Pharmacology

Amino Acid Keto Analogues tablets are administered for nutrition therapy in chronic kidney disease. Amino Acid Keto Analogues allow the intake of essential amino acids while minimizing the amino-nitrogen intake. The use of Amino Acid Keto Analogues in combination with a very low protein diet allows reducing nitrogen intake while preventing the deleterious consequences of inadequate dietary protein intake and malnutrition.

Dosage & Administration

Adult dose (70 kg body weight): 4 to 8 tablets three times daily during meals. The tablets must not be chewed. Ingestion during meals facilitates proper absorption and the metabolization into the corresponding amino acids.

Pediatric population: No experience has been gained so far with the administration in pediatric patients.

Interaction

Concomitant administration of calcium-containing drugs may cause or aggravate elevated serum calcium levels. Drugs that form hardly soluble compounds with calcium (e.g. tetracyclines, quinolines such as ciprofloxacin and norfloxacin as well as drugs containing iron, fluoride or estramustine) should not be taken at the same time with Amino Acid Keto Analogues to avoid disturbed absorption of the active substances. An interval of at least two hours should elapse between the ingestion of Amino Acid Keto Analogues and these drugs.

Contraindications

Hypersensitivity to the active substances or to any of the excipients, Hypercalcaemia, Disturbed amino acid metabolism.

Side Effects

Hypercalcaemia (Very Rare), If hypercalcaemia occurs, the intake of vitamin D should be reduced. In case of persisting hypercalcaemia, the dose of Amino Acid Keto Analogues as well as the intake of any other calcium sources has to be reduced.

Pregnancy & Lactation

There are no adequate data from the use of Amino Acid Keto Analogues in pregnant women. Animal studies do not indicate direct or indirect harmful effects with respect to pregnancy, embryonal/fetal development, parturition or postnatal development. Caution should be exercised when prescribing to pregnant women. No experience has been made so far with the use during lactation.

Precautions & Warnings

  • The serum calcium level should be monitored regularly
