Embodiment 1
[0043] 1. Prescription:
[0044]
[0045]
[0046] 2. Preparation method:
[0047] Weigh glycine, add water for injection to prepare 20% glycine solution, and then weigh vitamin B 1 , riboflavin sodium phosphate, and vitamin C were added successively to the glycine solution, stirred and dissolved, and water for injection was added to about 90% of the total liquid volume, and stirred evenly; the pH value was adjusted to the specified range with sodium hydroxide solution, and 0.03% (g / ml) Activated carbon for needles, filled with nitrogen, stirred and adsorbed for 15 minutes, then decarbonized and filtered; the filtrate was supplemented with water for injection to the full amount of the solution, filtered through a 0.22 μm filter, and the filtrate was aseptically filled; the filled medicinal solution was freeze-dried: put When the plate temperature drops to -45°C and the product temperature drops below -36°C, return the shelf to about -30 to -15°C, then cool the shelf to...
