Corlentor 5 mg film-coated tablets


What is it and how is it used?

Corlentor (ivabradine) is a heart medicine used to treat stable angina pectoris which causes chest pain. It is used in adult patients who do not tolerate or cannot take heart medicines called beta-blockers. It is also used in combination with beta-blockers in adult patients whose condition is not fully controlled with a beta-blocker and whose heart rate is too high (over 60 beats per minute).

About stable angina pectoris (usually referred to as “angina”):
Stable angina is a heart disease which happens when the heart does not receive enough oxygen. It usually appears between 40 and 50 years of age. The most common symptom of angina is chest pain or discomfort. Angina is more likely to happen when the heart beats faster in situations such as exercise, emotion, exposure to the cold or after eating. This increase in heart rate can cause the chest pain in people who suffer from angina.

How does Corlentor work?
Corlentor mainly works by reducing the heart rate by a few beats per minute. This lowers the heart’s need for oxygen especially in the situations when an angina attack is more likely to happen. In this way Corlentor helps to control and reduce the number of angina attacks.

What do you have to consider before using it?

Do not take Corlentor

  • if you are allergic (hypersensitive) to ivabradine or any of the other ingredients of Corlentor (see “further information” for a list of all ingredients);
  • if your resting heart rate before treatment is too slow (below 60 beats per minute);
  • if you are suffering from cardiogenic shock (a heart condition treated in hospital);
  • if you suffer from a heart rhythm disorder;
  • if you are having a heart attack;
  • if you suffer from very low blood pressure;
  • if you suffer from unstable angina (a severe form in which chest pain occurs very frequently and with or without exertion);
  • if you suffer from severe heart failure (when your heart fails to work properly);
  • if you have a pacemaker;
  • if you suffer from severe liver problems;
  • if you are already taking medicines for the treatment of fungal infections (such as ketoconazole, itraconazole), macrolide antibiotics (such as josamycin, clarithromycin, telithromycin or erythromycin given orally), medicines to treat HIV infections (such as nelfinavir, ritonavir) or nefazodone (medicine to treat depression) (see “Taking other medicines”);

What is it?

Corlentor is a medicine that contains the active substance ivabradine. It is available as salmon-coloured tablets (oblong: 5 mg; triangular: 7.5 mg). The 5-mg tablets have a score line that enables them to be divided into two equal halves, each containing 2.5 mg ivabradine.

What is it used for?

Corlentor is used to treat the symptoms of long-term stable angina (pains to the chest, jaw and back, brought on by physical effort and due to problems with the blood flow to the heart). It is used in adults (aged 18 years or over) with coronary artery disease (obstruction of the blood vessels that supply the heart) who have a normal sinus rhythm (heartbeat). It can be used in the following groups:

  • patients who cannot take or tolerate beta-blockers (another type of medicine to treat angina);
  • patients whose disease is not controlled with beta-blockers and whose heart rate is above 60 beats per minute. Corlentor is used in combination with beta-blockers in these patients.

The medicine can only be obtained with a prescription.

How is it used?

Corlentor is taken twice a day with meals, once in the morning and once in the evening.

The recommended starting dose is 5 mg twice a day, although 2.5 mg twice a day can be used in patients over the age of 75 years, before the dose is increased to 5 mg twice a day. After three to four weeks of treatment, the dose may be increased to 7.5 mg twice a day depending on the patient’s response.

How does it work?

The symptoms of angina are caused by the heart not receiving enough oxygenated blood. In stable angina, these symptoms appear during physical effort. The active substance in Corlentor, ivabradine, works by blocking the ‘I f currents’ in the sinus node, the ‘pacemaker’ for the heart that controls the heart’s contractions and regulates the heart rate. When these currents are blocked, the heart rate is lowered, so that the heart has less work to do and needs less oxygenated blood. Corlentor therefore reduces or prevents the symptoms of angina.

How has it been studied?

Corlentor has been studied in five main studies involving over 4,000 adults with long-term stable angina. The medicine was compared with placebo (a dummy treatment) in 360 patients, atenolol (a beta-blocker) in 939 patients and amlodipine (another medicine used to treat angina) in 1,195 patients. It was also compared with placebo as an add-on to atenolol in 889 patients and as an add-on to amlodipine in 728 patients. Each study lasted three to four months. The main measure of effectiveness was how long the patients could exercise on a bicycle or a treadmill, measured at the start and the end of each study.

What benefits has it shown during the studies?

Corlentor was more effective than placebo at improving exercise capacity and was as effective as atenolol and amlodipine. Corlentor was also more effective than placebo when added to atenolol. However, adding Corlentor to amlodipine did not provide an additional benefit.

What is the risk associated?

The most common side effect with Corlentor (seen in more than 1 patient in 10) is luminous phenomena or ‘phosphenes’ (a temporary brightness in the field of vision). For the full list of all side effects reported with Corlentor, see the package leaflet.

Corlentor should not be used in people who may be hypersensitive (allergic) to ivabradine or any of the other ingredients. It must not be used in patients who have a resting heart rate below 60 beats per minute, very low blood pressure, various types of heart disorder (cardiogenic shock, rhythm disorders, heart attack or heart failure) or severe liver problems. It must not be used in women who are pregnant or breast-feeding. For the full list of restrictions, see the package leaflet.

Caution is needed if Corlentor is taken with some other medicines. See the package leaflet for full details.

Why has it been approved?

The CHMP concluded that Corlentor has sufficient effectiveness against angina and an acceptable safety profile for it to provide an alternative treatment for patients who cannot take beta-blockers or whose disease is not controlled with them. The Committee decided that Corlentor’s benefits are greater than its risks and recommended that it be given marketing authorisation.

Further information

The European Commission granted a marketing authorisation valid throughout the European Union for Corlentor to Les Laboratoires Servier on 25 October 2005. The marketing authorisation is valid for an unlimited period.
