Valsartan - um bloqueador do receptor de angiotensina

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 pressão arterial muito alta (hipertensão), or because your heart is not working as well as it should (insuficiência cardíaca), 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.

Before taking valsartan

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:

• Se você está grávida, tentando ter um bebê ou amamentando.

• If you have a problem with your kidneys, particularly if it is a blockage of the artery which supplies blood to your kidneys.

• Se você tiver algum problema com suas válvulas cardíacas ou músculo cardíaco.

• 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.

• Se você estiver tomando outros medicamentos. Isso inclui quaisquer medicamentos que você esteja tomando e que estejam disponíveis para compra sem receita médica, bem como medicamentos fitoterápicos e complementares.

• Se você já teve uma reação alérgica a um medicamento.

How to take valsartan

• 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.

• Se você esquecer de tomar uma dose, tome-a assim que se lembrar. Se, ao se lembrar, já estiver quase na hora da próxima dose, tome a próxima dose no horário habitual, mas pule a dose esquecida. Não tome duas doses juntas para compensar uma dose esquecida.

Obtendo o máximo do seu tratamento

• 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 how much potassium is in your blood.

• 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.

• É muito importante que você siga quaisquer orientações dietéticas e de estilo de vida que seu médico possa ter lhe dado, como manter uma alimentação saudável, não fumar e praticar exercícios regularmente.

• 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.

• Procure evitar substitutos de sal que contenham potássio. Isso porque os substitutos podem aumentar a quantidade de potássio no seu sangue, o que pode causar problemas.

• 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.

Se você também estiver tomando hidroclorotiazida em combinação com este medicamento

• Estudos sugerem que tomar doses mais altas de hidroclorotiazida por longos períodos de tempo pode aumentar o risco de certos tipos de câncer de pele.

• Informe o seu médico se você já foi tratado para câncer de pele antes.

• Informe seu médico sobre qualquer nova pinta ou alteração em pintas existentes, ou marcas preocupantes na sua pele.

• Use protetor solar sob luz solar intensa. Não use camas de bronzeamento.
