What are the uses of this medicine?

This medicine is used:

• to treat adults who have chronic (lasting a long time) heart failure, with symptoms, to reduce their risk of hospitalization for worsening heart failure.
• to treat certain children 6 months of age and older who have stable heart failure, with symptoms, that is due to an enlarged heart (dilated cardiomyopathy).

How does this medicine work?

• Ivabradine (eye vab' ra deen) is a small molecule inhibitor of the If ion current, a mixed Na+-K+ inward current that is a major determinant of the sinoatrial pacemaker rate.
• Ivabradine inhibits the If ion current and lowers heart rate but, unlike beta blockers, does not affect cardiac contractility.
• In large clinical trials in patients with heart failure in normal sinus rhythm, ivabradine lowered heart rate and decreased episodes of worsening of heart failure and need for hospitalization.

Who Should Not Use this medicine ?

This medicine cannot be used in patients with:

• symptoms of heart failure that recently worsened
• very low blood pressure (hypotension)
• certain heart conditions: sick sinus syndrome, sinoatrial block, or 3rd degree atrioventricular block
• a slow resting heart rate before treatment with Corlanor. Ask your doctor what a slow resting heart rate is for you.
• certain liver problems
• been prescribed any medicines that can increase the effects of Corlanor.

What drug interactions can this medicine cause?

• The concomitant use of strong CYP3A4 inhibitors is contraindicated . Examples of strong CYP3A4 inhibitors include azole antifungals (e.g., itraconazole), macrolide antibiotics (e.g., clarithromycin, telithromycin), HIV protease inhibitors (e.g., nelfinavir), and nefazodone.
• Avoid concomitant use of moderate CYP3A4 inhibitors when using Corlanor. Examples of moderate CYP3A4 inhibitors include diltiazem, verapamil, and grapefruit juice.
• Avoid concomitant use of CYP3A4 inducers when using Corlanor. Examples of CYP3A4 inducers include St. John’s wort, rifampicin, barbiturates, and phenytoin.
• The risk of bradycardia increases with concomitant administration of drugs that slow heart rate (e.g., digoxin, amiodarone, beta-blockers). Monitor heart rate in patients taking Corlanor with other negative chronotropes.
• The use of Corlanor is not recommended in patients with demand pacemakers set to rates ≥ 60 beats per minute.

Is this medicine FDA approved?

• It was approved for use in the United States in 2015.

How should this medicine be used?

Recommended Dosage: Adult and pediatric patients greater than 40 kg

• Starting dose is 2.5 (pediatrics and vulnerable adults) or 5 mg twice daily with food. After 2 weeks of treatment, adjust dose based on heart rate. The maximum dose is 7.5 mg twice daily.

Pediatric patients less than 40 kg

• Starting dose is 0.05 mg/kg twice daily with food. Adjust dose at two-week intervals by 0.05 mg/kg based on heart rate. Maximum dose is 0.2 mg/kg (patients 6 months to less than 1 year old) or 0.3 mg/kg (patients 1 year old and older), up to a total of 7.5 mg twice daily.
