Abstract

The invention discloses a medicament for preventing in-stent restenosis after coronary stent implantation and a preparation method. The medicament is prepared into 1000 parts from, by weight, 800-1200 parts of tanshinone, 200-300 parts of hirudin, 20-30 parts of camphol and borneol and 6-9 parts of musk ketone. The medicament has the advantages of effective treatment, no toxic and side effects and capabilities of decreasing occurrence rate of in-stent restenosis after coronary stent implantation, obviously improving clinical symptoms of patients and reducing long-term risks of thrombosis of the patients, and is obvious in clinical effect. The medicament provides a new choice for preventing ISR (in-stent restenosis) after coronary stent implantation.

Description

[0001] technical field [0002] The invention relates to a medicine and a preparation method thereof, in particular to a medicine for preventing restenosis after coronary artery stent implantation and a preparation method thereof, belonging to the technical field of medicine. Background technique [0003] With the aggravation of the aging society, the incidence of coronary heart disease in my country has increased significantly; coronary artery stent implantation is an important means of treatment of coronary heart disease, it effectively avoids the elastic recoil of blood vessels and vascular reconstruction after balloon dilatation, and at the same time To a large extent, the shortcomings of coronary artery bypass surgery such as large wound, difficult recovery, and high surgical risk are avoided. However, restenosis after coronary stent implantation (abbreviation: ISR) has also become a problem that cannot be ignored, which limits the use and promotion of this technology. ...
