Problems solved by technology

At present, the clinical application of breviscapine is mainly small injections, but it is found that low doses of breviscapine are not effective, and only large doses of breviscapine can be effective
In clinical application, many small needles need to be sawn open and then poured into normal saline or glucose injection for intravenous infusion, which is not only troublesome to operate, but also more likely to cause secondary pollution
In addition, although the breviscapine freeze-dried preparations that have been on the market have greatly improved their stability, they require high production conditions and are more inconvenient to use. Before use, the ampoule bottle needs to be sawed open and injected with water for injection or physiological Vibrated with saline and then added to normal saline or glucose injection for infusion
[0003] The main component of breviscapine, breviscapine, is unstable and easily deteriorates during storage. Currently, all breviscapine injections used in clinical practice have such problems. Therefore, it is urgent to solve the problem of the stability of breviscapine.

Abstract

The invention discloses a breviscapine injection liquid and its preparing process, wherein each 1000 weight parts of the Breviscapine injection comprises, Breviscapine 0.5-0.9 part, sodium thiosulphate 0.01-2 parts, glucose 50-100 parts, ethylenediaminetetraacetic acid disodium salt 0.01-1 part, adsorbing with activated charcoal 0.1-0.3 part, and balancing water for injection.

Description

(1) Technical field [0001] The invention relates to a breviscapine injection and a preparation method thereof. (2) Background technology [0002] Breviscapus is a total flavonoid extracted from Erigeron breviscapus (Vant) Hand-Mazz plant of Compositae, more than 90% of which is scutellarin, which can expand microvessels, improve microcirculation, improve Myocardial function and blood supply to the heart and brain, reducing blood viscosity, inhibiting platelet aggregation, anti-thrombosis and thrombolysis, and lowering blood lipids. At present, the clinical application of breviscapine is mainly small injections, but it is found in clinical application that low doses of breviscapine are not effective, and only large doses of breviscapine can be effective. In clinical application, many small needles need to be sawn open and then poured into normal saline or glucose injection for intravenous infusion, which is not only troublesome to operate, but also more likely to cause secon...
