Cordarone (also generically known under the name of Amiodarone) is an antiarrythmic medicine. Cordarone is prescribed in the treatment of heart disorders (it regulates the body's heart rhythm).
Cordarone is mostly prescribed in treatment of irregular pulse (therefore, in the treatment of a wide range of heart disorders). Cordarone can also be prescribed by doctors in the treatment of other medical conditions that have not been mentioned here.
Cordarone is prescribed for severe rhythm disorders when other treatments are not effective or cannot be used.
Cordarone is prescribed to control abnormal heartbeats.
Cordarone is prescribed to treat a variety of different types of fast, abnormal heart rhythms.
Cordarone tablets are available without a brand name, ie as the generic drug.
Cordarone tablets contain the active ingredient amiodarone, which is a type of drug called an antiarrhythmic.
Cordarone works by slowing the electrical impulses in the heart muscle. This helps to regulate and restore disturbances in the heart rhythm.
If the electrical activity in the heart is disturbed for any reason, irregular heartbeats of various types can result.
The electrical signals cause the two pairs of heart chambers to contract in a regular manner that produces the heartbeat.
The heart's pumping action is controlled by electrical signals that pass through the heart muscle.
These can seriously undermine the pumping action of the heart and result in inefficient blood circulation around the body.
Cordarone is prescribed for:
- Fast, abnormal heart rhythms, including supraventricular, nodal and ventricular tachycardias, atrial fibrillation, atrial flutter and ventricular fibrillation, when other drugs cannot be used;
- Fast, abnormal heart rhythms associated with wolff-parkinson-white syndrome;
