Problems solved by technology

[0010] The currently published methods for preparing micellar systems have their own advantages and disadvantages, but they generally have low drug loading, complex production processes, and many intermediate links, which are not conducive to large-scale control of industrial production, and the excipients contain phospholipids and other properties. Unstable substances, so the stability is poor, which is not conducive to various problems of sterilization
At the same time, the above methods are mostly suitable for drugs that are only insoluble in water, and for drugs that are insoluble in both water and most organic solvents, it is difficult to make micellar solutions or precursor micellar preparations using the above methods

Embodiment approach

[0026] The present invention is further discussed below in conjunction with embodiment:

[0027] Surfactant polysorbate prepares the embodiment of albendazole precursor micelle:

Embodiment 1

[0028] Example 1: Add 1 g of albendazole (principal drug) to 3 g of lactic acid (solvent), fully stir and dissolve at 50 ° C, then add 1 g of Tween-80 (surfactant) to the previous solution, and mix well to form a transparent liquid Shaped albendazole precursor micelle is a new precursor micelle preparation; the new precursor micelle preparation contains 20% of the main drug, 60% of the solvent content, and 20% of the surfactant content; the new precursor The hydration encapsulation rate of the micellar preparation is 80%, and the particle size is 30-450nm.

Embodiment 2

[0029] Embodiment 2: The preparation method is the same as in Example 1, except that the addition of Tween-80 (surfactant) is 2g, and the addition of Albendazole (main ingredient) and lactic acid (solvent) is all the same as in Example 1; In the obtained transparent liquid albendazole precursor micelle, that is, the novel precursor micelle preparation, the main drug content is about 17%, the solvent content is 50%, and the surfactant content is 33%; the novel precursor The encapsulation efficiency of the micelle preparation was 81% after hydration, and the particle size was 20nm to 400nm.

Abstract

The present invention is one new kind of precursor micelle preparation and its production process and usage. The precursor micelle preparation contains main medicine, solvent, surfactant and supplementary material. The production process includes the steps of dissolving the main medicine in solvent, adding surfactant, and mixing to obtain the precursor micelle preparation. Or, the production process includes the steps of dissolving the main medicine in volatile solvent, adding the surfactant into the solution, and volatizing the solvent to obtain the precursor micelle preparation. The usage of the precursor micelle preparation includes diluting in water for hydration, dissolving carrier material and forming micelle automatically. The precursor micelle preparation of the present invention may be applied widely in agriculture, chemical industry, food and other fields.

Description

technical field [0001] The present invention relates to a novel precursor micelle preparation and its preparation method and use method. It is a novel precursor micelle preparation and its production method and use method. It is especially suitable for drugs that are difficult to dissolve in water and most organic solvents. in vivo absorption and efficacy. Background technique [0002] Some drugs that are insoluble in both water and most organic solvents cause difficulties in the preparation process and clinical application of the drugs, and the single dosage form of these drugs also affects the absorption and efficacy of the drugs in the body. To solve the above problems, we invented a new precursor micellar preparation. [0003] Surfactants are typical amphiphilic molecules, which contain lipophilic hydrocarbon chains and hydrophilic functional groups. If a very small amount of surfactant is added to pure water, it will be adsorbed on the surface of the water phase and a...
