Problems solved by technology

However, for a long time, the variety of sugar infusion in my country is single, and glucose infusion has always occupied a dominant position.
Although glucose infusion plays an important role in clinical practice, it also has many disadvantages, such as: patients with large fluctuations in blood sugar after infusion, more glucose loss through urine, helpless for patients with insulin resistance, etc.

Embodiment 1

[0022] Example 1 Determination of Invert Sugar Formula for Injection

[0023] 1. Invert sugar formula

[0024] Recipe (specification: 12.5g)

[0025] 1000 bottles

[0026] Fructose 6250g

[0027] Glucose 6250g

[0028] 2. Formula basis

[0029] 1) Determination of dosage form and selection of specifications

[0030] Invert sugar for injection (invert sugar for injection) is a sterile powder injection made by mixing equal amounts of glucose and fructose.

[0031] The specifications of Invert Sugar Injection that have been listed in China are: 250ml: 6.25g fructose and 6.25g glucose. The specification of fructose for injection is 12.5g; 25g. We choose the specification of 12.5g invert sugar for injection per bottle for development.

[0032] 2. Formula screening

[0033] According to the research and analysis of the clinical use of the domestically marketed products Invert Sugar Injection and Fructose for Injection, coupled with the large size of the ...

Embodiment 2

[0034] Example 2 Research on the preparation process of invert sugar for injection

[0035] Research on physical and chemical properties

[0036] For raw materials for immediate aseptic dispensing, the requirement is applicable to the dispensing of pharmaceutical powders. First of all, the physical and chemical properties of the drug should be understood in order to develop a reasonable production process.

[0037] 1. Bulk density

[0038] Fill the invert sugar powder in the measuring cylinder, and vibrate in a certain way to ensure consistent test conditions and good reproducibility. The bulk density can be obtained from the mass and volume of the volume of the micro-powder. We measured the bulk density of invert sugar for injection (batch 040901).

[0039] Method: Put a certain amount of powder of the original medicine into a measuring cylinder, tap it gently several times, and measure its weight and volume.

[0040] Result: bulk density = 0.72 (g / ml)

[0041] Test resu...

Embodiment 3

[0074] Example 3 Test of Influencing Factors of Invert Sugar for Injection

[0075] This test was designed according to the guiding principles of drug stability testing in Appendix XI XC of Part II of the 2000 edition of the Chinese Pharmacopoeia; the test samples met the requirements of the guiding principles. Due to the three batch numbers of this product, the three specifications are obtained by aseptic subpackaging of a batch of raw materials. Therefore, we choose one specification sample of one batch number as a representative to carry out the experiment of influencing factors.

[0076] (1) Sample: batch 031201 (specification: 0.75g) test date: 2003.12.20~2004.1.5; room temperature during test: 15℃~22℃, relative humidity: 55%~80%

[0077] (2) Test items: appearance color, loss on drying, pH, solution clarity and color, pyridine and polymer inspection, related substances, sodium carbonate content, content and labeled content.

[0078] (3) Detection method: carry out acco...

Abstract

An invertose powder injection is prepared from glucose and pectose through preparing aseptic pectose, preparing aseptic glucose, sterilizing tubular bottle, sterilizing butyl rubber plug, mixing aseptic pectose with aseptic glucose to become invertose, loading in aseptic tubular bottle, sealing, and packing.

Description

technical field [0001] The invention relates to an invert sugar powder injection for injection and a preparation method thereof. Background technique [0002] In recent years, with the advancement of clinical medical technology and the continuous improvement of people's living standards, the clinical demand for carbohydrate infusions has grown rapidly. However, for a long time, the variety of sugar infusion in my country is single, and glucose infusion has always occupied a dominant position. Although glucose infusion plays an important role in clinical practice, it also has many disadvantages, such as: patients with large fluctuations in blood sugar after infusion, more glucose loss through urine, and helpless for patients with insulin resistance. At present, a series of sugar infusions such as invert sugar and xylitol have been developed abroad. Among them, invert sugar infusion has been increasingly praised in clinic because of its obvious advantages in sugar infusion. ...
