Irbesartán - un bloqueador del receptor de angiotensina

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 presión arterial alta (hipertensión). 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 estás embarazada, intentando tener un bebé o amamantando.

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

• If you have diabetes mellitus.

• If you have any problems with your heart valves or heart muscle.

• Si está tomando otros medicamentos. Esto incluye cualquier medicamento que esté tomando y que esté disponible para comprar sin receta, así como medicamentos herbales y complementarios.

• Si alguna vez has tenido una reacción alérgica a un medicamento.

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.

• If you forget to take a dose, take it as soon as you remember. If you do not remember until the following day, miss out the forgotten dose. Do not take two doses at the same time to make up for a forgotten dose.

Obteniendo el máximo de tu tratamiento

• 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.

• It is very important that you follow any dietary and lifestyle advice that you may have been given by your doctor, such as eating a healthy diet, not smoking, and taking regular exercise.

• 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.

• Try to avoid salt substitutes which contain potassium. This is because the substitutes will increase the amount of potassium in your blood and this can cause problems.

• 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 también está tomando hidroclorotiazida en combinación con este medicamento

• Los estudios han sugerido que tomar dosis más altas de hidroclorotiazida durante largos períodos de tiempo puede aumentar el riesgo de ciertos tipos de cáncer de piel.

• Informe a su médico si alguna vez ha sido tratado por cáncer de piel.

• Informe a su médico sobre cualquier lunar nuevo o cambiado, o marcas preocupantes en su piel.

• Use a sunscreen in strong sunlight. Do not use sunbeds.
