Embodiment 1
[0023] Example 1: Under clean conditions, take 50g of andrographolide sodium sulfonate, 200g of arginine, 10g of 2-hydroxypropyl β-cyclodextrin, and 2g of sodium bisulfite in an appropriate amount of water for injection at 20°C and stir. Dissolve; adjust the pH value with dilute hydrochloric acid, add 5g activated carbon for needle, stir for 20min, filter and decarburize with 10μm titanium filter rod, after the pH value and content determination pass, filter with 0.45-0.8um microporous membrane, and then 0.2~ Filtration with 0.22um microporous filter membrane; sterilize and remove heat source, and dispense into vials according to the dose so that the unit dose of andrographolide sodium sulfonate in each vial is 50mg, add a rubber stopper, and place the aliquoted vial In a freeze dryer, freeze for 2 hours, make the temperature reach -60℃, make the vacuum degree in the machine 10Pa, slowly increase the temperature, and dry at -20℃, low temperature vacuum for 18 hours, raise the temp...
Embodiment 2
[0024] Example 2: Under clean conditions, respectively take andrographolide sodium sulfonate 25g, sodium chloride 10g, mannitol 10g, 2-hydroxypropyl β-cyclodextrin 5g, L-cysteine hydrochloride 0.1 g Dissolve in an appropriate amount of water for injection at 20°C; adjust pH with gluconic acid and sodium hydroxide, filter with 5μm titanium filter rod, add water for injection, after the pH value and content are determined to be qualified, two ultrafiltration sterilization and removal The heat source is divided into vials according to the dose, so that the unit dose of andrographolide sodium sulfonate in each vial is 25 mg, and a rubber stopper is added. The vials are placed in a freeze dryer and frozen for 2 hours. Bring the temperature to -50°C, make the vacuum inside the machine 10Pa, dry in low-temperature vacuum for 30 hours, raise the temperature to 30°C, dry in vacuum for 10 hours, fill with nitrogen, and press the cover to get it, and control the weight percentage of its mo...
Embodiment 3
[0025] Example 3: Under clean conditions, take 100 g of andrographolide sodium sulfonate, 1000 g of glucose, 100 g of arginine, 20 g of 3-hydroxypropyl β-cyclodextrin, 50 g of sodium gluconate, and 2 g of sodium metabisulfite at 20°C. Dissolve in appropriate amount of water for injection, stir and dissolve; adjust pH with hydrochloric acid and sodium hydroxide, filter and decarbonize with 10μm titanium filter rod, add water for injection, stir well, after the pH value and content are qualified, two ultrafiltration sterilization and heat removal , Divided into vials according to the dose, so that the unit dose of andrographolide sodium sulfonate in each vial is 100mg, add a rubber stopper, put the aliquoted vials in a freeze dryer, freeze for 2 hours, make The temperature reaches -38℃, the vacuum degree inside the machine is 10Pa, and the temperature is increased slowly, low temperature vacuum drying at -38℃~-5℃ for 30 hours, the temperature is raised to 30℃, and vacuum drying for ...
