Description

Technical Field

[0001] The present invention relates to the technical field of traditional Chinese medicine. More specifically, it relates to a traditional Chinese medicine composition for treating essential hypertension, its preparation method and application. Background Art

[0002] Essential hypertension refers to the situation where, without taking medications, the clinic blood pressure measured 3 times on different days reaches 160 / 90 mmHg or higher. The average value of home blood pressure measurement or the average daytime value of ambulatory blood pressure monitoring ≥ 135 / 85 mmHg can also be diagnosed as hypertension. Referring to the hypertension diagnosis criteria formulated in the "Chinese Guidelines for the Prevention and Treatment of Hypertension" (2024): A blood pressure level of 120 - 139 / 80 - 89 mmHg is defined as normal high - value blood pressure, and a blood pressure level of 160 - 159 / 90 - 99 mmHg is defined as grade 1 hypertension. Essential hypertension is a common and frequently - occurring disease that can damage the arterial blood vessels of target organs such as the heart, brain, and kidneys, increasing the risk of cardiovascular and cerebrovascular diseases. It is a major risk factor for diseases such as stroke, heart failure, myocardial infarction, and chronic renal failure. Currently, there is a controversy both at home and abroad regarding whether to immediately initiate antihypertensive drug treatment for patients with normal high - value blood pressure and low - risk patients with grade 1 hypertension. The mainstream view is that there is currently no western medicine that can clearly benefit patients with normal high - value blood pressure. The "Chinese Guidelines for the Prevention and Treatment of Hypertension" (2024 revised edition) recommends that low - risk patients with grade 1 hypertension and low - to - medium - risk patients with normal high - value blood pressure do not necessarily need to immediately initiate antihypertensive drug treatment. The results of the national hypertension sampling survey conducted from 2012 to 2015 showed that the crude detection rate of normal high - value blood pressure in the population aged 18 and above was 39.1%, and the weighted rate was 41.3%. Based on this, it is estimated that 440 million people in China have blood pressure in the normal high - value range. A survey showed that among people over 60 years old with baseline blood pressure of <120 / 80 mmHg, 120 - 129 / 80 - 84 mmHg, and 130 - 139 / 85 - 89 mmHg, the incidence of hypertension after 10 years was 12%, 45%, and 64% respectively.

[0003] Hypertension lifestyle intervention includes maintaining a healthy diet, regular exercise, smoking cessation, alcohol restriction, less salt intake, etc. Antihypertensive drugs are divided into six categories, including diuretics, β - receptor blockers, calcium channel antagonists (CCB), angiotensin - converting enzyme inhibitors (ACEI), angiotensin II receptor blockers (ARB), and sacubitril / valsartan (ARNI). Oral antihypertensive drugs can better control blood pressure, but there are many adverse reactions. For example, diuretics can cause hypokalemia, hyperglycemia, etc., β - receptor blockers can lead to dyspnea, arrhythmia, CCBs can cause tachycardia, dizziness and headache, and ACEIs can cause irritating dry cough. For patients with essential hypertension, especially those with normal high - value blood pressure and grade 1 hypertension, who are not suitable for direct treatment with western medicine for the time being, traditional Chinese medicine can be selected to treat this type of hypertension.

[0004] Therefore, it is very necessary to develop a traditional Chinese medicine with no adverse reactions that can effectively and steadily lower blood pressure, gently lower blood pressure, and lastingly lower blood pressure. Summary of the Invention

[0005] In view of the above technical problems, the first object of the present invention is to provide a new traditional Chinese medicine composition for treating primary hypertension. This traditional Chinese medicine composition has very good effects in treating primary hypertension, can improve clinical symptoms such as headache and dizziness related to primary hypertension, improve multiple cardiovascular metabolic factors such as blood lipids, blood sugar, and uric acid, reduce damage to target organs such as the heart, brain, and kidneys, and improve the quality of life.

[0006] The second object of the present invention is to provide a preparation method of the above traditional Chinese medicine composition.

[0007] The third object of the present invention is to provide a traditional Chinese medicine preparation using the above traditional Chinese medicine composition as an effective active ingredient.

[0008] The fourth object of the present invention is to provide the application of the above traditional Chinese medicine composition and traditional Chinese medicine preparation in the preparation of drugs for treating primary hypertension.

[0009] To achieve the above objects, the present invention adopts the following technical solutions:

[0010] In the first aspect, the present invention provides a traditional Chinese medicine composition for treating primary hypertension. The traditional Chinese medicine composition is mainly made from the following raw materials in parts by weight: 20 - 60 parts of raw Astragalus membranaceus, 10 - 20 parts of Morinda officinalis, 10 - 20 parts of stir-fried Bombyx batryticatus, 10 - 20 parts of Plantago asiatica, 10 - 30 parts of Gastrodia elata, 10 - 20 parts of Alisma orientale, 10 - 20 parts of Pheretima aspergillum.

Pharmacological studies have shown that Plantago has rich pharmacological activities such as anti-inflammatory, antioxidant, anti-platelet aggregation, anti-aging, anti-anxiety, fatigue relief, sedation and hypnosis, immunomodulation, and neuroprotection.

[0015] Alisma: sweet, light, cold. Enters the kidney and bladder meridians. Has the effects of promoting diuresis and removing dampness, removing turbidity and reducing lipids, and relieving heat. Indications: edema, dysuria, stranguria, leucorrhea, and hyperlipidemia. Pharmacological studies have shown that Alisma has the effects of diuresis, anti-inflammatory, liver protection, blood pressure reduction, lipid reduction, anti-oxidation, regulating sugar and lipid metabolism, and inhibiting kidney stones.

[0016] Gastrodia elata: sweet, neutral, enters the liver meridian. It has the effects of calming wind and stopping spasms, calming liver yang, and dispelling wind and unblocking collaterals. It is used to treat epilepsy, convulsions, dizziness, headaches, limb numbness, rheumatic pain and other diseases caused by internal liver wind. Pharmacological studies have shown that Gastrodia elata has antihypertensive, antilipidemic, anti-oxidative stress, anti-inflammatory, brain protection, anti-epileptic, anti-dizziness, analgesic and other effects.

[0017] Bombyx batryticatus: salty, pungent, neutral in nature, enters the liver, lung, and stomach meridians, can dispel wind and enter the heart, lung, liver, and spleen meridians, and has the effects of dispelling wind and stopping spasms, resolving phlegm and dispersing knots, clearing away heat and detoxifying. It is used to treat diseases such as liver wind with phlegm, epilepsy and convulsions, acute convulsions in children, and wind-heat headaches.

Pharmacological studies have shown that earthworms have thrombolytic, anticoagulant, antihypertensive, anti-inflammatory, antipyretic, sedative, and blood pressure-lowering effects.

[0019] Hypertension belongs to the disease categories of "dizziness" and "headache" in traditional Chinese medicine according to its clinical symptoms. Clinically, symptoms such as dizziness, headache, irritable mood, and numbness of limbs can be seen. The location of the disease of hypertension is in the brain orifices, and it is closely related to the heart, liver, spleen, and kidney. The pathological changes are mainly the imbalance of qi, blood, yin, and yang in the heart, liver, spleen, and kidney. The pathological factors are nothing but wind, fire, phlegm, stasis, and deficiency, belonging to the syndrome of deficiency in origin and excess in superficiality. For patients with unclear hypertension symptoms and those in the early stage of essential hypertension, from the perspective of "preventive treatment of disease", timely syndrome differentiation and intervention are the keys to preventing disease before its occurrence, preventing the progression of the disease once it occurs, and preventing recurrence after recovery. Spleen-kidney yang deficiency is the root of the disease, and phlegm-dampness is the pathological product as the superficiality. "Dizziness is not caused without phlegm", the spleen is the source of phlegm production, and the spleen is in charge of transportation and transformation. Bad habits such as mental factors, addiction to tobacco and alcohol, air conditioning and cold baths, lack of exercise, preference for fatty, sweet, thick, and greasy foods, preference for cold drinks and raw and cold foods, overwork, and staying up late consume the yang qi of the spleen and kidney. When the spleen fails to transport and transform, the distribution and metabolism of water and beverages are obstructed, and then dizziness occurs. Kidney deficiency leads to heavy head and high shaking, and insufficient marrow in the brain leads to dizziness and tinnitus. If the congenital primordial yang is insufficient and the fire of the gate of vitality fails to warm and nourish, yang deficiency generates cold, phlegm-dampness is internally generated, blood vessels are stagnated, the blood vessels are not warm, yin pathogens accumulate, collaterals lose nourishment, and internal stirring of virtual wind occurs, then the collaterals contract spasmodically, resulting in dizziness and headache. Hypertension is based on spleen-kidney yang deficiency, with phlegm-dampness mutual binding and liver wind internal stirring as the superficiality. The treatment should be based on the methods of tonifying the spleen and kidney yang, resolving phlegm and removing dampness, and calming the liver wind.

[0020] The compatibility significance of the traditional Chinese medicine composition of the present invention lies in: essential hypertension mostly belongs to the syndrome of deficiency in origin and excess in superficiality, and both the origin and superficiality should be treated, with consolidating the origin as the main. Morinda officinalis is sweet, pungent, and slightly warm, tonifying the kidney yang, expelling wind and removing dampness. Astragalus membranaceus is warm in nature, good at tonifying the qi of the lung and spleen, and helping the growth of spleen yang. The two together are the monarch drugs, tonifying the yang of the spleen and kidney. When spleen-kidney yang deficiency occurs, the transportation and metabolism of water and fluids are abnormal, water and dampness accumulate and coagulate, forming phlegm-dampness. Plantago asiatica is sweet and cold, entering the kidney, lung, and small intestine meridians, having the effects of eliminating phlegm, clearing heat, and promoting diuresis. Alisma orientale is sweet, light, and cold, belonging to the kidney and bladder meridians, and can promote diuresis and percolate dampness, transform turbidity and reduce lipid. The two together are the minister drugs to promote diuresis and percolate dampness. Due to insufficient spleen and kidney, the brain marrow loses nourishment, and internal stirring of virtual wind occurs. Therefore, Gastrodia elata, Bombyx batryticatus, and Pheretima aspergillum are used as adjuvant drugs. Gastrodia elata is sweet and flat, entering the liver meridian, having the effects of calming endogenous wind and stopping convulsions, suppressing liver yang. Bombyx batryticatus and Pheretima aspergillum can also calm endogenous wind and stop convulsions. The combination of the three has the effect of calming endogenous wind. The compatibility of all the drugs plays the role of tonifying the spleen and kidney, resolving dampness and calming the liver, and treating essential hypertension with insufficient spleen and kidney, phlegm-dampness mutual binding, and liver wind internal stirring.

[0119] Evaluation criteria for the curative effect of traditional Chinese medicine syndromes

[0120] According to the "Guiding Principles for Clinical Research of New Chinese Medicines" in 2002. Specifically as follows:

[0121] Marked effect: The main symptoms and secondary symptoms were significantly relieved, and at the same time, the degree of reduction in the syndrome score was 70% and above;

[0122] Effective: The main symptoms and secondary symptoms were relieved, and at the same time, the degree of reduction in the syndrome score was 30% and above, but below 70%;

[0123] Ineffective: The main symptoms and secondary symptoms were not relieved or were aggravated, and at the same time, the degree of reduction in the syndrome score was below 30%.

[0124] Note: Calculation formula: therapeutic index = [(score before treatment - score after treatment) / score before treatment] × 100%.

[0125] 1.3.4 Scoring criteria for the Duchenne Hypertension Quality of Life Scale

[0126] Patients fill in the scale truthfully according to the presence and severity of symptoms. The sum of the scores of each item is the total score of the scale. The higher the score, the better the patient's quality of life.

[0127] 1.3.5 Safety evaluation criteria

[0128] Level 1: During the test, there were no abnormalities in the routine blood and urine tests, liver and kidney function tests, and no adverse reactions;

[0129] Level 2: During the test, there were no abnormalities in the two blood and urine routine tests and liver and kidney function tests. There were mild adverse reactions, but no special treatment was required.

[0130] Level 3: Mild abnormalities in blood and urine routine tests and liver and kidney function tests twice during the trial, moderate adverse reactions, requiring timely treatment;

[0131] Level 4: During the trial, severe abnormalities were found in routine blood and urine tests twice, liver and kidney function tests, and severe adverse reactions occurred, requiring termination of the trial.
