Problems solved by technology

[0004] Red ginseng extract, Ophiopogon japonicus extract and Schisandra chinensis extract obtained according to the production method in the quality standard of Shengmai injection. Problems such as precipitation and solution turbidity are prone to occur during high temperature sterilization and long-term storage
The current Shengmai injections all use polysorbate 80 as a solubilizer, but polysorbate 80 is prone to rancidity during high-temperature sterilization and long-term storage, resulting in an increase in impurity content; and polysorbate 80 itself has a strong hemolytic effect. Sexuality and allergenicity, which will increase the incidence of adverse reactions of injections
And the products added with polysorbate 80 as a solubilizer will still have a small amount of precipitation and solution turbidity during long-term storage, which increases the risk of clinical medication

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...

Abstract

The invention provides a collateral-generating injection preparation with higher security and a preparation method thereof, the collateral-generating injection preparation is an injection drug mainly prepared by together dissolving a red ginseng extract, a dwarf lilyturf root extract, a fructus schisandrae extract and polyoxyethylene-660-12-hydroxy stearate (solutol-HS15) as a solubilizer into injection water, and the use amount of the used polyoxyethylene-660-12-hydroxy stearate (solutol-HS15) is 0.5g / 100ml. The literature research in the prior art confirms that the security of the polyoxyethylene-660-12-hydroxy stearate (solutol-HS15) used in the preparation is far better than that of polysorbate-80; moreover, safety experiment shows that the security of a collateral-generating injection liquid using the polyoxyethylene-660-12-hydroxy stearate (solutol-HS15) as the solubilizer is obviously better than that of a collateral-generating injection liquid using the polysorbate-80 as a solubilizer.

Description

technical field [0001] The invention relates to the field of pharmaceutical preparations, in particular to a Shengmai injection preparation containing polyethylene glycol lauryl hydroxystearate and a preparation method thereof. Background technique [0002] The standard of Shengmai injection is recorded in the drug standard issued by the Ministry of Health (WS3-B-2865-98, the fifteenth volume of traditional Chinese medicine preparations). . Take 100g of red ginseng, 312g of Ophiopogon japonicus, and 156g of schisandra. For the above three flavors, crush the red ginseng into fine particles, reflux and extract with ethanol for 4 to 5 times, each time for 2 hours, use the thin layer method to control the extraction end point, combine the extracts, refrigerate, filter, and concentrate the filtrate to a thick paste , add water for injection to 400ml, stir well, refrigerate, filter, and the filtrate is used for liquid preparation; Schisandra chinensis is used for steam distillat...
