Abstract

The invention discloses a pharmaceutical composition of clonazepam and its medical use. The pharmaceutical composition of clonazepam provided by the invention contains clonazepam and a natural product compound (I) with a novel structure. The composition of clonazepam and compound (I) has obvious anti-inflammatory and antitussive effects, and is better than the independent anti-inflammatory and antitussive effects of clonazepam or compound (I), and can be developed into an anti-inflammatory and antitussive drug, which is different from existing Compared with the technology, it has outstanding substantive characteristics and significant progress.

Description

technical field [0001] The invention belongs to the field of biomedicine and relates to a new application of clonazepam, in particular to a pharmaceutical composition of clonazepam and its application in anti-inflammatory and cough-relieving. Background technique [0002] Clonazepam acts like diazepam and nitrazepam. But the anticonvulsant effect is 5 times stronger than the former two, and the effect is rapid. Similar to the central inhibitory effect of other BDZ drugs, it accelerates the influx of chloride ions in nerve cells, hyperpolarizes the cells, and reduces the excitability of nerve cells. At the same time, it also has a certain effect on glutamic acid decarboxylase, so it has a broad-spectrum antiepileptic effect. This product still has anti-anxiety, hypnotic and central muscle relaxation effects. [0003] So far, there is no report on the correlation between clonazepam and its pharmaceutical composition and anti-inflammatory and cough-relieving. Contents of t...
