Embodiment 1
[0022] Example 1: Under clean conditions, take 20g of diisopropylamine dichloroacetate, 19g of sodium gluconate, 200g of arginine, 10g of 2-hydroxypropyl β-cyclodextrin, and 0.5g of sodium bisulfite at 20°C Add an appropriate amount of water for injection, stir to dissolve; adjust the pH value with dilute hydrochloric acid, add 1g of activated carbon for needles, stir for 20min, filter and decarbonize with a 10μm titanium filter rod, after the pH value and content are qualified, use a 0.45-0.8um microporous filter membrane Filter, and then filter with a 0.2-0.22um microporous membrane; sterilize, remove pyrogens, and pack in vials according to dosage, so that the unit dose of diisopropylamine dichloroacetate in each vial is 20 mg, and the unit dose of sodium gluconate 19mg, add rubber stopper, place the subpackaged vial in a lyophilizer, freeze for 2 hours, make the temperature reach -45°C, make the vacuum degree in the machine 10Pa, dry in low temperature vacuum for 18 hours, ...
Embodiment 2
[0023] Example 2: Under clean conditions, take 40g of diisopropylamine dichloroacetate, 38g of sodium gluconate, 10g of sodium chloride, 10g of lysine, 5g of 2-hydroxypropyl β-cyclodextrin, 20g of nicotinamide, Add 0.1g of L-cysteine hydrochloride in an appropriate amount of water for injection at 20°C, stir and dissolve; adjust the pH with glucuronic acid and sodium hydroxide, filter through a 5μm titanium filter rod, add water for injection, and wait for the pH value and content to be determined After passing the test, two times of ultrafiltration to sterilize, remove pyrogens, and divide into vials according to the dose, so that the unit dose of diisopropylamine dichloroacetate in each vial is 40 mg, and the unit dose of sodium gluconate is 38 mg, and add a rubber stopper. , Place the subpackaged vials in a lyophilizer, freeze for 2 hours, make the temperature reach -50°C, make the vacuum degree in the machine 10Pa, dry in vacuum at low temperature for 30 hours, raise the ...
Embodiment 3
[0024] Example 3: Under clean conditions, take 60g of diisopropylamine dichloroacetate, 57g of sodium gluconate, 1000g of glucose, 100g of arginine, 20g of 3-hydroxypropyl β-cyclodextrin, 50g of sodium pantothenate, and sodium metabisulfite Dissolve 2 g in an appropriate amount of water for injection at 20°C; adjust the pH with hydrochloric acid and sodium hydroxide, filter through a 10 μm titanium filter rod, add water for injection, stir well, and after the pH value and content are qualified, sterilize by ultrafiltration twice, Remove the pyrogen, pack in vials according to the dose, make the unit dose of diisopropylamine dichloroacetate in each vial be 60 mg, and the unit dose of sodium gluconate be 57 mg, add rubber stoppers, put the vials that have been divided into In the freeze dryer, freeze for 2 hours, make the temperature reach -40°C, make the vacuum degree inside the machine 10Pa, dry in low temperature vacuum for 30 hours, raise the temperature to 30°C, dry in vacuu...
