Abstract

The invention discloses a bilobalide drop pill. The bilobalide drop pill is prepared from, by weight, 10 parts of bilobalide, 20-40 parts of matrix and 2-6 parts of disintegrating agent. The invention further provides a preparation method of the bilobalide drop pill. Acceleration experiment results show that with the disintegrating agent CMC-Na added into a preparation formula, the bilobalide drop pill is free of obvious change on dissolution rate in vitro and dissolution time limit after 6 months, thereby being high in stability and capable of avoiding ageing effectively.

Description

technical field [0001] The invention relates to a ginkgolide dripping pill and a preparation method thereof, relating to the field of medicine. Background technique [0002] Ginkgolides belong to terpenoids, mainly including ginkgolide A, ginkgolide B, ginkgolide C, ginkgolide M, ginkgolide J and bilobalide, etc., and its chemical structure is shown in the following formula. [0003] [0004] Scientific research shows that ginkgolide is a natural platelet activating factor (PAF) receptor antagonist, which can dilate coronary vessels, improve cerebral circulation, inhibit platelet aggregation, prevent atherosclerosis, antagonize increased vascular permeability, and relieve bronchoconstriction Pharmacological effects such as heart and brain ischemic injury, the central nervous system has a protective effect, anti-aging, anti-shock, anti-allergic, anti-bacterial, anti-inflammatory, anti-tumor, anti-rejection in organ transplantation, and also has effects on liver and kidney ...
