Problems solved by technology

But there are many problems, such as coenzyme Q published in Chinese Pharmacopoeia 10 The injection is dissolved with a large dose of Tween 80, which causes a lot of allergies and hemolysis clinically.
At the same time, since coenzyme Q 10 Unstable to light, heat and water, so Q 10 The injection solution is very unstable and easily decomposed
And it can only be injected intramuscularly. Although the microemulsion technology has improved the above-mentioned technology, it is still difficult to apply it because of the addition of some surfactants as creaming agents, and the safety of injection of many excipients has not been determined.
[0004] coenzyme Q 10 Due to its important physiological functions, it has become a research hotspot in the medical and pharmaceutical circles. There are a large number of published literature and patents, among which coenzyme Q 10 There are many utility patents, and the following patents are related to this patent after retrieval: ①World patent WO20041080208, which uses emulsification technology, but belongs to the field of food, and mainly discloses the formula and process of preparing an oral milk powder and organic co-composition , no coenzyme Q was involved 10 Submicroemulsion Injection Technology
② Chinese patent CN200410022007 describes a stable coenzyme Q 10 The injection preparation method mainly uses the surfactant Tween 80 to help dissolve, and at the same time adds Ve and other inhibitors, but the water cannot be completely isolated, and the stability will be affected: the surfactant will also increase the occurrence of side effects
③ Chinese patent CN02808179 describes a 10 The microemulsion preconcentrate and microemulsion are mainly prepared by surfactant Tween 80 and triglyceride, which are suitable for oral administration and not suitable for injection
In the literature Int.J.Pharm 2004 Apr 1:273(1-2):63-73 author PalamkuluA describes a coenzyme Q 10 The self-emulsifying drug delivery system mainly uses the oil phase mixed with various surfactants to make oral preparations. After oral administration, it is mixed with gastric juice to form a microemulsion to promote coenzyme Q 10 Absorption, which is quite different from this patent, the above patents and contents do not involve coenzyme Q 10 Submicroemulsion injection and preparation method thereof

Abstract

The invention relates to a method for preparing coenzyme Q10 sub micro-emulsion injection, wherein said agent can treat cardiovascular disease, hepatitis, etc, while it can be injected or orally taken. And it comprises coenzyme Q10, soya oil, lecithin, glycerin, and injection water at 0.1-2:7-30:0.5-3:2-2.5:0-1:65-89; it uses high-speed mixer or ultrasonic vibration to form initial emulsion, via high-pressure mixer to prepare coenzyme Q10 sub micro-emulsion. Said agent is water-packing-oil sub micro emulsion, which packs coenzyme in water-packing-oil micro oil to reduce excited reaction and side effect, with target function.
