إنتاكابون لمرض باركنسون

About entacapone

مرض باركنسون affects the way your brain co-ordinates the movements of your muscles. A number of cells in a small part of your brain, called the substantia nigra, become damaged and die. These brain cells pass messages down nerves in the spinal cord by producing a substance called dopamine and it is these messages which control the muscles of the body. As the cells in the brain are damaged, the amount of dopamine that is produced is reduced. A combination of the reduction of cells and a low level of dopamine in the cells in this part of the brain, causes nerve messages to the muscles to become slowed and abnormal. This produces the main symptoms of Parkinson's disease, which are stiffness, shaking (tremor), and slowness of movement.

You will already be taking a medicine called either co-beneldopa أو co-careldopa. These contain levodopa which helps relieve the symptoms of Parkinson's disease. Levodopa is converted into dopamine and this increases the level of dopamine in your brain.

Entacapone works by increasing the effectiveness of the levodopa you are taking in co-beneldopa or co-careldopa. It is prescribed for people who have had Parkinson's disease for a while and whose symptoms deteriorate between medicine doses. It will be prescribed for you by a specialist doctor.

Before taking entacapone

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 entacapone it is important that your doctor knows:

• إذا كنت حاملاً أو مرضعة.

• If you have heart disease.

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

• If you have been told you have a tumour on your adrenal gland, or if you have ever had a condition affecting your muscles, called rhabdomyolysis, or a reaction to an antipsychotic medicine, called neuroleptic malignant syndrome. These are all very rare conditions.

• إذا كنت تتناول أي أدوية 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.

How to take entacapone

• Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack and any additional information your doctor has given to you. These will give you more information about entacapone, and will also provide you with a full list of side-effects which you could experience from taking it.

• Take the tablets exactly as your doctor tells you to. If you are prescribed Comtess®, take one 200 mg tablet at the same time as your co-careldopa or co-beneldopa tablet or capsule. If you are prescribed Stanek®, Stalevo® or Sastravi® tablets, these are available in different strengths. You will be prescribed the strength of tablet that best suits your condition. Your doctor will tell you how to take the tablets, and the directions will also be on the label of the pack to remind you about what the doctor said to you.

• You can take entacapone either before or after meals.

• When you first start taking entacapone, your doctor may need to adjust the doses of your other medicines. This is to help reduce any side-effects caused by these tablets increasing the effectiveness of your usual dose of levodopa.

تحقيق أقصى استفادة من علاجك

• It is important that you keep your regular appointments with your doctor and clinic. This is so your doctor can check on your progress.

• Entacapone may cause your urine to turn a reddish-brown colour. This is harmless and is nothing to worry about.

• حافظ على نشاطك قدر الإمكان ومارس التمارين بانتظام بقدر ما تستطيع. قد تمشي ببطء أكثر من ذي قبل، لكن المشي اليومي هو تمرين جيد وقد يساعد في تخفيف تصلب العضلات.

• If you are a driver you should tell the DVLA and your insurance company if you have Parkinson's disease.

• If you buy any medicines or vitamins 'over the counter', check with a pharmacist that they are suitable to take with entacapone. You should not take any medicines or vitamin preparations which contain iron at the same time as your entacapone tablets. This is because iron can reduce the amount of entacapone your body absorbs. If you need to take an iron preparation, leave at least two hours between taking entacapone and the iron preparation.

• استمر في تناول الأقراص حتى يخبرك طبيبك بخلاف ذلك. التوقف المفاجئ يمكن أن يسبب مشاكل، وطبيبك سيرغب في تقليل جرعتك تدريجياً إذا كنت بحاجة إلى إيقاف العلاج.

• Sometimes people taking medicines for Parkinson's disease can feel very sleepy during the day. Some people have even fallen asleep suddenly without much warning of being tired. If this happens to you, do not drive and do not use tools or machines, and discuss it with your doctor at your next appointment.

• Some people taking medicines for Parkinson's disease can experience problems with impulsive types of behaviour. If you notice any changes in your behaviour, such as an increased desire to gamble, binge eat, or spend excessively, or an increased sex drive, you must let your doctor know as soon as possible.

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 continue or become troublesome.
