly? If so, you may have heard of a medication called Amiodarone. It is a powerful, yet very important drug. So, it is important to be well-informed about this medication. Let's talk about it simply.
Simply put, what is Amiodarone?
Amiodarone is a drug that is used to treat and prevent a fast or irregular heartbeat (a condition medically known as arrhythmia ). Think about it, our heart is controlled by a small electrical signal system. Sometimes, this signal system can become overactive, causing the heart to beat irregularly. That's when the heart's rhythm becomes disturbed.
Amiodarone injection works by controlling those unwanted electrical signals and stabilizing the heart's rhythm. It belongs to a class of drugs called antiarrhythmics .
This medicine is usually given as an injection into a vein. It is also given only in a hospital or clinic, under the direct supervision of a trained medical team.
