Abstract

The invention belongs to the field of medicine and particularly relates to in-situ gel for subcutaneous injection for treating breast cancer and its pharmaceutical use. The active ingredient of the in-situ gel for subcutaneous injection is astragalin or a composition of astragalin and laurolitsine in the weight ratio of the astragalin to laurolitsine is 63 to 69: 19. The excipients of the in-situgel for subcutaneous injection comprise soy lecithin, medium chain triglyceride and 90% ethanol. The in-situ gel for subcutaneous injection for treating breast cancer exerts a sustained release effectby a gel drug reservoir formed by subcutaneous injection, has a good therapeutic effect on estrogen-dependent breast cancer and can reduce toxic or side effects caused by systemic administration suchas oral administration or intravenous injection.

Description

technical field [0001] The invention belongs to the field of medicine, and in particular relates to an in-situ gel for subcutaneous injection for treating breast cancer and its application. Background technique [0002] Cancer is a major disease that seriously threatens human life. According to the epidemiological statistics from 2016 to 2017, the top five cancers in male cancers in my country are non-small cell lung cancer, gastric cancer / cardia cancer, colorectal cancer, esophageal cancer, and small cell lung cancer. The top five cancers in women are breast cancer, colorectal cancer, small cell lung cancer, cervical cancer, and gastric / cardiac cancer. In other words, breast cancer is the most important malignant tumor that threatens women's life and health. [0003] Breast cancer is mainly produced by malignant changes in the mammary ductal epithelium. The main clinical manifestations are mammary gland swelling and pain, mass, lymph node enlargement under the armpit and...
