Abstract

The invention discloses new application of militarine in preparation of heparin antagonist. The molecular formula of the militarine in the invention is C34H46O17 and the chemical name is bis [4-(beta-D-glucopyranosoxy) benzyl]-2-isobutyl malate. The militarine provided by the invention can be prepared into dosage form suitable for clinical application, mainly including injection, granule, capsule, tablet, powder, pill, drug implants and etc. The effect of antagonize heparin is obvious. The pharmacological effect is similar to or identical with protamine. The invention has the advantage of no adverse reactions to human such as allergy and safety, and can be developed into the substitute of the protamine to be applied in clinic with good application prospect.

Description

technical field [0001] The invention relates to the use of active ingredients of Chinese medicinal materials, in particular to the new application of Militarine in the preparation of heparin antagonistic drugs. Background technique [0002] With the development of surgical technology, the application of heparin in surgery is becoming more and more frequent. It is mainly used clinically for thromboembolic diseases, myocardial infarction, cardiovascular surgery, cardiac catheterization, extracorporeal circulation, hemodialysis, etc., especially in cardiac surgery. Fields are used more generally. At the same time, the use of heparin can easily cause spontaneous bleeding, manifested as various mucosal bleeding, hemarthrosis, and wound bleeding. In severe cases, it will endanger the life of the patient. At this time, heparin antidote must be injected. [0003] Among the existing drugs, protamine is the only antidote to heparin, and since it was discovered in 1937, it has played ...
