Example Embodiment

[0057] Example 1

[0058] Raw material weight ratio:

[0059] Ginseng total saponins extract 50g Epimedium total flavonoids extract 40g Hydroxypropyl-β-cyclodextrin 800g

[0060] Preparation:

[0061] a. Dissolve hydroxypropyl-β-cyclodextrin with 4000ml of water to make a 20% solution. Add 750ml (5.33%) of the total flavonoids extract of Epimedium to heat to dissolve, and slowly add hydroxypropyl-β-ring in portions In the dextrin solution, keep the temperature at 80°C±1°C, dynamically stir and clathrate for 3 hours, add 100ml (50%) of the total ginsenoside extract to water to dissolve it by heating, add it to the clathrate solution, and continue to clathrate for 1 hour;

[0062] b. Add water to adjust the total amount of the solution to 6000ml, adjust the pH to 7.5 with 10% sodium hydroxide solution, add 24 grams of activated carbon (that is, containing 0.4% activated carbon), boil for 10 minutes, filter with a clear plate while it is hot, and filter out the activated carbon , Then fi...

Abstract

The invention provides a traditional Chinese medicinal composition freeze-drying injection and a preparation method thereof. The traditional Chinese medicament freeze-drying injection is prepared from raw materials comprising ginseng and epimedium herb by extraction and refinement of a modern process and then by a freeze-drying process. The traditional Chinese medicament preparation meets technical requirements of the State Food and Drug Administration (SFDA) on the traditional Chinese medicament injection and is clinically applied to treatment on amyotrophy and myasthenia gravis caused by diseases such as motor neuron diseases (amyotrophic lateral sclerosis, progressive spinal muscular atrophy, progressive bulbar palsy and primary lateral sclerosis), progressive myodystrophy, congenital myopathy and the like. The traditional Chinese medicament freeze-drying injection is administrated clinically through intravenous, intramuscular or acupoint injection.

Description

technical field [0001] The invention relates to a traditional Chinese medicine freeze-dried injection and a preparation method thereof, belonging to the technical field of pharmaceutical preparations. Background technique [0002] Traditional Chinese medicine injection is the inheritance and development of traditional ethnic medicine, and it is a high-quality product in the "quintessence of China"; its safety and effectiveness have been proven in clinical practice; however, the potential safety hazard of water injection is much greater than that of powder injection. As the storage time prolongs and the environment changes, large insoluble particles will appear in the aqueous injection. Once these particles enter the blood vessels of the human body, serious adverse reactions are likely to occur. Aqueous injections are also susceptible to contamination during storage and transportation. The freeze-dried powder is solid, and there will be no problem of large particle precipita...
