Embodiment 1
[0026] Example 1: Under clean conditions, take ethylenediamine diacetamidoacetic acid 200g, sorbitol 40g, sodium sulfate 2g, arginine 25g, 2-hydroxypropyl β-cyclodextrin 5g, sodium bisulfite 0.12 g in an appropriate amount of water for injection at 20°C, stir and dissolve; use gluconic acid and sodium hydroxide to adjust the acidity to about pH=4.5, add 0.1g of activated carbon for needles, stir for 20min, filter and decarbonize with a 10μm titanium filter rod, pH value and content After the determination is qualified, filter with a 0.45-0.8um microporous membrane, and then filter with a 0.2um-0.22um microporous membrane; sterilize and remove pyrogens, and pack them into vials according to the dose, so that the diacetylamine in each vial The unit dose of ethylenediamine acetate is 0.2g, with a rubber stopper, put the subpackaged vials in a freeze dryer, freeze for 2 hours, make the temperature reach -40°C, and make the vacuum degree in the machine 10Pa. Dry for 18 hours, raise...
Embodiment 2
[0027] Example 2: Under clean conditions, take ethylenediamine diacetamidoacetic acid 400g, sodium chloride 10g, lysine 50g, 2-hydroxypropyl β-cyclodextrin 5g, nicotinamide 25g, L-cysteine Amino acid hydrochloride 0.12g is dissolved in an appropriate amount of water for injection at 20°C, stirred and dissolved; the acidity is adjusted to about pH=4 with glucuronic acid and sodium hydroxide, filtered through a 5μm titanium filter rod, and water for injection is added to wait for the pH value and content After the determination is qualified, two times of ultrafiltration to sterilize, remove the pyrogen, and pack in the vials according to the dose, so that the unit dose of ethylenediamine diacetamidoacetic acid in each vial is 0.4g, add a rubber stopper, and pack the vials , put it in a freeze dryer, freeze for 2 hours, make the temperature reach -40°C, make the vacuum inside the machine 10Pa, dry in low temperature vacuum for 30 hours, raise the temperature to 10°C, dry in vacuum...
Embodiment 3
[0028] Example 3: Under clean conditions, 600g of ethylenediamine diacetate, 10g of glucose, 10g of disodium hydrogen phosphate, 15g of arginine, 5g of 2-hydroxypropyl β-cyclodextrin, 20g of nicotinamide, Dissolve 0.12g of sodium metabisulfite in an appropriate amount of water for injection at 20°C; use hydrochloric acid and sodium hydroxide to adjust the acidity to about pH=4.5, filter through a 10μm titanium filter rod for decarburization, add water for injection, stir well, and measure the pH value and content After passing the test, two times of ultrafiltration to sterilize, remove pyrogens, and pack in vials according to dosage, so that the unit dose of ethylenediamine diacetamidoacetic acid in each vial is 0.6g, add a rubber stopper, and pack the vials , put it in a freeze dryer, freeze for 2 hours, make the temperature reach -40°C, make the vacuum inside the machine 10Pa, dry in low temperature vacuum for 30 hours, raise the temperature to 10°C, dry in vacuum for 10 hour...
