Problems solved by technology

[0005] Although resveratrol is a promising drug for tumor prevention and treatment, it is poorly absorbed in the body due to its poor solubility in water, instability to light, and limitations of its own physical and chemical properties. The bioavailability is not high, and the clinical effect is not ideal

Description

technical field [0001] The invention relates to an antitumor drug, in particular to an oral multiphase liposome of resveratrol and a preparation method thereof. Background technique [0002] Tumor is a common and frequently-occurring disease, which poses a great threat to people's life and health. It is a research topic that has received more and more attention in the medical field. In many large cities in China, malignant tumors have surpassed cardiovascular and cerebrovascular diseases, ranking first among all causes of death, and in the age group of 35 to 59, tumors have always been the number one killer. In the past, many severe infectious diseases that seriously threatened people's life and health have been controlled, the average life expectancy has been gradually extended, and diagnostic technology has been continuously improved. bit. [0003] At present, tumor treatment includes surgery, radiotherapy and chemotherapy, mainly chemotherapy. The compliance of surgery...
