Problems solved by technology

[0004] 1. Curcumin liposomes, Li Liping et al. (Research on the preparation process of curcumin liposomes [J]. Journal of Fourth Military Medical University, 2009, 30 (24): 3166-3168), which injected curcumin lipids with ethanol The average encapsulation efficiency of the plastid is only 46.69%, the encapsulation efficiency is low, and it takes a long time to operate steps such as water bath and rotary evaporation, so it is difficult to realize industrial production;
[0005] 2. Sustained-release microspheres, Lin Mei et al. (Preparation and sustained-release performance of curcumin microspheres [J]. Journal of Fujian Medical University, 2010, 44(3): 178-181), the encapsulation efficiency can only reach 15.6 %-62.4%, poor operability;
[0006] 3. Curcumin nanoparticles, Liu Zhanjun et al. (Preparation and drug release performance of curcumin nanoparticles [J]. Chinese Materia Medica, 2009.32(2): 277-279), the drug loading capacity of curcumin nanoparticles is 0.3 g / L The encapsulation efficiency was up to 91.6%, but with the increase of curcumin drug concentration, the encapsulation efficiency was only 79.4% when the drug loading was 0.6 g / L, and the encapsulation efficiency decreased with the increase of drug concentration, Poor druggability, water bath, magnetic stirring, and dialysis are used in the preparation process, the operation time is too long, and the operation steps are complicated;
[0008] Due to the various deficiencies in the above-mentioned injections, so far no curcumin compound injections have been used in clinical practice.

Abstract

The invention relates to the technical field of medicine, and particularly relates to a curcumin compound injection and an intravenous injection preparation thereof. The curcumin compound injection mainly comprises a curcumin compound, a solvent for injection and a small amount of pH regulator. The curcumin compound intravenous injection preparation is used only by mixing the curcumin compound injection and an emulsifier in a volume ratio of (1:5)-(1:250). After the curcumin compound injection and the emulsifier are mixed, the drug loading rate of the curcumin compound in the intravenous injection preparation is up to 1.5 mg / ml, and no crystal is separated out within 18 hours. The curcumin compound injection provided by the invention has a simple and safe preparation method and good stability, and is convenient for storage and transportation. The curcumin compound intravenous injection preparation has good stability due to the use of the emulsifier as a carrier solvent, and has no toxic and adverse effects. The invention solves the problem that the curcumin compound can not be prepared into the intravenous injection preparation and applied in clinics for a long period of time.

Description

technical field [0001] The invention relates to the technical field of medicine, and relates to a curcumin compound injection solution and an intravenous injection thereof. Background technique [0002] Curcumin compounds are chemical components extracted from the rhizomes of some plants in Zingiberaceae and Araceae, including curcumin, demethoxycurcumin, bisdemethoxycurcumin, etc. Curcumin compounds are insoluble in water and ether, but soluble in methanol, ethanol, acetone, ethyl acetate, glacial acetic acid and lye. It is unstable in light and alkaline environment, and should be kept away from light. [0003] The main pharmacological effects of curcumin compounds are anti-oxidation, anti-inflammation, anti-coagulation, lipid-lowering, anti-atherosclerosis, anti-aging, eliminating free radicals and inhibiting tumor growth, etc., and has liver protection effect. However, due to the poor water solubility of curcumin, the bioavailability is low when taken orally, and the st...
