Valsartan - un bloqueur des récepteurs de l'angiotensine

About valsartan

Valsartan is an angiotensin receptor blocker. It is also called an angiotensin-II receptor antagonist, or an AIIRA. You will have been prescribed valsartan either because your la pression artérielle est trop élevée (hypertension), or because your heart is not working as well as it should (une insuffisance cardiaque), or to protect your heart if you have recently had a heart attack.

Valsartan works by blocking the effect of a chemical called angiotensin II. Angiotensin II causes your blood vessels to narrow, so by blocking its effect valsartan allows your blood vessels to relax and widen. As this happens, the pressure within your blood vessels is reduced and it is easier for your heart to pump blood around your body. Valsartan also helps to protect the heart following a heart attack.

Valsartan 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. Combination brands which contain valsartan alongside other medicines for high blood pressure include Co-Diovan® and Exforge®. Being prescribed a combination brand like these will help to reduce the number of tablets you need to take each day.

One combination brand, called Entresto®, is prescribed for heart failure and contains valsartan with sacubitril.

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 valsartan it is important that your doctor knows:

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

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

• Si vous avez des problèmes avec vos valves cardiaques ou votre muscle cardiaque.

• If you have a problem with the way your liver works, or if you have a condition which blocks the flow of bile from your liver.

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

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

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

• Take valsartan exactly as your doctor tells you to. You may be asked to take valsartan once or twice a day depending on the reason why you are taking it. When you first start treatment, your doctor may gradually increase the strength of your dose to suit your condition. There are several different strengths of tablet/capsule available, so each time you collect a fresh supply, it's a good idea to check the strength on the packet to make sure they are what you are expecting.

• Try to take valsartan at the same time(s) of day each day. Taking your doses at the same times will help you to remember to take valsartan regularly.

• Swallow the tablet/capsule with a drink of water. You can take valsartan either before or after a meal.

• If you forget to take a dose, take it as soon as you remember. If when you remember, it is nearly time for your next dose then take your next dose when it is due but leave out the missed dose. Do not take two doses together to make up for a forgotten dose.

• Essayez de respecter vos rendez-vous réguliers avec votre médecin. Cela permet de suivre vos progrès et de mesurer votre tension artérielle. Votre médecin peut souhaiter que vous fassiez des analyses de sang de temps en temps pour vérifier l'état de vos reins, ainsi que la quantité de potassium dans votre sang.

• If you buy any medicines, check with a pharmacist that they are suitable to take with valsartan. 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 de suivre les conseils diététiques et de mode de vie que votre médecin vous a donnés, tels que manger sainement, ne pas fumer et faire de l'exercice régulièrement.

• If you drink alcohol, ask your doctor for advice. Your doctor may recommend that you do not drink alcohol while you are on valsartan 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 augmenteront la quantité de potassium dans votre sang, ce qui peut poser des problèmes.

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

• Treatment with valsartan is often long-term unless you experience an adverse effect. Continue to take it regularly, unless you are advised otherwise by your doctor.

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

• Des études ont suggéré que prendre des doses plus élevées d'hydrochlorothiazide pendant de longues périodes pourrait augmenter le risque de certains cancers de la peau.

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

• 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 fort ensoleillement. N'utilisez pas de lits de bronzage.

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the most common ones associated with valsartan. You will find a full list in the manufacturer's information leaflet supplied with your medicine. The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.

Si vous ressentez d'autres symptômes que vous pensez être dus aux comprimés, parlez-en à votre médecin ou à votre pharmacien pour obtenir des conseils supplémentaires.

• Gardez tous les médicaments hors de la portée et de la vue des enfants.

• Conserver dans un endroit frais et sec, à l'abri de la chaleur et de la lumière directes.
