Description

Traditional Chinese medicine monomer composition for reducing blood fat, preparation and application
Technical Field
The invention relates to a traditional Chinese medicine monomer composition for reducing blood fat, a preparation and application.
Background
Hyperlipidemia is a common disease in the current society, is manifested by overhigh cholesterol and triglyceride in serum, and can directly cause diseases seriously harming human health, such as atherosclerosis, coronary heart disease, pancreatitis and the like. The incidence of hyperlipidemia increases year by year, and in adults over 30 years of age in the country, the incidence of hyperlipidemia is 10% to 20%.
At present, many blood fat reducing medicines are available in the market, and western medicines are mainly used because of quick response and definite curative effect. Common medicines such as simvastatin can be used for reducing elevated total cholesterol, low density lipoprotein cholesterol, apolipoprotein B and triglyceride, but have obvious side effects and can cause abnormal blood sugar, general muscular soreness, weakness and the like of patients.
According to traditional Chinese medicine, the blood fat is generally considered to be the syndrome of qi stagnation and blood stasis caused by the fact that the blood-fat is increased seriously by phlegm-dampness in vivo and further influences the circulation of qi and blood, so traditional Chinese medicines with the functions of tonifying spleen and removing dampness, and promoting qi and activating blood circulation are selected for treatment. The commonly used lipid-lowering Chinese patent medicines comprise lipid-lowering Ning granules, ginkgo leaf capsules, blood lipid-lowering Kangjiao capsules and the like, and although the lipid-lowering side effect of the Chinese patent medicines is small, the dosage of the Chinese patent medicines is large, and the lipid-lowering effect is not as obvious as that of western medicines.
CN104173495A discloses Jiangzhining granules, which are prepared from the following raw materials in parts by weight: 25-27.5 parts of hawthorn, 1-1.25 parts of prepared fleece-flower root, 1-1.25 parts of cassia seed and 3.25-3.75 parts of lotus leaf. Although the Jiangzhining granules have the effects of expanding coronary vessels, increasing coronary flow, reducing cholesterol absorption, accelerating cholesterol excretion, inhibiting serum cholesterol increase and formation of atherosclerotic plaques, reducing blood fat and cholesterol and the like, the effect of reducing hyperlipidemia (TG) is not obvious, and the Jiangzhining granules need to be taken 3 times a day, 10g each time, the oral dosage is large, the administration is inconvenient, and the granules are easy to get damp.
CN104352594A discloses a Jiangzhining dispersible tablet, which is prepared by extracting hawthorn, prepared fleece flower root, cassia seed and lotus leaf, adding filler, disintegrating agent, flavoring agent, wetting agent, lubricant and glidant. The dispersible tablet is convenient to take, is suitable for the old and patients with swallowing difficulty, but still can not solve the problems of unobvious effect of reducing hyperlipidemia and large oral dosage.
CN108635426A discloses a Jiangzhining Chinese medicinal concentrated watered pill, which is prepared by extracting fructus crataegi, radix Polygoni Multiflori Preparata, semen Cassiae and folium Nelumbinis, and making into watered pill. The watered pill has small volume, is convenient to swallow, is not easy to absorb moisture, but still can not solve the problems of unobvious effect of reducing hyperlipemia and large oral dosage.
In conclusion, although simvastatin, a western lipid-lowering drug, has a good lipid-lowering effect, it has significant side effects and is not suitable for long-term consumption by patients. Although the Chinese patent medicine lipid-lowering Ning granules and the improved preparation thereof have small side effect on treating hyperlipidemia and are suitable for long-term eating, the Chinese patent medicine lipid-lowering Ning granules have the problems of large dosage, unobvious lipid-lowering effect and the like.
