Embodiment 1
[0025] Example 1 (the dosage of HS15 is 0.5g / 100ml)
[0026] Red Ginseng 100g
[0027] Ophiopogon japonicus 312g
[0028] Schisandra 156g
[0029] HS15 5g
[0030] For the above three medicinal materials, cut red ginseng into thin slices or crush them, impregnate them with more than 90% ethanol and extract them under reflux for 4 to 5 times, each time for 2 hours, combine the extracts, refrigerate, filter, and recover the ethanol until each 1ml contains 0.3~ 0.4g, add an appropriate amount of activated carbon, stir, adjust the pH value of the filtrate to near neutral, let it stand still, concentrate the filtrate to a thick paste, add water for injection to 200ml, stir well, refrigerate, filter, add an appropriate amount of activated carbon to boil, filter, filtrate For liquid preparation; Schisandra chinensis, crush if necessary, collect 150ml of distillate by steam distillation, refrigerate, for liquid preparation, decoct the dregs with water twice, 40 minutes each time,...
Embodiment 1
[0037] Embodiment 1 and comparative example 1 safety contrast
[0038] Safety judgment basis: according to different prescription products of the present invention ( Embodiment 1 and comparative example 1 ) and the difference and degree of immune response produced by different prescription products and the difference and degree of hemolysis in animals to compare their safety.
[0039] Results: Both the immune response and the hemolytic reaction produced in Example 1 were lower than those in Control Example 1.
[0040] Conclusion: The safety of the Shengmai injection preparation of the present invention (using polyethylene glycol lauryl hydroxystearate as a solubilizer) is obviously better than that of the current commercially available Shengmai drug injection preparation (using polysorbate 80 as a solubilizer). ). It can be expected that in the future clinical application, the occurrence of adverse reactions such as allergy and hemolysis caused by polysorbate 80 can be gr...
