Description

Cordarone 200mg

Cordarone 200mg is a potent antiarrhythmic medication primarily used to treat and prevent serious, life-threatening ventricular arrhythmias and atrial fibrillation. Containing Amiodarone Hydrochloride, it works by stabilizing the heart’s rhythm and slowing electrical impulses that cause irregular heartbeats.

Cordarone is typically prescribed when other treatments have proven ineffective. Due to its long half-life, the effects may persist for weeks, even after stopping the drug. Regular monitoring is essential, as it can affect lung, liver, thyroid, and eye function.

Cordarone should be taken exactly as directed by a healthcare provider. Self-medication or abrupt discontinuation is strongly discouraged.

Uses

Cordarone 200mg (Amiodarone) is used to treat and prevent a variety of serious heart rhythm disorders.

• Ventricular Tachycardia – a fast, life-threatening heart rhythm originating from the lower chambers of the heart.
• Ventricular Fibrillation – a chaotic rhythm causing the heart to stop pumping effectively.
• Atrial Fibrillation – an irregular, often rapid heartbeat that can lead to blood clots, stroke, or heart failure.
• Supraventricular Tachycardia (SVT) – a rapid heart rhythm from above the heart’s ventricles.
• Maintaining Normal Heart Rhythm after successful cardioversion (restoring normal rhythm).

How to use it ?

Cordarone 200mg should be taken exactly as prescribed by your doctor. It is usually taken once or twice daily with food to reduce stomach upset. Swallow the tablet whole with a full glass of water—do not crush or chew it.

Take it at the same time each day for best results. Do not stop taking Cordarone without medical advice, as sudden discontinuation may worsen your condition. Regular checkups and monitoring of heart, liver, lung, and thyroid functions are essential.

How dose it works ?

Cordarone 200mg works by affecting the electrical signals in the heart that cause irregular heartbeats. Its active ingredient, Amiodarone, belongs to a class of drugs called antiarrhythmics. It blocks certain electrical signals in the heart muscle, slowing down nerve activity and helping to restore a normal, steady rhythm.

It also prolongs the action potential and refractory period of heart cells, which prevents abnormal impulses from spreading. This helps the heart beat more regularly and efficiently, reducing the risk of life-threatening arrhythmias.

Dosage

The dosage of Cordarone (Amiodarone) varies depending on the condition being treated and the patient’s response. Always follow your doctor’s instructions. Common dosages include:

• Loading Dose (initial phase): 800–1600 mg per day (usually divided into 2–3 doses) for 1–3 weeks.
• Maintenance Dose: Typically 200–400 mg per day, once rhythm is controlled.
• For Atrial Fibrillation or Ventricular Arrhythmias: 200 mg once or twice daily.

Benefits of Cordarone 200mg

• Restores Normal Heart Rhythm – Effectively treats irregular and rapid heartbeats.
• Prevents Life-Threatening Arrhythmias – Reduces the risk of sudden cardiac arrest.
• Long-Lasting Effect – Due to its long half-life, it provides sustained rhythm control.
• Effective When Other Drugs Fail – Often used when other antiarrhythmic medications are ineffective.
• Improves Heart Function – Helps the heart pump more efficiently by maintaining a steady rhythm.
• Reduces Hospitalizations – Lowers the need for emergency interventions due to arrhythmias.

Side Effects of Cordarone 200mg

• Nausea or vomiting
• Fatigue or weakness
• Tremors or unsteadiness
• Slow heartbeat (bradycardia)
• Sensitivity to sunlight (photosensitivity)
• Blue-grey skin discoloration (with long-term use)
• Vision changes (blurred vision, halos)

Serious side effects 

• Liver damage (yellowing of skin/eyes)
• Thyroid problems (weight changes, sweating, fatigue)
• Heart rhythm worsening

Precautions

• Regular Monitoring – Frequent tests are needed to check heart, liver, lung, thyroid, and eye health.
• Avoid Sun Exposure – Use sunscreen and protective clothing, as the drug increases sun sensitivity.
• Inform Your Doctor – Before use, disclose any history of lung, liver, thyroid, or vision problems.
• Avoid Grapefruit – It can increase the level of Amiodarone in your blood, raising side effect risks.
• Pregnancy & Breastfeeding – Not recommended; consult your doctor before use.
• Drug Interactions – Inform your doctor about all medications and supplements you’re taking.
