Abstract

The present invention is applicable to the technical field of pharmaceutical preparations, and provides a cabazitaxel protein nano-injection and a preparation method thereof. The cabazitaxel protein nano-injection comprises the following raw materials in parts by weight: 50-150 parts of cabazitaxel; protein carrier 400-4000 parts of materials; 50-300 parts of protein nano-modified materials; 12-100 parts of freeze-drying protective agent. In the present invention, cabazitaxel is encapsulated in a spherical or ellipsoidal nanometer composed of a protein carrier material and a protein nano-modified material or attached to the surface of the nanometer, and subjected to freeze-drying treatment with a freeze-drying protective agent to obtain the cabazitaxel protein nanometer. The injection has a good sustained-release effect and a high anti-tumor effect, which effectively avoids the hypersensitivity caused by the use of co-solvents such as surfactants, reduces the toxicity of the preparation, improves bioavailability, and reduces the dosage. Prolong the administration time.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical preparations, and in particular relates to a cabazitaxel protein nano-injection and a preparation method thereof. Background technique [0002] Cabazitaxel belongs to the class of taxane antineoplastic drugs, which is a semi-synthetic paclitaxel derivative derived from the compound extracted from the needles of taxus. Its mechanism of action is similar to other taxane drugs, by promoting the assembly of microtubule dimers At the same time, it prevents the depolymerization process and stabilizes the microtubules, inhibits further cell division, thereby inhibiting the mitosis and proliferation of cancer cells. [0003] The currently marketed product is cabazitaxel injection. In order to increase the solubility of cabazitaxel and the stability of the preparation, a large amount of surfactants such as polysorbate 80 and dehydrated ethanol are added to the injection prescription as co-solvents. ...
