Captopril - an ACE inhibitor

About captopril

Captopril belongs to a class of medicines called angiotensin-converting enzyme inhibitors, or ACE inhibitors. It is prescribed for a number of different reasons. You may have been prescribed it to reduce ارتفاع ضغط الدم (فرط ضغط الدم), or to treat فشل القلب, or to protect your heart and blood vessels from further damage following a heart attack, or to protect your kidneys if you have diabetes. Your doctor will tell you why it has been prescribed for you.

ACE inhibitors like captopril prevent your body from creating a hormone known as angiotensin II. They do this by blocking (inhibiting) a chemical called angiotensin-converting enzyme. This widens your blood vessels and helps to reduce the amount of water put back into your blood by your kidneys.

These actions help to decrease blood pressure in people who have blood pressure which is higher than normal. Although people with high blood pressure often do not feel unwell, if left untreated, high blood pressure can harm the heart and damage blood vessels, leading to a نوبة قلبية أو السكتة الدماغية.

Heart failure is a condition where your heart does not work as well as it should. Because of this, there may be too much circulating fluid in your blood vessels. Captopril helps to reduce this. It appears to have a protective effect on the heart and slows the progression of the heart failure. Its protective action also helps to reduce the risk of heart, kidney or blood vessel problems in people who are at risk of these.

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 captopril it is important that your doctor knows:

• إذا كنتِ حاملاً، تحاولين الإنجاب أو تقومين بالرضاعة الطبيعية.

• إذا كنت تواجه مشاكل في طريقة عمل كليتيك.

• إذا كنت تعاني من نقص في السوائل في الجسم (الجفاف) - على سبيل المثال، إذا كنت قد أصبت بالإسهال أو المرض مؤخرًا.

• إذا قيل لك أن لديك تراكمًا للترسبات الدهنية على جدران شرايينك، وهي حالة تُسمى تصلب الشرايين.

• إذا كنت تعاني من نوع معين من ضعف الدورة الدموية يسمى مرض الشرايين المحيطية.

• If you have collagen vascular disease - this includes conditions such as systemic lupus erythematosus (SLE) and scleroderma.

• إذا قيل لك أنك تعاني من مرض عضلة القلب (اعتلال عضلة القلب)، أو تضيق في الوعاء الدموي الرئيسي من قلبك (تضيق الأبهر).

• إذا كنت قد تعرضت في أي وقت مضى لرد فعل حيث يتورم وجهك أو لسانك أو حلقك (وذمة وعائية).

• إذا كنت تتلقى علاجًا لإزالة التحسس للحماية من لسعات النحل والدبابير.

• إذا كنت تتلقى علاج غسيل الكلى، أو علاج لإزالة الكوليسترول من دمك بواسطة جهاز (فصل الدهون منخفضة الكثافة).

• إذا كنت تتناول أي أدوية أخرى. يشمل ذلك أي أدوية تتناولها والتي يمكن شراؤها بدون وصفة طبية، بالإضافة إلى الأدوية العشبية والمكملات الغذائية.

• If you have ever had an allergic or unusual reaction to any other ACE inhibitor (such as lisinopril, ramipril or perindopril), or to any other medicine.

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

• Take captopril exactly as your doctor tells you to. The dose you are prescribed will depend upon your condition - you could be asked to take one, two or three doses each day. The dose will be printed on the label of the pack to remind you what the doctor said to you.

• Your doctor may advise you to take your very first dose at bedtime. This is because you may feel dizzy when you first start taking captopril.

• After this first dose, you can generally take captopril at a time of day you find easy to remember (for most people, this is in the morning). If you are taking more than one dose a day, space your tablets out through the day, but do try to take them at the same times each day. This will help you to avoid missing any doses.

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

• If you forget to take a dose at your usual time, 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.

• حاول الحفاظ على مواعيدك المنتظمة مع طبيبك. هذا لضمان متابعة تقدمك. سيرغب طبيبك في إجراء بعض اختبارات الدم لك من وقت لآخر للتأكد من أن كليتيك تعملان بشكل جيد.

• It is very important that you follow any dietary and lifestyle advice that you are given by your doctor. This may include advice about eating a healthy diet, not smoking, and taking regular exercise.

• If you buy any medicines, check with a pharmacist that they are suitable to take with captopril. This is because some medicines (such as anti-inflammatory painkillers and indigestion remedies) may interfere with your treatment.

• It is likely that your doctor will advise that you do not use salt substitutes while you are taking captopril. These products have a high content of potassium which could be harmful for you.

• If you drink alcohol, ask your doctor for advice about drinking alcohol while you are on captopril. Alcoholic drinks may make you feel light-headed or dizzy, and may not be advisable for you.

• If you have diabetes you may need to check your blood sugar (glucose) more frequently, as captopril may lower the levels of sugar in your blood. Your doctor will advise you about this.

• If you are having an operation or dental treatment, tell the person carrying out the treatment that you are taking captopril. This is because some anaesthetics may cause your blood pressure to drop.

• Treatment with captopril is often long-term unless you experience an adverse effect. Continue to take it unless you are advised otherwise.

• Very rarely, captopril can cause some people's skin to become more sensitive to sunlight than normal. Use a sunscreen in strong sunlight or until you know how your skin reacts. Do not use sunbeds.

إذا كنت تتناول هيدروكلوروثيازيد أيضًا مع هذا الدواء

• أشارت الدراسات إلى أن تناول جرعات أعلى من هيدروكلوروثيازيد لفترات طويلة قد يزيد من خطر الإصابة بأنواع معينة من سرطان الجلد.

• أخبر طبيبك إذا كنت قد تلقيت علاجًا لسرطان الجلد من قبل.

• أخبر طبيبك عن أي شامات جديدة أو متغيرة أو علامات مقلقة على جلدك.

• استخدم واقي الشمس في ضوء الشمس القوي. لا تستخدم أجهزة التسمير.
  

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 captopril. 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.

If you experience any other symptoms which you think may be due to captopril, speak with your doctor or pharmacist for further advice.

• احفظ جميع الأدوية بعيدًا عن متناول ورؤية الأطفال.

• احفظه في مكان بارد وجاف، بعيدًا عن الحرارة المباشرة والضوء.

• If using oral liquid medicine, check how long it will keep once opened - after this time, make sure you have a fresh supply.
