Patient leaflet - IVABRADINE CHANELLE MEDICAL 5 MG FILM-COATED TABLETS

1. what ivabradine is and what it is used for

Ivabradine is a heart medicine used to treat:

  • – Symptomatic stable angina pectoris (which causes chest pain) in adult patients whose heart rate is over or equal to 70 beats per minute. 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.

  • – Chronic heart failure in adult patients whose heart rate is over or equal to 75 beats per minute. It is used in combination with standard therapy, including beta-blocker therapy or when beta-blockers are contraindicated or not tolerated.

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.

About chronic heart failure:

Chronic heart failure is a heart disease which happens when your heart cannot pump enough blood to the rest of your body. The most common symptoms of heart failure are breathlessness, fatigue, tiredness and ankle swelling.

How does Ivabradine work?

Ivabradine 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 Ivabradine helps to control and reduce the number of angina attacks.

Furthermore as elevated heart rate adversely affects the heart functioning and vital prognosis in patients with chronic heart failure, the specific heart rate lowering action of Ivabradine helps to improve the heart functioning and vital prognosis in these patients.

2. what you need to know before you take ivabradine

Do not take Ivabradine:

  • if you are allergic to Ivabradine or any of the other ingredients of this medicine (listed in section 6);

  • 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 have heart failure which has recently become worse;
  • If your heartbeat is exclusively imposed by your 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) or diltiazem, verapamil (used for high blood pressure or angina pectoris);

Warnings and precautions

Talk to your doctor or pharmacist before taking Ivabradine:

  • if you suffer from heart rhythm disorders (such as irregular heartbeat, palpitation, increase in chest pain) or sustained atrial fibrillation (a type of irregular heartbeat), or an abnormality of electrocardiogram (ECG) called ‘long QT syndrome’;
  • if you have symptoms such as tiredness, dizziness or shortness of breath (this could mean that your heart is slowing down too much);
  • if you suffer from symptoms of atrial fibrillation (pulse rate at rest unusually high (over 110 beats per minute) or irregular, without any apparent reason, making it difficult to measure);
  • if you have had a recent stroke (cerebral attack);
  • if you suffer from mild to moderate low blood pressure;
  • if you suffer from uncontrolled blood pressure, especially after a change in your antihypertensive treatment;
  • if you suffer from severe heart failure or heart failure with abnormality of ECG called ‘bundle branch block’;
  • if you suffer from chronic eye retinal disease;
  • if you suffer from moderate liver problems;
  • if you suffer from severe renal problems;

3. how to take ivabradine

Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.

Ivabradine should be taken during meals.

The 5 mg tablet can be divided into equal doses.

If you are being treated for stable angina pectoris

The starting dose should not exceed one tablet of Ivabradine 5 mg twice daily. If you still have angina symptoms and if you have tolerated the 5 mg twice daily dose well, the dose may be increased. The maintenance dose should not exceed 7.5 mg twice daily. Your doctor will prescribe the right dose for you. The usual dose is one tablet in the morning and one tablet in the evening. In some cases (e.g. if you are elderly), your doctor may prescribe half the dose i.e., one half 5 mg tablet of Ivabradine 5 mg (corresponding to 2.5 mg ivabradine) in the morning and one half 5 mg tablet in the evening.

If you are being treated for chronic heart failure

The usual recommended starting dose is one tablet of Ivabradine 5 mg twice daily increasing if necessary to one tablet of Ivabradine 7.5 mg twice daily. Your doctor will decide the right dose for you. The usual dose is one tablet in the morning and one tablet in the evening. In some cases (e.g. if you are elderly), your doctor may prescribe half the dose i.e., one half 5 mg tablet of Ivabradine 5 mg (corresponding to 2.5 mg ivabradine) in the morning and one half 5 mg tablet in the evening.

If you take more Ivabradine than you should:

A large dose of Ivabradine could make you feel breathless or tired because your heart slows down too much. If this happens, contact your doctor immediately.

If you forget to take Ivabradine:

If you forget to take a dose of Ivabradine, take the next dose at the usual time. Do not take a double dose to make up for the forgotten dose.

The calendar printed on the blister containing the tablets should help you remember when you last took a tablet of Ivabradine.

If you stop taking Ivabradine:

As the treatment for angina or chronic heart failure is usually life-long, you should discuss with your doctor before stopping this medicinal product.
