What is Coralan?

Coralan is a brand product that contains Ivabradine, which belongs to a class of medication called antiarrhythmics. It works by regulating the electrical signals in the heart to slow down heart rate. As a result, the heart can pump more blood during contraction. It is therefore used to treat heart failure and reduce the risk of hospitalization due to worsening heart failure. 

How to use it?

Coralan is available as tablets. 

For heart failure, the starting dose is 5mg twice a day. Gradually increase the dose during the intervals of 2-4 weeks depending on the response in heart rate. Treatment should aim to achieve a resting heart rate between 50-60 beats per minute (bpm). 

Heart rate > 60 bpm: 
Increase dose by 2.5 mg twice daily up to a maximum dose of 7.5 mg twice daily

Heart rate 50-60 bpm: 
Maintain the current dose

Heart rate < 50 bpm or signs and symptoms of bradycardia:
Decrease dose by 2.5 mg twice daily; if current dose is 2.5 mg twice daily, discontinue therapy.

What are the side effects of Coralan?

The common side effects of Coralan include slow heart rate, hypertension, atrial fibrillation and visual disturbance.

Who should not take Coralan?

  • Anyone who is allergic to any component of Coralan
  • Patients with severe hypotension, severe bradycardia, severe hepatic impairment
  • Patients with certain heart conditions, such as acute decompensated heart failure, heart block
