Abstract

The invention relates to an anti-cancer transdermic absorption preparation. The preparation formula is prepared from the following forming components in parts by weight: 0.1 to 10 parts of a primary medicine, 0.1 to 23 parts of a substrate, 0.1 to 15 parts of a humectants, 0.5 to 15 parts of a thickening agent, 0.1 to 10 parts of an emulsifier, 0.1 to 10 parts of a transdermal enhancer, 1 to 10 parts of an inclusion agent, 0 to 2 parts of a preservative, and 45 to 85 parts of a wetting agent, wherein the primary medicine is one or a mixture of two or more components of DDC (diethyldithiocarbamic acid)-Zn, DDC-Cu and DS (disulfiram). The anti-cancer transdermic absorption preparation has the advantages of stable physical property and chemical property, high absorption performance, high medicine controllability, easiness in use and favorability for acceptance by patients, and can be widely applied to anti-cancer treatment of in-patients and out-patients suffering from malignant tumors.

Description

technical field [0001] The invention relates to an anti-cancer percutaneous absorption preparation. Background technique [0002] Malignant tumors are the primary threat to human health. The incidence of malignant tumors in my country is in a period of rapid increase, with an annual incidence of malignant tumors of about 2.6 million and 1.8 million deaths. Malignant tumors have become the number one cause of death among urban and rural residents in China. At present, most malignant tumors are still regarded as "incurable diseases". Treatment methods for malignant tumors include surgery, radiation therapy, and chemotherapy. Traditional chemotherapy drugs have poor selectivity, strong drug resistance and serious adverse reactions. Therefore, it is imminent to develop tumor therapeutic drug preparations with good curative effect and high safety. The purpose of the present invention is to research and develop novel high-efficiency and safe anti-malignant tumor new drugs. ...
