Abstract

The invention relates to a medicine for treating asthma and a preparation method thereof. The medicine takes pentacyclic triterpenoid, particularly friedelin, corosolic acid or a mixture thereof and an optional second active ingredient as active ingredients for treating asthma, can obviously inhibit the attack of the asthma and inhibit the secretion of inflammatory factors, and has certain activity of inhibiting the contraction of tracheal smooth muscle, so that the medicine can be used for preventing and treating asthma.

Description

technical field [0001] The invention belongs to the field of medicines, and in particular relates to a medicine for treating asthma and a preparation method thereof. Background technique [0002] Asthma (Asthma), also known as bronchial asthma, is an airway disease that is composed of eosinophils, mast cells, T lymphocytes, neutrophils, smooth muscle cells, airway epithelial cells and other cells and cell components. Chronic inflammatory disease. The clinical symptoms mainly include recurrent wheezing, shortness of breath, chest tightness, cough and other symptoms. According to a survey data in 2017, there are nearly 30 million asthma patients in my country, and the trend is increasing year by year, especially in adolescents and children, the most obvious increase in the prevalence of asthma. [0003] Asthma is mainly affected by genetic factors and environmental factors, but the specific pathogenesis is still unclear. The proposed pathological mechanism of asthma mainly i...
