Indications
Cordarone is scientifically known as amiodarone HCl and is a prescription drug used to control and treat the symptoms of irregular heart rhythm (Ventricular Arrhythmias). It is classified as a class III antiarrhythmic medication, and it works partly by increasing the time before a heart cell can contract.
Amiodarone works by blocking certain electrical signals in the heart that can cause an irregular heartbeat. By doing this, it helps to correct the rhythm of your heart and stabilize your heart rate.
Uses and Dosage
Cordarone is available in tablet form for oral administration. A typical prescription dosage is one or two tablets daily, and patients may take the medication with or without meals, as directed by their healthcare provider. Swallow the tablet whole with a glass of water, and the pill should not be chewed, cut, or crushed.
To ensure the best results, take Cordarone regularly and according to the prescribed dosing schedule. Patients should not make any changes to their dosage or frequency without consulting their healthcare provider, as this can vary based on their medical condition and response to treatment. Abruptly discontinuing Cordarone can potentially worsen the condition, and patients should follow their healthcare provider's instructions if they need to stop taking the medication.
To initiate treatment with Cordarone, a loading dose in the range of 800 to 1600 mg per day is typically prescribed until the patient achieves an initial therapeutic response. This period often lasts between one and three weeks. Once adequate control of arrhythmia is achieved, or if serious side effects become apparent, the Cordarone dose should be reduced to 600 to 800 mg per day for one month. Subsequently, the maintenance dose, which is typically 400 mg per day, can be prescribed.
