Abstract

The invention discloses a medicine composition with clenbuterol hydrochloride and medical application of the medicine composition. The medicine composition with clenbuterol hydrochloride contains clenbuterol hydrochloride and a natural product compound (I) which has a novel structure; when clenbuterol hydrochloride and the compound (I) work independently, the effects of tranquilizing and allaying excitement can be achieved; when clenbuterol hydrochloride and the compound (I) are combined, the effects of tranquilizing and allaying excitement are more obvious, and the medicine composition can be prepared into a medicine for tranquilizing and allaying excitement; compared with the prior art, the medicine composition disclosed by the invention has outstanding substantive features and a remarkable progress.

Description

technical field [0001] The invention belongs to the field of biomedicine and relates to a new application of clenbuterol hydrochloride, in particular to a pharmaceutical composition of clenbuterol hydrochloride and its medical application. Background technique [0002] Clenbuterol hydrochloride is a potent selective β2 receptor agonist, which can relieve bronchial smooth muscle spasm. Its bronchodilation effect is about 25 times that of orcinalin and 100 times that of albuterol, but it has little effect on the cardiovascular system. . It is characterized by quick onset, long maintenance time, small dose (effective oral dose is 30 μg / time), and mild side effects. Oral absorption is better than albuterol, and its anti-asthma effect is about 170 times stronger than that of terbutaline. It can also enhance bronchial ciliary movement, promote the discharge of sputum, and help improve the anti-asthma effect. It takes 10-20 minutes to take effect after oral administration, reache...
