Abstract

The invention provides a medicinal composition containing bilobalide B. The medicinal composition contains bilobalide B and a vitamin K antagonist. The invention further provides a preparation method and an application of the medicinal composition. The experiment proves that bilobalide B can obviously promote the anti-platelet aggregation function of warfarin, also can eliminate / reduce the natural drug resistance of a patient generated due to only use of warfarin, and enhance the affinity between the liver receptor of a patient and warfarin, and bilobalide B and warfarin have the synergistic interaction. The medicinal composition is novel in formula, simple in components, definite in action mechanism and obvious in curative effect, tolerance is difficultly generated, and industrial production can be realized.

Description

technical field [0001] The invention relates to a pharmaceutical composition containing ginkgolide B. Background technique [0002] Warfarin is an indirect-acting coumarin-based oral anticoagulant, a dicoumarin derivative with a chemical structure of 3-(a-phenylacetone)-4-hydroxycoumarin. It has no anticoagulant effect in the test tube, that is, it does not participate in in vitro anticoagulant blood, and exerts anticoagulant effect by inhibiting the synthesis of coagulation factors II, VII, IX, and X in liver cells by inhibiting vitamin K. The carboxylase in liver microsomes can convert the glutamic acid of the above coagulation factors into γ-carboxyglutamic acid, which can then combine with calcium ions to exert its coagulation activity. The function of this drug is to inhibit carboxylase, and it has no direct antagonism effect on the above-mentioned factors that have been synthesized. It must wait for these factors to be relatively exhausted in the body before it can ex...
