Ketosteril®

Trusted brand, proven results. Rely on the original

Ketosteril 

delays the start of dialysis

Very low protein diet supplemented with ketoanalogues (sVLPD), compared to a low protein diet (LPD) or dialysis, is safe and effective in delaying dialysis in CKD patients

يحتوي كيتوستيريل® على نظائر كيتونية من الأحماض الأمينية الأساسية لتقليل الحمل النيتروجيني مع توفير الأحماض الأمينية الأساسية في سياق نظام غذائي منخفض أو منخفض جدًا في البروتين. يمكن تحويل الأحماض الأمينية من  النظائر كيتونية من دون المساهمة في الحمل النيتروجيني. وبالتالي، فإن إعطاء نظائر كيتونية من الأحماض الأمينية يحل الصراع بين الحد الأدنى من متطلبات البروتين وتقييد البروتين لعلاج مرض الكلى المزمن. ونتيجة لذلك، فإن النظام الغذائي المقيد بالبروتين والمكمل بنظائر كيتونية يقلل من اليوريميا. كما أنه يخفف من العديد من الأمراض المصاحبة لمرض الكلى المزمن، على سبيل المثال فرط فوسفات الدم، وانخفاض حساسية الأنسولين أو الحماض الأيضي. وبالتالي، فإنه يؤخر بدء غسيل الكلى لمدة عام تقريبًا. وهذا هدف علاجي مهم للمريض الفرد وطبيب الكلى المسؤول عنه. يمكن تقليل عبء المرض بسبب علاج غسيل الكلى وكذلك تكاليف الرعاية الصحية الإجمالية إلى حد كبير

Details

​Ketosteril® is part of the conservative treatment of patients with Chronic Kidney Disease. Ketosteril® contains amino acids, partly in form of their corresponding-ketoanalogues, essential for patients with Chronic Kidney Disease. In combination with a protein-restricted diet Ketosteril® is an excellent tool to alleviate Chronic kidney disease symptoms in the predialysis period.

Other ingredients

Corn starch, crospovidone, povidone (K-value 29-32), talc, highly dispersed silicon dioxide, magnesium stearate, macrogol 6000, colouring agents E 104, E 171, alkaline polymethacrylate, glycerol triacetate.

Indications

Prevention and therapy of damages due to faulty or deficient protein metabolism in chronic renal insufficiency in connection with limited protein in food of 40 g per day (for adults) and less; i.e. generally in patients with a glomerular filtration rate (GFR) below 25 ml/min.

Contra-indications

Hypercalcaemia, disturbed amino acid metabolism. In case of hereditary phenylketonurie it has to be taken into account that this product contains phenylalanine.

Precautions for use and warnings

No experience has been made so far with the application in pregnancy and paediatrics.
Ketosteril® should be taken during meals to allow proper absorption and metabolism into the corresponding amino acids. The serum calcium level should be monitored regularly. An adequate supply of calories should be ensured.

Undesirable effects

Hypercalcaemia may develop. In this case, it is recommended to decrease vitamin D intake. If the hypercalcaemia persists, reduce the dosage of Ketosteril® as well as any other source of calcium.

Dosage instructions

In general, unless prescribed otherwise, four to eight tablets are swallowed whole three times daily during meals. This dosage applies to adults (70 kg bodyweight) (1 tablet/5 kg body weight/day).

Instructions for use/handling/storage

Do not use Ketosteril® after expiry date! Keep out of the reach of children! Do not store above 25°C. Protect from moisture.

Interaction with other drugs

Simultaneous administration of medicinal products that contain calcium (e.g. acetolyte) may trigger, or worsen, a pathological increase in the serum calcium level.

As the uraemic symptoms improve under therapy with Ketosteril® tablets, the dose of aluminium hydroxide administered should be reduced, as appropriate. The patient should be monitored for reduced levels of serum phosphate.
In order not to interfere with absorption, an appropriate interval should be observed between administration of Ketosteril® tablets and medicinal products which form poorly soluble compounds with calcium (e.g. tetracyclines, quinolones such as ciprofloxacin and norfloxacin, preparations that contain iron, fluoride and estramustin). An interval of at least 2 hours should be observed between the intake of Ketosteril® tablets and such preparations. If administration of Ketosteril® tablets leads to increased blood levels of calcium, the sensitivity to medicinal products which increase heart action (cardiac glycosides) and thus also the risk of cardiac arrhythmia is increased.

  • Reduction of uraemic symptoms, which are largely due to an accumulation of degradation products of the protein metabolism
  • Preservation of the residual renal function and therefore slowing down the rate of progression of the disease and delaying the onset of dialysis
  • Preservation of the nutritional status, despite the marked reduction of the daily protein intake
  • Improvement of metabolic complications due to renal insufficiency (e.g. proteinuria)
