Problems solved by technology

In the clinical research, it was found that the preparation had relatively serious hemolysis and allergic reactions, and it was necessary to use anti-allergic drugs in advance to prevent it before taking the medicine, which was neither safe nor convenient for clinical use
Studies have shown that Tween 80 may be one of the main reasons for the toxic and side effects of docetaxel preparations[U.Vanhoefer, S.Cao, A.Harstrick, et al. the multidrugresistance protein (MRP), Ann.Oncol.8 (1997) 1221-1228. [11] S.B.Kaye, Taxoids, Eur.J.Cancer 31A (5) (1995) 824-826], histamine release is extremely large

Embodiment 1

[0043] Example 1 Solubilization of Docetaxel by HS15-EPC Mixed Micelles

[0044] HS15 (see structure figure 1 ) and phospholipids to form mixed micelles. The main component of lecithin is phosphatidylcholine (PC, see structure figure 2 ). The two acyl chains of PC increase the hydrophobicity inside the micelle, which can increase the affinity for fat-soluble drugs, and its flexibility is conducive to the accommodation of drug molecules and the formation of a stable combination that is conducive to van der Waals forces. In addition, the intervention of PC makes the structure of mixed micelles slightly expanded, and the volume is larger than that of simple micelles, which can accommodate more fat-soluble drug molecules [Chen Jing, Tu Xide, Huang Feiyun, etc. New excipients for injections- -- Bile salt / lecithin mixed micelle system. Advances in Pharmacy, 2001, 25(4): 227-230].

Abstract

The present invention relates to a mixed micelle medicine preparation and a preparation method, which is prepared by the combination of various kinds of surface acting agents. The mixed micelle consists of the polyethylene glycol-12-hydroxy stearate and the other surface acting agents of one kind or various kinds. The other surface acting agents comprise phospholipid, VE Macrogol succinate, Macrogol-VE-carbonate and Macrogol-VE-succinate. In addition, the mixed micelle also comprises drugs, solvent, a stabilizer with or without other components and a PH conditioner. The amount of the polyethylene glycol-12-hydroxy stearate in the prescription is 4 percentage to 40 percentage, W / V: the amount of the phospholipid is 0 percentage to 30 percentage, W / V: the amount of the activator is 0 percentage to 30 percentage, W / V: the amount of the drug is 0.001 percentage to 10 percentage, W / V: the amount of the solvent is 0 percentage to 90 percentage, W / V. The medicine comprises the hydrophobicitydrug and the lip solubility drug, but the medicine is not restricted by the both kinds of drugs. The present invention has the following advantages. Firstly, the preparation has good dilution stability, which can improve the defect in the present preparation and can meet the demanding for clinical drug administration. Secondly, the toxicity is low and the chemical stability is excellent.

Description

Technical field: [0001] The invention relates to the technical field of medicine, in particular it is a mixed micelle pharmaceutical preparation prepared by using multiple surfactants in combination and a preparation method thereof. technical background: [0002] Among the medicinal active substances, there are a large part of fat-soluble drugs that are insoluble in water, which brings a lot of inconvenience to the preparation process and clinical application, and also brings many adverse effects on the efficacy of the drug, and it is even difficult to prepare a reasonable preparation. In order to solve such problems, one of the more commonly used methods is to solubilize drugs with surfactants. [0003] Surfactant refers to a substance that can significantly reduce the surface tension of a liquid at a relatively low concentration. The structural characteristics of surfactant molecules are composed of polar hydrophilic groups and non-polar hydrophobic groups. Therefore, su...
