JP4894219B2 - Peripheral parenteral nutrition infusion containing vitamin B group - Google Patents

Description

  The present invention relates to a nutritional infusion preparation for peripheral veins containing amino acids, carbohydrates, electrolytes and vitamin B group which are water-soluble vitamins. More specifically, in patients who are undernourished or especially elderly, who are likely to be deficient in dietary intake and have a latent or manifested vitamin deficiency, the nutrients such as glucose or amino acids to be administered It can cause serious side effects based on metabolic disorders of nutrients by coexisting vitamins and carbohydrates that affect glucose metabolism, and by coexisting vitamins and amino acids that affect amino acid metabolism. The present invention relates to highly safe infusion preparations, particularly peripheral parenteral nutrition infusion preparations.

  Necessary nutrients such as amino acids, carbohydrates, and electrolytes are intravenously administered to patients who cannot orally lack nutrition. In this case, since sugars (especially reducing sugars) and amino acids cause Maillard reaction, they are separated and stored in a multi-chamber container, and each chamber is communicated before use and mixed. Administered to patients. On the other hand, when a multi-chamber container is not used, the Maillard reaction is suppressed if the infusion pH is kept extremely acidic. However, in such preparations, there are various practical applications such as vascular pain, vascular damage and acidosis at the time of infusion. Problems occur. Therefore, recently, nutritional infusion preparations using a multi-chamber container have been widely used as high-calorie infusion preparations and peripheral parenteral nutrition infusion preparations.

  In the case of high-calorie infusion therapy, since the infusion therapy often lasts for a long time, these nutrients are added at the time of use so as not to cause deficiency of vitamins or trace elements. Recently, a preparation containing vitamins in a high-calorie infusion containing sugar, amino acid, and electrolyte has been developed, and consideration has been given to prevent the occurrence of vitamin deficiency during high-calorie infusion (see Non-Patent Document 1).

On the other hand, in the case of peripheral parenteral nutrition infusion, the administration period is as short as about 2 weeks or less, and it is premised on switching to other nutrition supplements such as oral diets early or in combination, so partial energy supplementation It was considered that there was no need for vitamins.
Recently, however, it has been pointed out that vitamins should be taken into account in peripheral parenteral nutrition infusion therapy, and recently, patients with peripheral parenteral nutrition infusion also have a potential deficiency of vitamins, resulting in high calorie content. There are some reports that vitamins should be considered not only at the time of infusion, but also at the time of peripheral nutrient infusion (see Non-Patent Documents 2 and 3).
For these reasons, even in peripheral parenteral nutrition infusion preparations, vitamin B1 alone may cause serious side effects such as acidosis at the time of deficiency. A patent for a peripheral parenteral nutritional infusion formulation containing B1 has been filed (see Patent Document 1).

However, in patients who are undernourished, especially in elderly patients who need nutritional fluid therapy, there is no single vitamin deficiency. It is easy to make shortage in the short term.
On the other hand, vitamin B group is indispensable in order for glucose and amino acids in nutritional infusions to be supplemented to be metabolized, and if these are deficient or deficient, serious metabolic disorders are known to occur. (See Non-Patent Document 4).
That is, it is known that when vitamin B1 is deficient in glucose metabolism, the citric acid cycle from pyruvic acid via acetyl-CoA is impaired, resulting in acidosis. In the case of B6 deficiency, various amino acid metabolisms such as transamination, deamination and decarboxylation are affected, and skin symptoms such as stomatitis, stomatitis, seborrheic dermatitis, peripheral neuritis, convulsions, anemia, etc. Involved in the manifestation of symptoms. Furthermore, vitamin B group is also known to have an interaction. For example, for the metabolism of homocysteine, which is considered to be one of the factors of arteriosclerosis, vitamin B2, B6, B12 and folic acid are metabolized in cooperation. It is controlled and single vitamin replacement therapy is not expected to be effective. In addition to this, it is known that many elderly people are in a state of potential vitamin B12 deficiency, and symptoms of reduced concentration and depression are observed even with mild B12 deficiency.

That is, vitamins are essential nutrients for the metabolic use of glucose and amino acids, which are the main components of nutritional infusions, and vitamin B groups are easily deficient particularly in elderly and undernutrition patients. When a nutritional infusion containing only vitamin B1 shown in Fig. 1 is administered, there is a problem that vitamin B groups other than vitamin B1 are insufficient.
Accordingly, in the medical field, it is desired to provide a peripheral parenteral nutritional infusion preparation in which an amount of vitamin B group necessary for the metabolic use of glucose and amino acids is blended.

However, vitamin B12, niacin, folic acid, and the like are added to a drug solution containing a carbohydrate (hereinafter referred to as a carbohydrate solution) or a drug solution containing an amino acid (hereinafter referred to as an amino acid solution) in a general multi-chamber container type peripheral vein infusion preparation. When added, there was a problem that a stable preparation could not be obtained for reasons such as decomposition.
In the peripheral parenteral nutritional infusion preparation described in Patent Document 1, the combination of vitamin B12 and folic acid is limited only to the case where it is combined with the third chamber drug solution isolated from the carbohydrate solution and amino acid solution. . Also in the high-calorie infusion preparation described in Non-Patent Document 1, cyanocobalamin (vitamin B12) and folic acid are blended in a third-chamber drug solution that is isolated from the saccharide solution and amino acid solution. Vitamin B12 can be mixed with vitamin B1, niacin, ascorbic acid, etc. during infusion, niacin can be decomposed under strong acid or alkaline conditions, folic acid is a divalent metal cation, riboflavin phosphate, ascorbine It seems to be a contrivance to solve the problems such as mixing changes with acids and turbidity in the acidic region.

It is characterized by containing. These vitamin B groups contained in the peripheral parenteral nutrition infusion preparation of the present invention may instead use derivatives, precursors or compounds having the same action and effect.

  Vitamin B1, which is a coenzyme of pyruvate dehydrogenase, directly controls the metabolism of glucose, and when vitamin B1 is deficient, glucose utilization does not proceed smoothly, causing side effects such as acidosis. Vitamin B1 needs to be supplemented in an appropriate amount according to the amount of glucose supplemented. Vitamin B2 that acts as a coenzyme FAD and FMN that are essential for energy metabolism of both glucose and amino acids, and NIA and NADP that act as coenzymes for dehydrogenation, depending on the amount of energy supplement, are appropriate amounts.

Thereby, even when it is administered to a patient who is deficient in vitamin B6, the metabolic utilization of amino acids is good.
Furthermore, it is preferable to add vitamins (folic acid, vitamin B12, etc.) having an interaction with these vitamins to the peripheral parenteral nutrition infusion preparation of the present invention. This makes it possible to obtain a preparation that hardly causes metabolic abnormalities such as hyperhomocysteinemia.

<Composition of vitamin B group and electrolyte>
In the peripheral parenteral nutrition infusion preparation of the present invention, the vitamin B group and the electrolyte are usually distributed and mixed into a carbohydrate solution or an amino acid solution as follows.
First, since vitamin B1 is stable in the acidic region, it is added to the sugar liquid side. Moreover, since vitamin B1 becomes unstable when sulfite is present, it is desirable that the saccharide solution does not contain sulfite.
Vitamin B12 reacts with vitamin B1 and changes its composition, so it is added to the amino acid solution.

Folic acid reacts with divalent electrolytes (calcium, magnesium, etc.) and vitamin B2 to cause blending changes, so that it is preferably blended separately. Therefore, when producing a two-chamber container preparation that does not require a third chamber, vitamin B2 and a divalent electrolyte coexist. However, since vitamin B2 usually reacts with calcium at a pH of 5 or more to produce an insoluble salt, it is preferable to mix vitamin B2 and a divalent electrolyte (calcium, magnesium, etc.) in an acidic saccharide solution. .
Furthermore, it is preferable to contain citric acid as a pH adjusting agent in the sugar solution. By adding citric acid, it is possible to prevent the formation of insoluble salts due to the reaction between vitamin B2 and calcium even in a chemical solution having a pH of about 6.

After filtering both liquids obtained above according to a conventional method, 700 mL of sugar / electrolyte / vitamin solution and 300 mL of amino acid / electrolyte / vitamin solution were each divided by a polypropylene (polyolefin) two-chamber bag (easy peel seal). Each chamber of the bag having two chambers) was filled, and the amino acid solution was purged with nitrogen, sealed, and then autoclaved according to a conventional method to obtain a peripheral parenteral nutrition infusion preparation.
The pH after mixing both solutions (sugar solution and amino acid solution) was about 7.

(Test Example 1)
The results of measuring the content of the blended vitamins after storing the preparation of Example 1 at room temperature for 2 months and 8 months are shown in Table 1.

  All of the blended vitamins showed a content of 90% or more even at room temperature of 8 months, and were found to be preparations capable of supplementing the intended vitamin.

(Test Example 2)
Table 2 shows the stability of vitamins when the liquidity was changed with the composition of Example 1. When the pH of the sugar solution is 4 or less, the stability of vitamin B2 is lowered, and when the pH is made 6 or more, the stability of vitamin B1 is lowered, and the pH of the amino acid solution is 6 or less or 8 or more. When it was made, the stability of folic acid decreased. From these results, it was considered that the pH of the carbohydrate solution was 4 to 6 and the pH of the amino acid solution was 6 to 8 in favor of the stability of each vitamin.

  The present invention is a peripheral parenteral nutritional infusion preparation containing a carbohydrate, an amino acid, an electrolyte, and a vitamin and housed in a multi-chamber container. It can be used for medical use as a safe infusion preparation that does not cause serious side effects. In particular, it can be suitably used for medical purposes as a nutritional infusion for peripheral veins in the case of a vitamin deficiency or a potential vitamin deficiency in an elderly person or a patient in an undernutrition state.
