Indications
Symptomatic treatment of chronic stable angina pectoris in coronary artery disease patients with normal sinus rhythm. Ivabradine is indicated:
- In patients unable to tolerate or with a contra-indication to the use of beta-blockers or
- In combination with beta-blockers in patients inadequately controlled with an optimal beta-blocker dose and whose heart rate is > 60 bpm.
Therapeutic Class
Pharmacology
Dosage & Administration
Adult: The usual recommended starting dose of Ivabradine is 5 mg twice daily which may be increased after 3-4 weeks of treatment to 7.5 mg twice daily, depending on therapeutic response. Usual dose is 1 tablet in the morning and 1 tablet in the evening during meals.
If the heart rate decreases persistently below 50 bpm at rest or if symptoms related to bradycardia, the dose must be adjusted downwards to 2.5 mg twice daily (one half of the 5 mg tablet twice daily). Treatment must be discontinued if heart rate remains below 50 bpm or symptoms of bradycardia persist.
Elderly: Consider a lower starting dose (2.5 mg twice daily i.e. one half 5 mg tablet twice daily).
Children and adolescents: Not recommended.
Interaction
QT wave prolonging medicinal products is not recommended. Cardiovascular QT wave prolonging medicinal products (e.g. quinidine, disopyramide, bepridil, sotalol, ibutilide, amiodarone). Non cardiovascular QT wave prolonging medicinal products (e.g. pimozide, ziprasidone, sertindole, mefloquine, halofantrine, pentamidine, cisapride, intravenous erythromycin).
The concomitant use of cardiovascular and non cardiovascular QT wave prolonging medicinal products with ivabradine should be avoided since QT wave prolongation may be exacerbated by heart rate reduction. If the combination appears necessary, close cardiac monitoring is needed.
