Embodiment 1

[0090] Embodiment 1: Preparation of anti-anemia preparation (amino acid infusion)

[0091] The ingredients shown in the following Table 1 were dissolved in water for injection according to the amounts shown in the table. The solution was sterile filtered and placed in a glass bottle. The bottle was sealed and autoclaved to prepare an anti-anemia preparation (amino acid infusion).

[0092] The pH value of the preparation is 6.6-7.6, and the osmotic pressure ratio is about 2.

[0093] Table 1:

[0094] Element

[0095] The amino acid infusion prepared according to Example 1 is also used as the following purposes: a pharmaceutical preparation for reducing the dosage of erythropoietin (second aspect of the present invention), a pharmaceutical preparation for controlling serum phosphorus levels (third aspect of the present invention) and Pharmaceutical preparations for inhibiting protein catabolism (fourth aspect of the invention).

Embodiment 2

[0096] Example 2. Determination of the ability of pharmaceutical preparations to improve anemia and reduce the dosage of erythropoietin

[0097] Exemplary anti-anemia preparation of the present invention was administered to 18 chronic renal failure patients receiving hemodialysis (HD: 9 cases) or hemodiafiltration (HFD: 9 cases) to examine that the preparation improves anemia and reduces erythropoietin administration Quantitative capacity.

[0098] [method]

[0099] A commercially available amino acid infusion solution "NEOAMYU (registered trademark)" (200 mL formulation, Ajinomoto Pharma Co., Ltd.) prepared according to Example 1 was used.

[0100] In the week before the administration period, the necessary diagnosis, examination and detection were carried out on the first dialysis day (week 1 or week 2). The "NEOAMYU" preparation was continuously administered from 1 week after the diagnosis to 12 weeks and 1 day (the 37th dialysis). Specifically, 1 vial (200 mL) of the pr...

Embodiment 3

[0107] Example 3: Determination of the ability of the above pharmaceutical formulations to control serum phosphorus levels

[0108] The exemplary serum phosphorus control preparation of the present invention was administered to 8 chronic renal failure patients receiving hemodialysis (HD) to examine changes in serum phosphorus levels.

[0109] [method]

[0110] The commercially available amino acid infusion solution "NEOAMYU" (200 mL formulation, Ajinomoto Pharma Co., Ltd.) prepared according to Example 1 was used.

[0111] In the week before the administration period, the necessary diagnosis, examination and detection were carried out on the first dialysis day (week 1 or week 2). The "NEOAMYU" preparation was continuously administered from 1 week after the diagnosis to 12 weeks and 1 day (the 37th dialysis). Specifically, 1 vial (200 mL) of the preparation was infused into the venous side of the dialysis circuit each time of dialysis. The formulation was infused throughout ...

Abstract

An infusion preparation which is to be used in dialyzing a dialysis patient for ameliorating the anemic state by improving nutritional conditions, thus reducing the dosing amount of erythropoietin, controlling the serum phosphorus level to thereby regulate the serum phosphorus level within a definite range and inhibiting the protein catabolism and which contains at least essential amino acids, characterized in that the amino acids are composed of at least L-isoleucine, L-leucine, L-lysine, L-methionine, L-phenylalanine, L-threonine, L-tryptophan, L-valine, L-alanine, L-arginine, L-aspartic acid, L-glutamic acid, L-histidine, L-proline, L-serine, L-tyrosine, glycine and L-cysteine and the ratio of essential amino acids : non-essential amino acids is 2.5 or higher.

Description

[0001] This application is a divisional application based on the application dated June 21, 2007, the application number 200780022937.7, and the title of the invention "transfusion solution for dialysis patients". technical field [0002] The present invention relates to infusion solutions for dialysis patients, and in particular to therapy for anemia in dialysis patients undergoing hemodialysis, hemodiafiltration or other hemodialysis treatments. The present invention also relates to a method for ameliorating anemia in patients with chronic renal failure which entails reducing the amount of erythropoietin (EPO), a hematopoietic hormone administered to patients with chronic renal failure to treat anemia. Background technique [0003] Hemodialysis (HD) is a blood purification technique used to treat patients with chronic renal failure. A challenge with hemodialysis is that it removes not only waste products from the patient's body, but also useful components, such as amino ac...
