Problems solved by technology

[0003] Docetaxel is poorly soluble in water. Even if it is prepared as an injection, it has relatively large toxic and side effects in clinical application and is likely to cause more complications, such as allergic reactions, bone marrow suppression, neurotoxicity, cardiovascular toxicity, hair loss, etc. , while the bioavailability of the drug in vivo is low, and it needs to be used for a long time
Attempts to modify its structure to reduce adverse effects have not made much progress so far
[0004] At present, docetaxel is mainly prepared from polyoxyethylene hydrogenated castor oil and ethanol, etc., which have toxic and side effects on the human body after injection, especially before using docetaxel injection, you must first take anti-allergic drugs or inject anti-allergic Drugs are used to help alleviate the severe allergies and other toxic and side effects caused by the use of docetaxel injection, which often bring pain to patients and directly affect the use of the drug

Abstract

A sub-microemulsion injection of polyene taxol with a certain target performance and low poison is prepared from polyene taxol, the oil for injection, emulsifier, stabilizer, isotonic regulator, pH regulator, and emulsifying aid. Its preparing process is also disclosed.

Description

Technical field: [0001] The invention belongs to the technical field of medicine and relates to a submicroemulsion preparation for injection in the field of drug administration, more specifically a semi-synthetic taxane anticancer drug-docetaxel submicroemulsion injection and a preparation method thereof. Background technique: [0002] Docetaxel (the trade name of the imported product is Taxotere) is an inactive compound extracted from the needles of the European berry yew. This product is a semi-synthetic paclitaxel derivative developed by the French company Aventis. It is a microtubule Depolymerization inhibitor, which acts on the microtubule / tubulin system, arrests cells in G2 and M phases by promoting the assembly of microtubule dimers into microtubules and stabilizing microtubules by preventing the depolymerization process , thereby inhibiting the mitosis and proliferation of cancer cells. Docetaxel is effective for advanced breast cancer, non-small cell lung cancer, o...
