Problems solved by technology

[0015] The main means to solve the problem of emulsion freezing and thawing is the reasonable selection of emulsifier and oil phase composition
Our idea to solve such problems is to adjust the composition of the oil phase and the composition of the emulsifier with low toxicity. Our test results found that a reasonable selection of the composition of the emulsifier and the oil phase can solve the problem we mentioned in the "Technical Background". Five major problems with existing emulsions

Embodiment 1

[0057] Example 1: Investigate with HS 15 When SPC is used as a compound emulsifier, the effect of different ratios of soybean oil / medium chain oil as oil phase emulsion on particle size before and after freezing and thawing.

[0058] Prescription composition: Coenzyme Q 10 0.25g, soybean lecithin 1.2g, HS 15 0.9g, oil for injection 10g, glycerin 2.2g, and the rest water for injection, a total of 100mL.

[0059] The oil for injection is soybean oil / medium chain oil ratio of 100:0~0:100 (w / w)

[0060] 1. In the preparation tank, inject oil, phospholipid, HS 15 Heat to 50°C, stir until dissolved, add the drug, stir to dissolve;

[0061] 2. In the preparation tank, add glycerin into the water for injection, and stir at 50°C for 5 minutes to completely dissolve it.

[0062] 3. Add 2 to 1 under stirring conditions, and stir at 50°C to obtain colostrum. The resulting liquid is passed through a microfluidizer. The first step is to adjust the homogenization pressure to 4000psi, ...

Abstract

The invention belongs to the medicine area, which involves a multi-emulsifier and a emulsion which be used by the multi-emulsifier and can resist high temperature and low temperature. This multi-emulsifier can combine by two or more then three emulsifiers. When combining, we can use two or more then three emulsifiers at will. The multi-emulsifier includes pharmaceutic adjuvant, oil and water. The emulsion includes drugs, oil phase, multi-emulsifier, the water and so on. The emulsion can be made after combining the oil and the water by isotropic device. The invention has some advantages: 1, the emulsion can resist high temperature and frost thawing. 2, easy to produce the average granularity smaller than the 150nm. 3, obtains the aseptic preparation without the high temperature. 4, produces the emulsion under the low pH value, so expand the application area. 5, increases the chemical stability of the medicine. 6, reduces the irritating quality.

Description

Technical field: [0001] The invention relates to the technical field of medicines, and relates to a composite emulsifier, an emulsion capable of resisting high temperature and low temperature damage prepared by using the compound emulsifier, and a preparation method thereof. Background technique: [0002] Generally speaking, the composition of the emulsion includes "oil phase", "water phase" and "emulsifier". Since the conventional (classic or traditional) emulsion is an unstable system, it is easily affected by external conditions, such as freezing, vibration, etc. Operations such as shaking and high-temperature sterilization will cause particle size changes, or even demulsification and oil separation, resulting in significant changes in product quality, affecting curative effect, unexpected adverse reactions, and even scrapping, resulting in great losses. At present, most of the oil phases for the preparation of emulsions use long-chain fatty acid esters, such as soybean o...
