The principle of high blood pressure medicine is to dilate blood vessels

Instead of dilating blood vessels, such as Rainforest Holdings' Alishu is to adjust the digestion and absorption function to strengthen the absorption rate of nutrients taken by the body, reduce the content of triglycerides in the blood, inhibit platelet coagulation, and make the oxides and lipids in the blood not easy to form thrombosis. Effective in lowering blood pressure.

Hello, usually high blood pressure is contraction, but it causes high blood pressure to have both contraction and expansion. The presence of this symptom in the blood vessels alone is not necessarily hypertension, and the common symptoms and their characteristics are as follows:

1. Dizziness: manifested as transient or persistent dizziness, often appearing when squatting or standing up;

2. Headache: the pain is located in the back of the head or temples, and most of them are persistent dull pain or throbbing pain;

3. Insomnia: mainly manifested as difficulty falling asleep, many nightmares, and easy awakening;

4. Irritability and palpitations: mostly related to autonomic nerve dysfunction;

5. Memory loss: manifested as distraction and recent memory decline;

6. Limb numbness: numbness of fingers and toes is common or there is a sense of ant walking.

Analysis:

Hello, according to what you said, the dilatation of blood vessels will lower blood pressure.

Guidance: When blood pressure is dilated, blood pressure will drop accordingly. This is also the principle of antihypertensive drugs. Blood pressure is mainly to measure the pressure of blood vessels by blood pressure, after the blood vessels dilate, the pressure of blood on the blood vessel wall decreases with the expansion of volume, so the pressure decreases.

Hello, the main reason for the bulging blood vessel is the poor blood return, blood stasis, and increased venous pressure.

If you need to stand and sit for a long time, it is best to wear a pair of elastic stockings, which can promote blood return and prevent varicose veins.

If there is anything needed.

As long as the drug is taken within the safe range of the drug, even if the antihypertensive drug is taken for a long time, it will not cause adverse factors to the blood vessels, and it will not cause the blood vessels to become brittle and cause the rupture of the blood vessel wall. In fact, as long as we take the medicine properly, then taking the blood pressure medication correctly is equivalent to taking care of our blood vessels. The main principle is to relax the blood vessels that were originally tense and congested, so that the pressure circulating in the blood vessels is reduced.

This will bring our blood pressure down to the desired level.

No. The antihypertensive drugs that dilate blood vessels are mainly calcium channel blockers, such as amlodipine and nifedipine, which relax the vascular smooth muscle and relax the vasodilation by regulating the body's antihypertensive mechanism, rather than causing antihypertensive effect by changing the structure of the blood vessels, so it will not lead to serious vasodilation, in addition, the blood vessels themselves also have a certain elasticity, so patients can follow the doctor's instructions to use them with confidence.

No, the principle of antihypertensive drugs is generally through binding to receptors, and the number of receptors is limited, so no matter how much you eat, it will not cause serious vasodilation. But there will be a certain ***.

The use of vasodilators does not affect the elasticity of the blood vessel wall, on the contrary, controlling blood pressure has a good preventive effect on the occurrence of arteriosclerosis.

This is not very clear, but the vasodilator antihypertensive drug is not to dilate the blood vessels to lower blood pressure, there may be a certain ***.

In ** angina, the use of vasodilators is a matter of course, however, the course of coronary heart disease patients is usually long, angina attacks can not disappear within a few years, how to correctly use vasodilators?

Commonly used vasodilators include nitroglycerin (trinitroglycerol), heartache (isosorbide nitrate), long-acting nitroglycerin (tetranitroquateranitol), etc. In recent years, many experts have proposed that nitrate vasodilators sometimes have the phenomenon of "rapid drug resistance", which should not be taken continuously for a long time, and in principle, intermittent application is better, which is very reasonable. In clinical work, patients have angina pectoris, most of which are occasional and last only a few minutes, and timely application of nitrate vasodilators can immediately relieve the symptoms, so there is no need for long-term use.

Patients with frequent episodes of angina pectoris can continue intravenous nitroglycerin for a short period of time, or consider alternating with other drugs, such as diltiazem (diltiazem) for those with frequent angina attacks, which is not prone to drug resistance. If the onset of angina pectoris cannot be completely controlled during the medication, the addition of nitrate vasodilators can achieve better efficacy.

At present, there are many controlled-release and sustained-release preparations of vasodilators, which have a long time of action in the body, and some patients with acute myocardial infarction can choose these long-acting preparations to reduce the pain of patients when they have frequent angina. However, it is generally not advisable to use it uninterrupted for a long time.

Telangiectasia, which can be primary, such as vascular nevus, hereditary benign telangiectasia, etc. It can also be secondary to diseases such as scleroderma and rosacea.

Telangiectasias are generally divided into two categories: primary and secondary. Originality, mostly hereditary, parents have the phenomenon of red face.

For telangiectasia, you can go to a regular hospital for treatment in time.

Any medicine will have an impact on our body during our use, but in order to prevent our body from further damage, taking medicine is also an essential step.

No. Because these drugs are produced after many clinical trials and tests by relevant departments, taking them according to the instructions will not cause the blood vessels to dilate too severely.

This antihypertensive drug it does not cause dilation too much, it is a drug that inhibits the dilation of blood vessels, and this drug is aimed at this condition, so it does not cause serious disease.

Oral vasodilators can cause vasodilators to dilate too severely. Therefore, the dosage of medicine must be well controlled, and if the blood pressure has stabilized, do not take the medicine continuously.

1. Vasodilators can dilate cardiovascular and cerebrovascular vessels and improve blood flow in coronary arteries or cerebrovascular vessels. It can also dilate the peripheral blood vessels, reduce the vascular resistance and blood viscosity, so that the blood pressure is lowered, but this antihypertensive effect is not obvious; On the other hand, due to the dilation of peripheral blood vessels, blood volume can be increased, which can also increase blood pressure. Just as some vasodilators can be used for shock, it is the expansion effect of vasodilators that is used to increase blood pressure.

2. During the infusion, if saline is used to dissolve the drug, it will also directly increase the blood volume and increase blood pressure.

Therefore, if the blood pressure of hypertensive patients is high, they should control the blood pressure at a safe level on the basis of lowering blood pressure**, and then take infusion**. In addition, when applying vasodilators, do not use saline; Nor can it rely solely on infusion** high blood pressure.

Vasodilator drugs are mainly to dilate vascular smooth muscle and dilate peripheral blood vessels, taking vasodilator drugs is easy to cause dizziness, palpitations, hypotension, etc., taking vasodilator drugs to consider age, gender, general condition, blood pressure, liver and kidney conditions, whether there is bleeding, prothrombin time, coagulation time, platelet count is normal, need to comprehensively consider whether vasodilators can be used, whether there are contraindications. Any drug has a certain amount of medicine, which will cause some harm to liver and kidney function, so the medication needs to be appropriate, especially within the accurate dosage range, and the drug that can not dilate the blood vessels excessively is easy to cause the patient to have symptoms of prostration, palpitation and dizziness in the early stage, so it is necessary to closely observe the patient's symptoms before using the drug, because some people are relatively large and the symptoms are more obvious.

Any medication is ***, and prolonged use of vasodilator drugs may cause bleeding and may cause adverse consequences such as allergies. For the situation you mentioned, if you have a disease, you should go to a regular hospital for examination in time, find out**, and use drugs under the guidance of a doctor**. You should have a regular lifestyle, avoid strenuous exercise, eat lightly, and drink plenty of water.

Drugs that dilate blood vessels are generally **, and those who have vascular diseases are harmful to the heart and kidneys.

The more commonly used vasodilator drug niacin, which has the effect of dilating cerebral blood vessels, increasing blood flow, promoting nerve cell metabolism and lowering cholesterol. The usual dosage is 50 100 mg, 3 times a day orally, or 200 300 mg added to 5% glucose 500 ml intravenous infusion, once a day, 7 to 10 days for a course of treatment.

4) Calcium channel blockers, such as cerebral prozine, flucinazine, and nimodipine, can act on the calcium channels on the cell membrane, prevent calcium ions from entering the cell, relieve vascular smooth muscle spasm and play a role in dilating blood vessels. It can selectively act on cerebral blood vessels, increase cerebral blood flow, and improve brain microcirculation. Usual amounts:

Brain prozine 25 50 mg, orally 3 times a day; Flucinazine 8 12 mg once nightly; Nimodipine 20 40 mg orally 3 times a day.

5) Petadine has a strong effect of dilating cerebral blood vessels, improving cerebral blood circulation and increasing cerebral blood flow. In particular, it has a stronger effect on vertebrobasilar artery system dilation. The usual dosage is 4 8 mg, 3 times a day, orally.

6) Sodium bicarbonate can increase the concentration of carbon dioxide in the blood, cause metabolic alkalemia and dilate blood vessels, increase cerebral blood flow, and improve cerebral ischemia. The usual amount of 5% sodium bicarbonate 250 ml intravenous infusion, once a day, 7 to 10 days for 1 course of treatment.

7) Karan tablets can relax vascular smooth muscle, increase cerebral blood flow, reduce blood viscosity and inhibit platelet aggregation. The usual dosage is 5 mg, 3 times a day, orally.

8) Brain pathway has the functions of inhibiting platelet and red blood cell aggregation, reducing capillary permeability and fragility, and improving cerebral circulation. The usual amount is 200 300 mg, 3 times a day, orally, or 400 600 mg added to 5 10% glucose 500 ml intravenous infusion, 1 time a day, 10 15 days for 1 course of treatment.

The specific use of it is still based on the doctor's prescription.
