What is Ivabradine for?
Ivarbradine belongs to a class of medication called selective sinus node If channel inhibitors. It can regulate the electrical signals in the heart and slow down heart rate so the heart can pump more blood when it contracts. It is mainly used to treat heart failure and reduce the risk of hospitalization for worsening heart failure. On the other hand, it has been suggested to be a second-line treatment for stable angina (off-label use).

Ivabradine can be taken orally as tablets.
The usual initial dose is 5 mg twice daily. After 2-4 weeks taking the medication, adjust the dose based on heart rate (refer below) to achieve a resting heart rate between 50-60 beats per minute (bpm).
Note: A lower initial dose may be required in some special conditions (e.g. history of conduction defects)
Heart rate > 60 bpm:

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
5 mg twice daily, and can be increased after 3-4 weeks if symptoms persist and heart rate is >60 bpm, up to 7.5 mg twice daily.
