The present invention provides one kind of nanometer solid taxol lipoid particle capable of being used for injection and oral taking and its solid preparation, and features that taxol matter is coated with carrier material and surfactant so as to prepare nanometer solid taxol lipoid particle with small size, high coating rate, high stability, low toxicity and easy surface modification. The nanometer solid taxol lipoid particle has raised targeting effect on cancer cell, enhanced tumor cell killing effect, high curative effect, less toxic side effect, and reduced medicine resistance. The present invention also provides several preparation processes of nanometer solid taxol lipoid particle, and the preparation processes are simple, low in cost and suitable for industrial production. |
