Description

A kind of preparation method for the treatment of the Chinese medicine preparation of chronic heart failure

Technical field

The present invention relates to the field of Chinese medicines.Be specifically related to a kind of preparation method for the treatment of the Chinese medicine preparation of chronic heart failure.

Background technology

Congestive heart failure (CHF) is a kind of syndrome that multiple heart disease finally all will take place, and infers that according to the Framingham research data China has the patients with heart failure more than 10,000,000 approximately, and annual morbidity is about 3～4 ‰, is a kind of common frdquently encountered disease kind.Medicine commonly used clinically at present is diuretic, digitalis type cardiac glycosides and vasodilator, but effect is all comprehensive or existence toxicity, side effect in various degree.The Chinese medicine medicine that is used for anti-chronic heart failure still lacks.Therefore as the market demand, the new Chinese medicine of relevant anti-heart failure will have the wide development prospect, have bigger market, from preventing treatment, considerable economic be arranged.And there is no ideal treatment chronic heart failure oral Chinese medicine (comprising natural drug) listing at present both at home and abroad.

Cornu Cervi side's (in high spirit preparation) is the pure Chinese medicinal preparation of a kind of CHF of treatment.By animal pattern hemodynamics, oxygen-derived free radicals, myocardial cell Na-K-ATP enzymatic activity, Endothelin, nitric oxide (NO) and synthase (NOS) mRNA thereof, Angiotensin II and I receptor mRNA thereof are expressed, the research of neonatal rat myocardial cell cytosolic free calcium and ventricular weight influence, tentatively proved Cornu Cervi side's (in high spirit preparation) have positive inotropic action and may with open L type Ca ²⁺Passage is relevant; Tool antioxidant radical, thereby cardiac function protecting; The endocrine regulation factor delays or blocks effects such as left ventricular remodeling.Cornu Cervi side's (in high spirit preparation) is according to the theory of motherland's medical science " coordinating water and fire, heart kidney is correlated with ", and the academic thought of " kidney is returned in prolonged illness ", " control the heart and why control kidney; " so and control kidney and just controlling the heart, treat congestive heart failure with tonifying kidneys, strengthening heart ruling by law, in clinical practice more than ten years, the chronic heart failure for the treatment of each stage has definite curative effect.

Existing Cornu Cervi side (in high spirit preparation) preparation method adopts decoction and alcohol sedimentation technique to extract active ingredient usually, and the 7th phase P619-621 discloses Cornu Cervi side Study on extraction process result as " Chinese Journal of New Drugs " 2004 the 13rd volumes.

Summary of the invention

Technical problem to be solved by this invention is existing Cornu Cervi side (in high spirit preparation) active ingredient extracting method is improved, a kind of active ingredient content height is provided, the preparation solid preparation is convenient, and the quality of the pharmaceutical preparations is stable, the method for preparing Cornu Cervi square preparation (in high spirit preparation) of determined curative effect.

The preparation method of the Chinese medicine preparation of treatment chronic heart failure disclosed by the invention (the Cornu Cervi square preparation has another name called in high spirit preparation) comprises the following steps:

1, raw material weight percentage ratio prescription

Colla cornus cervi 1%-5% or Cornu Cervi tablet 8%-25%, Herba Epimedii 15%-40%, Fructus Ligustri Lucidi 15%-40%, Fructus Psoraleae 10%-30%, Fructus Corni 8%-25% and Pericarpium Citri Reticulatae 8%-25%;

2, preparation method

Get Colla cornus cervi or Cornu Cervi tablet and pulverize, cross 80 mesh sieves, standby; Getting all the other components in the prescription adds the water that 10-30 doubly measures and decocts 2-3 time for 90 ± 10 ℃, filter, collecting decoction, being concentrated into relative density is 1.04-1.05 (room temperature), the 14000-16000rps high speed centrifugation, getting supernatant concentration to relative density is 1.10-1.14 (90 ℃), spray drying or add a small amount of dextrin spray drying and get extract powder; Above-mentioned harts horn carbon is mixed with extract powder, and adding pharmaceutic adjuvant formulation method is routinely made solid orally ingestible;

Or get in the prescription except that Colla cornus cervi each raw material and add the water that 10-30 doubly measures and decoct 2-3 time filtration, collecting decoction for 90 ± 10 ℃, the 14000-16000rps high speed centrifugation, get supernatant concentration, adding preservative agent, correctives or the Colla cornus cervi after molten are made mixture according to a conventional method.

Each oral formulations of the present invention comprises granule and mixture etc., takes icariin content every day greater than 54mg/g, and psoralen is greater than 42mg/g.

The inventor finds that through repetition test the active ingredient that prior art adopts the water extract-alcohol precipitation method to extract in the Cornu Cervi side can make main active ingredient icariin and psoralen lose more.With Cornu Cervi side's (in high spirit preparation) each component (except the Colla cornus cervi) decocting liquid 90 ℃ the time is example with 70% precipitate with ethanol and high speed centrifugation method of the present invention remove impurity respectively, and the active ingredient result is compared as follows table:

Impurity-removing method icariin content reduces psoralen content and reduces the minimizing of isopsoralen content

(％)?????????????(％)???????????????(％)

70% precipitate with ethanol 14.72 20.79 20.84

High speed centrifugation 9.41 14.17 16.91

The above results shows that decoction and alcohol sedimentation technique makes active ingredient, and particularly the icariin content loss is more, and adopts decocting liquid of the present invention through centrifugal impurity removal process, can effectively reduce the loss of active ingredient, extracts active ingredient to greatest extent.

In addition compared with prior art, the extract of the inventive method acquisition is convenient to the preparation of solid preparation.When extract of the present invention was prepared into solid preparation, usually extracting solution must the spray-dried extract powder that becomes, and granulate, thereby supplementary product consumption in the minimizing preparation reduces clinical taking dose again.If the sample liquid behind the water extract-alcohol precipitation is carried out spray drying, very easily sticking wall is difficult to obtain dried powder, and loss is very big, even obtain powder, because of hygroscopicity is very strong, also is difficult to make granule, makes troubles for the preparation of solid preparation.And the present invention through ultracentrifugal medicinal liquid because to remove impurity comparatively thorough, concentrate, after the spray drying, can obtain dry loose powdered, the back yield rate height of granulating can be suitable for large-scale production.

Chinese medicine preparation of the present invention is specially adapted to treat Chinese medical discrimination and belongs to the chronic heart failure of suffering from a deficiency of the kidney.

Carried out toxicity test with Chinese medicine preparation of the present invention: acute toxicity, the maximum tolerated dose of irritating the stomach mice is crude drug 212g crude drug/kg; Long term toxicity, the high, medium and low dosage group of granule compares with blank group, and the overt toxicity reaction is not seen in administration in continuous six months.Prove that preparation of the present invention is safe in utilization.

By Chinese medical discrimination suffer from a deficiency of the kidney standard and the diagnostic criteria of doctor trained in Western medicine Framingham heart failure, carry out clinical research with the mixture and the granule of extract preparation of the present invention to going into to organize patient, every group 40 example, the result shows:

Preparation of the present invention can significantly improve CHF patient's NYHA cardiac functional grading (obvious effective rate 47%, total effective rate 87%) and the scoring of Lee heart failure, and its curative effect and captopril and digoxin matched group are similar substantially.Simultaneously we can also significantly improve CHF patient's symptom integral of suffering from a deficiency of the kidney, thereby the prompting Chinese medicine especially has one's own knack aspect CHF patient's clinical symptoms improving on treatment CHF really.On the index that ultrasoundcardiogram detected, can see, compare with the digoxin matched group, after taking preparation of the present invention, can significantly improve CHF patient's IVST, PWT, EF, CO, FS, LVMI (P＜0.05), especially the reduction of IVST, PWT, LVMI, in conjunction with the improvement of patient's cardiothoracic ratio, illustrate that we can strengthen myocardium shrinkage function (improving the biological function of cardiac muscle), can suppress or reverse the development of cardiac remodeling again simultaneously.To secular reparation characteristic index, improvement is in various degree arranged all from the hemodynamic index of short-term.This also meets the direction of present heart failure treatment very much: not only improve symptom, improve the quality of living, the more important thing is the mechanism at cardiac remodeling, prevent or delay the development of cardiac remodeling, thereby reduce the mortality rate and the admission rate of heart failure.

Comprehensively above-mentioned, as to adopt the inventive method to prepare Cornu Cervi square preparation, active ingredient content height, preparation is convenient, determined curative effect, this method is particularly suitable for industrialization production.
