Description

A drug drop pill for treating cardiovascular disease

technical field

The invention relates to a medicinal dripping pill for treating cardiovascular diseases, which belongs to the field of traditional Chinese medicines.

Background technique

With the improvement of living standards, the aging of the world's population and the rejuvenation of the disease population, cardiovascular and cerebrovascular patients are increasing year by year, and have become the second largest disease that endangers human health. Angina pectoris is a clinical syndrome caused by temporary myocardial ischemia and hypoxia, with episodic chest pain or chest discomfort as the main manifestation. Coronary heart disease angina pectoris refers to angina pectoris caused by myocardial ischemia and hypoxia due to coronary artery sclerosis or spasm, accounting for about 90% of angina pectoris patients.

The current methods of treating angina pectoris mainly focus on dilating blood vessels, reducing blood viscosity, anti-platelet aggregation, and anti-coagulation. The traditional western medicines used are nitrates, nitrites, β-receptor blockers, calcium antagonists, etc., but all of them have relatively large toxic and side effects, and should not be taken for a long time. great effect. For example, after taking nitroglycerin, sometimes there will be dizziness, throbbing pain in the head, rapid heartbeat, and even fainting [see the new pharmacology [14th edition] page 264], and it has been found to cause severe hypotension in recent years [see Chinese Journal of Modern Medicine 1997; 7(4): 42; Shaanxi Medical Journal 1996; 25(5): 315], prone to tolerance [see Southern Nursing Journal 1996; 3(5): 7～9] and other issues, which hinder its use in clinical application.

Although there are many Chinese patent medicines for treating angina pectoris, pills, powders, creams, pills, and decoctions have long been ancient and are rarely used by modern people. At present, there are ordinary compound Danshen tablets and capsules on the market, but the production process of ordinary tablets and capsules is relatively backward, the content of active ingredients is low, and there is no quality control standard. They need to be taken orally and absorbed through the gastrointestinal tract, and the first-pass effect occurs in the liver. After being absorbed into the blood, the bioavailability is low and the absorption is slow, so it is not suitable for the first aid needs of patients with angina pectoris.

Compound Chuanxiong Dropping Pills is a drug for the treatment of coronary heart disease with fast onset and good curative effect, and is very popular among patients in clinic. The present inventor has carried out in-depth research from the extraction technology aspect, has completed the present invention.
