Problems solved by technology

One is that the pain-inducing side effects of tanshinone IIA drugs during injection are not considered, which makes it unbearable for patients, and some patients even refuse to use this drug
The second is that they did not pay attention to the targeting of the treatment site of the drug. Sodium tanshinone IIA sulfonate and sodium tanshinone phosphate are mainly used to treat cardiovascular and cerebrovascular diseases, lung cancer, liver cancer, and leukemia, and should be concentrated in the circulatory system, lungs, and liver. department
The tanshinone IIA drug injection prepared by the prior art adopts the activated carbon process, so there are heavy metal ions and tiny carbon particles adsorbed by the activated carbon caused by the pollution of the activated carbon, which are harmful to the human body

Abstract

The invention relates to an albumin nanosphere composition medicament, method for preparing and use, wherein the composition medicament is prepared from the following raw materials (by weight ratio): albumin 1000-2000, tanshinone IIA salt 20-200, vegetable oil 200000-400000, PEG6000 100-200, N-(2-mercapto propionyl)-glycine 20-100, and lysine hydrochloride 20-30.

Description

technical field [0001] The invention relates to an albumin nanosphere combination medicine and its preparation and use method. Background technique [0002] The existing tanshinone IIA drug preparations are conventional injections with antioxidant added, conventional cyclodextrin containing preparations, conventional freeze-dried powders and solid dispersions. One is that the pain-inducing side effects of tanshinone IIA drugs during injection are not considered, which makes it unbearable for patients, and some patients even refuse to use this drug. The second is that they did not pay attention to the targeting of the treatment site of the drug. Sodium tanshinone IIA sulfonate and sodium tanshinone phosphate are mainly used to treat cardiovascular and cerebrovascular diseases, lung cancer, liver cancer, and leukemia, and should be concentrated in the circulatory system, lungs, and liver. department. In the prior art, although liposome preparations and even nanoparticle lipo...
