Description
Technical field
The invention belongs to the field of Chinese medicines, particularly relate to a kind of pharmaceutical composition for the treatment of essential hypertension and preparation method thereof.
Background technology
By the standard of WHO, the blood pressure of human normal is systolic pressure 140mmHg and (or) diastolic pressure 90mmHg, and exceeding this scope can be diagnosed as hypertension.Hypertension is common cardiovascular disease, and it is defined as body and follows bad arterial pressure persistence and increase.The hypertension being secondary to kidney, endocrine and nervous system disease is called that secondary hypertension is sick, accounts for hyperpietic's 5% ~ 10%; And not yet illustrate the hypertension of its reason so far, be called essential hypertension.Essential hypertension accounts for hyperpietic's more than 90%, normal with organ functional or organic changes such as fat and sugar metabolism disorder and the heart, brain, kidney and retinas, it is the paathogenic factor of apoplexy (cerebral infarction and cerebral hemorrhage), coronary heart disease, retinopathy, kidney damage (glomerule infraction, renal failure), research shows, the M & M of cardiovascular and cerebrovascular disease and blood pressure to increase degree closely related.
The current research of doctor trained in Western medicine is thought, essential hypertension is the result of heredity, environment, anatomical structure, adaptability, nerve, endocrine, the many-sided comprehensive function of body fluid and hemodynamics, is that some congenital hereditary gene a kind of and many pathogenic supercharging factors and physiological reduce pressure factor interaction and the multi-factor disease that causes.Except foreign genetic element, high sodium low potassium meals in life, Bad Eating Habit and overweight, fat, the long-term psychentonia such as to drink, lack motion etc. and all likely bring out hypertension.So the cooperation outside Drug therapy and between non-drug therapy is focused in hypertensive treatment clinically, namely focuses on the cooperation between lifestyle modification and antihypertensive drug therapy.The antihypertensive drugs of the clinical frequent application of doctor trained in Western medicine mainly contains calcium ion antagonist (CaA), angiotensin-convertion enzyme inhibitor (ACEI), β body blocker, this four class of diuretic, secondly C receptor blocking agent, vasodilation etc. are also had, these medicines all can have larger side effect usually, also costly, toleration and the compliance of Drug safety and patient have much room for improvement price.
The most onset of hypertension is slow, progressive, as long as with arteriotony rising with lastingly for disease, also has dizziness in addition, has a headache, neck plate is tight, fatigue, cardio palmus shape.The traditional Chinese medical science belongs to the disease categories such as Chinese medicine is dizzy, headache to hypertensive elaboration, and its pathogenesis is due to negative and positive of qi and blood imbalance, makes brains hollow, and venation is lost and supported, or clear sun is not opened up, or fire is disturbed key clearly and created all diseases of hypertension.After hypertension is formed, internal injury is long-pending damages in stagnation of phlegm-damp in middle-JIAO, deficiency of qi and blood, deficiency of kidney yin, and the existence of intermediary's pathogenesis such as hyperactivity of YANG due to deficiency of YIN further develops, if qi and blood stagnation is in brain, then can become cerebral thrombosis and apoplexy, or stasis blocking in the heart be then the thoracic obstruction, angina pectoris.If QI and blood superinverse, hold expectorant under the arm and hold fire under the arm in clear key, then can occur cerebral hemorrhage apoplexy.Damage with the passing of time if internal injury is long-pending, hinder in kidney spleen, make kidney lose folding, board loses vaporization, and retention of water-damp in the body, namely the disease such as edema, renal failure occurs.
Chinese patent application 200710014082.5 discloses the hypertensive Chinese medicine composition of a kind of orally taken for curing, the crude drug of its effective ingredient mainly comprises: Ganoderma 6 ~ 9 grams, Radix Angelicae Sinensis 6 ~ 12 grams, Cordyceps 5 ~ 10 grams, Radix Gentianae 3 ~ 6 grams, Ramulus Uncariae Cum Uncis 3 ~ 12 grams, Folium Apocyni Veneti 6 ~ 12 grams, the Cortex Eucommiae 3 ~ 6 grams, Semen Cassiae 10 ~ 15 grams, Spica Prunellae 9 ~ 15 grams, Concha Margaritifera 10 ~ 20 grams, 4 ~ 8 grams, Radix Glycyrrhizae and Pheretima 5 ~ 10 grams.This traditional Chinese medicine composition for treating hypertension has determined curative effect, the advantage of non-relapse after healing, but crude drug cost is high, and drug price is expensive, is not easy to apply.
Current medical circle is thought, essential hypertension is a lifelong participation disease, and not yet report has any medicine thoroughly to cure hypertension at present, and patient needs long-term taking anti-hypertension treatment.Antihypertensive drugs needs to apply for a long time or all the life, the toleration of Drug safety and patient is very important, little and the efficacy stability of Traditional Chinese Medical on Treating Hypertension drug side effect, can long-term safety medication, has a extensive future, but it is not remarkable to there is effect in the hypertensive Chinese medicine of existing prevention and therapy, onset waits not enough slowly, seeks a kind of Be very effective, rapid-action, the pharmaceutical composition of taking convenience, has great importance to the clinical treatment of essential hypertension.

Pharmaceutical composition pharmacodynamic study of the present invention:
Test one: the experimentation of medicine composite for curing original hypertensive rat of the present invention
1, experimental animal: the Wistar rat of SPF level health 10,10 ~ 12 week age, body weight 180 ~ 220g, male, be set to Normal group.Original hypertensive rat (SHR) 50, SPF level, 10 ~ 12 week age, body weight 200 ~ 240g, male, be divided into 5 groups at random, be respectively model control group, positive controls, high dose group, middle dosage group and low dose group, often organize 10.
2, trial drug and dosage regimen:
Drug test group of the present invention: trial drug is the Chinese medicinal tablet of the present invention that the embodiment of the present invention 3 obtains, and grinds rear water into powder and is deployed into the solution that concentration is 0.6g/ml, 0.4g/ml and 0.2g/ml, for subsequent use.High dose group concentration is the drug solution of 0.6g/ml, middle dosage group concentration is the drug solution of 0.4g/ml, low dose group concentration is the drug solution of 0.2g/ml, high dose group (2.4g/kg), middle dosage group (1.6g/kg) and low dose group (0.8g/kg), according to dosage morning every day, late each gastric infusion are once, successive administration 30d.
Model control group: use isometric(al) normal saline every day early, late each gavage once, continuous gavage 30d.
Positive controls: positive control drug is kendir pressure-reducing sheet (the accurate word Z20093153 of traditional Chinese medicines, No. 2 TCM Factory), grind the solution that rear water is deployed into 0.6g/ml into powder, by dosage morning every day of 1.2g/kg, late each gastric infusion once, successive administration 30d.
Normal group: use isometric(al) normal saline every day early, late each gavage once, continuous gavage 30d.
3, the mensuration of blood pressure, heart rate: before first gastric infusion after 2h and last administration 2h, measure tail systolic arterial pressure and the heart rate of each group of rat.Before pressure measurement, rat is put into (37 ± 1) DEG C electrothermostat preheating 15min, survey 3 times continuously during pressure measurement, average as measured value.
