[0003] Codonopsis pilosula has the functions of invigorating the middle and replenishing qi, invigorating the spleen and benefiting the lungs. It is used for symptoms such as weak spleen and lungs, shortness of breath, palpitations, lack of appetite, loose stools, cough due to deficiency, internal heat and quenching thirst. Studies have shown that glycosides in Codonopsis pilosula are mainly The effective parts have the functions of invigorating qi and strengthening the heart, relieving myocardial ischemia, promoting blood circulation and removing blood stasis. Pharmacodynamics and modern clinical studies show that Codonopsis pilosula has good curative effect on heart disease and shock caused by qi deficiency and spleen deficiency; dipyridamole, As an anti-platelet aggregation and coronary artery dilating drug, it is widely used in the treatment of cardiovascular and cerebrovascular diseases. However, it has been found in clinical practice that Codonopsis pilosula preparations are mostly pure Chinese medicine preparations, with slow onset of action, long course of treatment, low bioavailability, and fluctuations in curative effect large; and dipyridamole has certain toxic and side effects, it is not suitable for long-term use, and its clinical application is also limited
Searched the literature and patent databases, but found no preparations that combined the effective parts of Codonopsis pilosula and dipyridamole

Abstract

The invention provides a pharmaceutical composition for treating cardiovascular and cerebrovascular diseases, its preparing process and quality control method, wherein Dipyridamole and total glycosides of codonopsis pilosula are employed in combination to obtain various dose forms of injections and oral administration preparations. The composite preparation is mainly used for treating coronary disease, pulmonary heart disease, cerebral ischemia, nervous prostration, climacteric metancholia, The preparation of the invention has the advantages of high purity, ensured constituents, controllable quality, improved curative effect, wider range of safely, and less fluctuation of treatment effects.

Description

technical field [0001] The invention relates to a pharmaceutical composition for treating cardiovascular and cerebrovascular diseases, a preparation method and a quality control method thereof, and belongs to the technical field of medicines. technical background [0002] At present, about 4 million people die from cardiovascular and cerebrovascular diseases in my country every year, accounting for more than 3 / 5 of the death toll, and it has become the primary factor threatening human health. Although there are a large number of Chinese and Western medicine interviews at present, with the continuous change of disease spectrum and the arrival of aging age, the current medicine continues to show its limitations. Therefore, research and development of medicines for the treatment of cardiovascular and cerebrovascular diseases are always Become the focus and hot spot of people's attention. [0003] Codonopsis pilosula has the functions of invigorating the middle and replenishing...
