Problems solved by technology

[0019] The object of the present invention is to overcome the inconvenience of clinical intravenous administration of the existing Ginkgo Damole injection (intravenous injection, twice a day) and the slow onset of action of the corresponding unilateral oral preparation, low bioavailability, and poor absorption through the gastrointestinal tract (under strong acid). Biodegradation leads to the destruction of some active ingredients and affects the curative effect, further improving the quality stability and bioavailability of ginkgo damole oral preparations

Abstract

The invention provides a Yinxingdamo oral preparation equivalent to similar intravenous preparation, containing two main drugs: ginkgo leaf extract dipyridamole glucuronide which have the weight ratio of 1:1-4. In addition to the main drugs, the invention also comprises vitamins, glutathione, folic acid and the like as antioxidant, and can further comprise common pharmaceutic adjuvants of binding agent, flow agent, disintegrant, filler and the like. The preparation can be oral liquid preparation, such as tablets, capsules, granules, pills, soft capsules, oral liquid, etc. Compared with the existing ginkgo extract injection, the preparation of the invention has controllable product quality, good stability, long retention period and convenient clinic use.

Description

technical field [0001] The invention relates to an oral solid preparation with ginkgo leaf extract and dipyridamole as main raw materials, in particular to an oral enteric-coated ginkgo damole preparation composition equivalent to similar intravenous preparations and a preparation method thereof. Background technique [0002] Ginkgo biloba extract contains ginkgo total flavonoid glycosides (such as quercetin, kaempferol, isorhamnetin, etc.), ginkgolides (mainly ginkgolides A, B, C and bilobalide), modern pharmacological research It has been shown that ginkgo flavonoid glycosides have a strong antioxidant effect, can remove the remaining free radicals in the body, prevent lipid peroxidation in the body, regulate blood vessel tension, protect capillary permeability, improve microcirculation and blood rheology, and reduce blood viscosity , reduce the damage of harmful substances, protect nerve cells, nourish brain cells and other organs. [0003] Ginkgolide is a platelet activ...
