Abstract

The invention discloses a drug composition of bisoprolol fumarate and a pharmaceutical application thereof. The drug composition of the bisoprolol fumarate contains the bisoprolol fumarate and a novel-structured natural product compound (I) separated from dried loquat leaves, wherein a compound of the bisoprolol fumarate and the compound (I) has obvious anti-inflammation and cough-reliving effects which is better than the independent anti-inflammation and cough-reliving effects of the bisoprolol fumarate or the compound (I), and can be developed into an anti-inflammation and cough-reliving drug. Compared with the prior art, the drug composition has prominent substantive features and remarkable progress.

Description

technical field [0001] The invention belongs to the field of biomedicine and relates to a new application of bisoprolol fumarate, in particular to a pharmaceutical composition of bisoprolol fumarate and its application in anti-inflammatory and cough-relieving. Background technique [0002] Bisoprolol fumarate is a β-receptor blocker, which has a high affinity for β1-receptors of bronchial and vascular smooth muscle, thereby dilating blood vessels and lowering blood pressure. It is suitable for hypertension, coronary heart disease, and moderate to severe chronic stable heart failure. [0003] Bisoprolol fumarate is a highly selective β1-adrenoceptor antagonist without intrinsic sympathomimetic and membrane stabilizing activity. Bisoprolol fumarate has high affinity to β1-receptors of bronchial and vascular smooth muscle, but only low affinity to β2-receptors of bronchial and vascular smooth muscle and regulation of metabolism. Therefore, bisoprolol fumarate generally does n...
