Problems solved by technology

Third, aqueous injection preparations have certain limitations in transportation and storage conditions
The above-mentioned patent directly uses sodium hydroxide to adjust the pH value of the solution containing vitamin C, resulting in large fluctuations in the pH value and temperature of the local solution, and sodium hydroxide also produces a large amount of CO with vitamin C. 2 Air bubbles, which accelerate the decomposition of vitamin C, resulting in lower content, increased impurities, and decreased product quality and stability
In addition, the process of waiting for the bubbles to disappear also prolongs the time of the liquid preparation operation

Embodiment 1

[0030] 1. Prescription:

[0031]

[0032]

[0033] Two. Method

[0034] Weigh 120g vitamin C and 90g vitamin C sodium, add to 2500ml water for injection, stir to dissolve; add 300g glycine and 0.5g calcium sodium edetate, stir to dissolve, then add 10g vitamin B1 and 6.355g riboflavin Sodium phosphate (5 g in terms of riboflavin) was stirred and dissolved, and the pH value of the solution was about 4.0; adding activated carbon for needles with a weight to volume ratio of 0.05%, filtered after stirring for 30 minutes, and then added 500 ml of water for injection to 3000 ml; It is filtered through a microporous membrane, filled into 1000 preparation units, and freeze-dried to obtain the product.

[0035] The freeze-drying operation is as follows: the product is put into the freeze-drying box, pre-frozen to below -40°C, crystallized and heated to -12°C, then cooled to below -40°C, heated to 40°C after vacuuming, kept at this temperature for 8 hours, frozen dry end.
