Aminophylline

About aminophylline

Aminophylline is an oral bronchodilator medicine which is prescribed for people with breathing problems, such as الربو و مرض الانسداد الرئوي المزمن (COPD). It is a medicine that you take by mouth as a tablet. It is also available as an injection, but this is usually given in a hospital environment. Aminophylline is actually a mixture of a medicine called theophylline, and ethylenediamine. The ethylenediamine is used to improve how well the active medicine, theophylline, dissolves.

This medicine works by opening up the air passages in your lungs so that air can flow into your lungs more freely. This makes breathing easier and helps relieve symptoms such as coughing, wheezing and shortness of breath.

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 aminophylline it is important that your doctor or pharmacist knows:

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

• If you have a heart condition or liver problems.

• If you have an overactive thyroid gland gland (hyperthyroidism).

• إذا كنت تعاني من ارتفاع ضغط الدم (فرط ضغط الدم).

• If you have a stomach ulcer.

• If you drink alcohol or smoke.

• إذا كنت تعاني من الصرع.

• If you are currently unwell with a high temperature.

• إذا كنت تعاني من اضطراب دم وراثي نادر يسمى البورفيريا.

• If you have been told you have low levels of potassium in your blood.

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

• إذا كنت قد تعرضت في أي وقت مضى لرد فعل تحسسي تجاه دواء.

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

• Aminophylline is taken twice a day, in the morning and evening. Always try to take your doses 12 hours apart and at the same times each day. For example, at 8 am and 8 pm each day. You can take the tablets before or after meals.

• Swallow the tablets whole with a drink of water. Do not chew, break, or crush them.

• There are two different strengths of tablet available, and you will be asked to take either one or two tablets for each of your doses. Your dose may be adjusted over the first few weeks, depending on the results of some blood tests. The tests allow your doctor to make sure that you have the dose that helps your condition, but avoids any unwanted symptoms.

• Your doctor or pharmacist will tell you what strength of tablet is right for you and how many tablets to take for each dose. Your dose will also be on the label of the pack to remind you.

• If you forget to take a dose but it is still within four hours of the time you should have taken it, take a dose as soon as you remember. If it is more than four hours since you should have taken it, do not take the missed dose but do remember to take your next dose when it is due. Do not take two doses together to make up for a forgotten dose.

• Continue to take aminophylline unless your doctor tells you otherwise. Bronchodilators like aminophylline are usually prescribed long-term.

• Try to keep your regular appointments with your doctor. This is so your doctor can review your condition on a regular basis. Your doctor will want to test your blood from time to time to make sure that you are receiving the correct dose and also to check the levels of potassium in your blood.

• The amount of aminophylline in your blood should be kept within a certain range. It can vary if you are unwell, or if you start or stop smoking, take other medicines, or if you drink more alcohol than usual. This is because these things interfere with the way aminophylline is handled by your body. Some of these things will increase the amount of medicine in your body, leading to side-effects. Others will reduce it, leading to your treatment not being as effective as it should be.

• If at any time you find that your symptoms are getting worse, contact a doctor or nurse for advice straightaway.

• If you want to buy any medicines, check with a pharmacist that they are safe for you to take. Some medicines (including the herbal remedy St John's wort) can affect the levels of aminophylline in your blood and should not be taken alongside it without your doctor knowing.

• Some vaccines, such as the flu vaccine, may also affect aminophylline levels. Make sure you tell your doctor about any vaccinations you have.

• If you are due to have an operation or any dental treatment, tell the person carrying out the treatment which medicines you are taking, as some anaesthetics can interfere with aminophylline.

• Aminophylline can be very toxic in overdose. If you suspect that someone has taken more than they should (and especially if it is a child), go to the accident and emergency department of your local hospital straightaway. Take the container with you, even if it is empty.

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 aminophylline. 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 side-effects continue or become troublesome.
