Irbesartan - un inhibiteur des récepteurs de l'angiotensine

About irbesartan

Irbesartan is an angiotensin receptor blocker. It is also called an angiotensin-II receptor antagonist, or an AIIRA. It is used to treat high blood pressure (hypertension). People with high blood pressure usually do not feel unwell, but if left untreated, high blood pressure can harm the heart and damage blood vessels.

Irbesartan works by blocking the effect of a chemical called angiotensin II. Angiotensin II causes your blood vessels to narrow, so by blocking its effect, irbesartan allows your blood vessels to relax and widen. As this happens, the pressure within your blood vessels is reduced. Irbesartan also has a protective function on the kidneys of people with type 2 diabetes who have high blood pressure.

Irbesartan may be prescribed on its own to treat high blood pressure, or you may also be given other medicines to take alongside it. This is because a combination of medicines which work in different ways can often lower your blood pressure more than one medicine on its own. One brand of tablet called CoAprovel® contains hydrochlorothiazide as well as irbesartan - being prescribed a combination brand like this will help to reduce the number of tablets you need to take each day.

Before taking irbesartan

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking irbesartan it is important that your doctor knows:

• Si vous êtes enceinte, si vous essayez d'avoir un enfant ou si vous allaitez.

• Si vous avez un problème avec vos reins, en particulier s'il s'agit d'une obstruction de l'artère qui alimente vos reins en sang.

• Si vous souffrez de diabète sucré.

• Si vous avez des problèmes au niveau des valves cardiaques ou du muscle cardiaque.

• Si vous prenez d'autres médicaments. Cela inclut tous les médicaments que vous prenez et qui sont disponibles sans ordonnance, ainsi que les médicaments à base de plantes et les médicaments complémentaires.

• Si vous avez déjà eu une réaction allergique à un médicament.

How to take irbesartan

• Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about irbesartan and will provide you with a full list of the side-effects which you may experience from taking it.

• Take irbesartan once each day, exactly as your doctor tells you to. There are several different strengths of tablet available (75 mg, 150 mg and 300 mg) - your doctor will tell you which strength of tablet is right for you.

• Try to take irbesartan at the same time of day each day. This will help you to remember to take your doses regularly.

• Swallow the tablet with a drink of water. You can take irbesartan before or after meals.

• Si vous oubliez de prendre une dose, prenez-la dès que vous vous en rendez compte. Si vous ne vous en rendez compte que le lendemain, ne prenez pas la dose oubliée. Ne prenez pas deux doses en même temps pour compenser une dose oubliée.

Tirer le meilleur parti de votre traitement

• Try to keep your regular appointments with your doctor. This is so your progress can be monitored and your blood pressure measured. Your doctor may want you to have some blood tests from time to time to check on your kidneys, and also on how much potassium is in your blood.

• Each time you collect a prescription, check to make sure it is the strength of tablet that you are expecting.

• If you buy any medicines, check with a pharmacist that they are suitable to take with irbesartan. This is because some anti-inflammatory painkillers (such as aspirin and ibuprofen) may interfere with the way it works, and also may increase the risk of side-effects.

• Il est très important que vous suiviez les conseils de votre médecin en matière d'alimentation et de mode de vie, tels qu'un régime alimentaire sain, l'arrêt du tabac et la pratique régulière d'une activité physique.

• If you drink alcohol, ask your doctor for advice. Your doctor may recommend that you do not drink alcohol while you are on irbesartan because it will increase the risk of side-effects, such as feeling dizzy or faint.

• Essayez d'éviter les substituts de sel qui contiennent du potassium. En effet, ces substituts augmentent la quantité de potassium dans le sang, ce qui peut entraîner des problèmes.

• If you are having an operation or dental treatment, tell the person carrying out the treatment that you are taking irbesartan. This is because your blood pressure may drop too low if you are given some anaesthetics.

• Treatment with irbesartan is usually long-term unless you experience an adverse effect. Continue to take the tablets regularly, unless you are advised otherwise by your doctor.

Si vous prenez également de l'hydrochlorothiazide en association avec ce médicament

• Des études ont suggéré que la prise de doses élevées d'hydrochlorothiazide pendant de longues périodes peut augmenter le risque de certains cancers de la peau.

• Informez votre médecin si vous avez déjà été traité pour un cancer de la peau.

• Informez votre médecin de tout grain de beauté nouveau ou modifié ou de toute marque inquiétante sur votre peau.

• Utilisez un écran solaire en cas de forte exposition au soleil. Ne pas utiliser de banc solaire.

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them.
