Problems solved by technology

[0005] Due to the shortcomings of the extraction process and the characteristics of the Chinese medicinal materials, the quality of the above-mentioned ginkgo leaf extracts is difficult to be strictly controlled; in addition, the quality of the original medicinal materials in different origins and different picking seasons is quite different, resulting in the active ingredient content of preparations, especially injection preparations, Clarity and color are not stable enough
Extracts of raw medicinal materials contain unpredictable impurities, which are likely to cause adverse reactions, and there are problems of heavy metals and pesticide residues
The disadvantages of unstable content of active ingredients and the presence of impurities lead to hidden dangers of drug safety in its preparations, especially injections

Abstract

The invention relates to pharmaceutical composition and relevant preparation containing active constituents of ligustrazine and ginkgo leaves, wherein the compound preparation can act on human body by employing the synergism between the two constituents, and is effective in activating blood circulation, removing stasis, resisting platelet conglomeration, expanding blood vessel, improving microcirculation, thus can be used for preparing medicament for treating ischemic cardiovascular and cerebrovascular diseases.

Description

technical field [0001] The invention belongs to the technical field of pharmacy, and in particular relates to a pharmaceutical composition containing effective ingredients of ligustrazine and ginkgo biloba and a preparation thereof. technical background [0002] Ligustrazine is an alkaloid monomer extracted from the traditional Chinese medicine Ligusticum chuanxiong, and its hydrochloride and phosphate are commonly used. Ligustrazine hydrochloride and ligustrazine phosphate are white or off-white crystalline powders, which can dilate blood vessels, increase coronary blood flow, cerebral blood flow and improve microcirculation, increase myocardial contractility, and prevent and treat ischemia, hypoxia and reperfusion. Pharmacological effects such as cell damage. Ligustrazine is rapidly absorbed and excreted, and can pass through the blood-cerebrospinal fluid barrier. Clinically used for ischemic cerebrovascular diseases (such as cerebral insufficiency, cerebral thrombosis, ...
