Olmesartan - an angiotensin receptor blocker

About olmesartan

Olmesartan is an angiotensin receptor blocker. It is also called an angiotensin-II receptor antagonist, or an AIIRA. You will have been prescribed olmesartan because your blood pressure is too high (hypertension). אנשים עם לחץ דם גבוה לעיתים קרובות לא מרגישים רע, אך אם לא מטפלים בו, לחץ דם גבוה יכול להזיק ללב ולפגוע בכלי הדם.

Olmesartan works by blocking the effect of a substance in your body called angiotensin II. Angiotensin II causes your blood vessels to narrow, so by blocking its effect, olmesartan allows your blood vessels to relax and widen. As this happens, the pressure within your blood vessels is reduced.

You may be prescribed olmesartan to take on its own, or alongside other medicines to help your condition. There are a number of combination tablets available which contain olmesartan along with two other medicines to treat high blood pressure, amlodipine and hydrochlorothiazide. These combination tablets are often prescribed to help reduce the total number of tablets that need to be taken each day.

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

• אם את בהריון או מניקה.

• If you have gallbladder problems.

• If you have a problem with your kidneys, particularly if it is a blockage of the artery which supplies blood to your kidneys (a condition called renal artery stenosis).

• אם יש לך בעיות כלשהן עם מסתמי הלב או שריר הלב.

• If you have a problem with the way your liver works.

• אם אתה נוטל תרופות אחרות כלשהן. זה כולל כל תרופה שאתה נוטל שניתן לרכוש ללא מרשם, כמו גם תרופות צמחיות ומשלימות.

• If you have ever had an allergic reaction to a medicine, or if you have had any other type of allergic reaction.

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

• Take olmesartan exactly as your doctor tells you to. It is usual to take one tablet each day. There are several different strengths of tablet available (10 mg, 20 mg and 40 mg). When you first start treatment your doctor may gradually increase the strength of the tablets to suit your condition. 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 olmesartan at the same time of day each day. For most people this will be in the morning. Taking your doses at the same time each day will help you to remember to take olmesartan regularly.

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

• 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.

• Try to keep your regular appointments with your doctor. This is so your progress can be monitored. 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. This is particularly the case when you first start taking olmesartan or if your dose needs increasing.

• If you buy any medicines, check with a pharmacist that they are suitable to take with olmesartan. This is because some anti-inflammatory painkillers (such as aspirin and ibuprofen) can 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 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 olmesartan 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 olmesartan. This is because your blood pressure may drop too low if you are given some anaesthetics.

• Unless you experience an adverse effect, treatment with olmesartan is usually long-term. It's possible that your doctor may advise that you skip a few doses if you have a tummy bug or some other acute illness, but otherwise, please continue to take the tablets regularly.
