World Science and Technology-Modernization of Traditional Chinese Medicine 2015;(6):1290-1294
Ligustrazine is one of the active ingredients of chuanxiong. Modern medical research indicated that ligustrazine had the effect of improving microcirculation, anti-inflammatory, anti-fibrosis, which showed the potential function of ligustrazine in the prevention and treatment of postoperative abdominal adhesions. The basic theory of traditional Chinese medicine (TCM) also believed that ligustrazine had the unique double effect of regulating both qi and blood. Therefore, ligustrazin had broad research and application prospects in the prevention and treatment of postoperative abdominal adhesions. This article reviewed studies of ligustrazine in the prevention and treatment of postoperative abdominal adhesions in recent years from four aspects, which were theoretical basis, clinical application, mechanism research and pharmaceutical dosage forms. It identified the research status and advantages of ligustrazine in the prevention and treatment of postoperative abdominal adhesions. It also pointed out shortages in the clinical application, such as unstandardized medication, small sample size study and etc. There were insufficient deep and clear studies in the research of mechanism. In the aspect of pharmaceutical dosage forms, the thinking should be expanded with innovation. It will provide basis and direction for research and application in the future, in order to further elucidate mechanisms in the prevention and treatment of postoperative abdominal adhesions as well as provide theory basis, research thinking and methods for the real display of advantages in TCM.
