Embodiment 1
[0032] The formula used in this example is:
[0033] Low molecular weight chondroitin sulfate sodium salt with an average molecular weight of 8,000 3,000g
[0034] Mannitol for injection 1,500g
[0035] Water for injection up to 300,000mL
[0036] The preparation steps used in this embodiment are as follows:
[0037] (1) Weigh the formulated amount of low molecular weight chondroitin sulfate sodium salt and mannitol for injection;
[0038] (2) Dissolve in water for injection;
[0039] (3) Add 0.2% activated carbon, boil for 5 minutes, filter and decarburize;
[0040] (4) Filter the solution obtained in step (4) with a 0.22μm microporous membrane;
[0041] (5) Fill 3mL filtrate in a 10mL control glass bottle;
[0042](6) Freeze-drying, sealing, labeling, packaging, quality inspection, and obtaining freeze-dried powder for injection of low molecular weight chondroitin sulfate sodium salt.
Embodiment 2
[0044] The formula used in this example is:
[0045] Medium molecular weight chondroitin sulfate potassium salt with an average molecular weight of 12,000 3,000g
[0046] Sodium Chloride for Injection 2,700g
[0047] Water for injection up to 300,000mL
[0048] The method of this embodiment is basically the same as the method of embodiment 1, except that in step (1), the formula amount of the medium molecular weight chondroitin sulfate potassium salt and the filler sodium chloride are weighed; finally, the medium molecular weight chondroitin sulfate potassium salt is obtained Lyophilized powder for intravenous injection of salt.
Embodiment 3
[0050] The formula used in this example is:
[0051] Low molecular weight chondroitin sulfate calcium salt with an average molecular weight of 6,000 1,000 g
[0052] The preparation steps used in this embodiment are as follows:
[0053] (1) Dispense 500 mg of low molecular weight chondroitin sulfate calcium salt into 10 mL control glass bottles;
[0054] (2) Sealing, labeling, packaging, quality inspection, and obtaining low-molecular-weight chondroitin sulfate calcium salt injection powder for injection.
