What are the oral medications used to dilate blood vessels?

1) Papaverine hydrochloride has a relaxing effect on smooth muscle, especially a direct dilation effect on cerebral blood vessels. It can also reduce peripheral vascular resistance and cerebrovascular resistance, increase cerebral blood flow, and improve cerebral blood oxygen**. The usual dosage is 30 60 mg, 3 times a day orally, or 60 90 mg added to 5% glucose 500 ml intravenous infusion, once a day, 7 to 10 days for a course of treatment.

2) Cyclic mandelin (antithrombotic pill) The effect is similar to papaverine, which can relax vascular smooth muscle, dilate the blood vessels of the brain, kidneys, coronary arteries and limbs, increase blood flow, and improve microcirculation. Its effect is mild and long-lasting. The usual dosage is 100 200 mg, 3 times a day, orally.

3) Niacin 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.

Lunan Xinkang has a good effect, as well as petadine, nimodipine, and sibiline.

The main cause of vasodilator drugs is hypotension caused by vasodilation, which in turn causes a series of symptoms. Patients with mild symptoms may have symptoms such as dizziness, dark eyes, limb weakness, cold sweats, palpitations, and oliguria, and severe patients may present with syncope or shock. Exercise properly, have a regular life, and prevent excessive fatigue, because extreme fatigue will lower blood pressure.

It is necessary to maintain a good mental state, appropriately strengthen exercise, improve physical fitness, and improve the regulatory function of nerves and blood vessels. Caution must be exercised when using these drugs. The patient's age, gender, general condition, presence of hypertension, bleeding tendency, liver function, prothrombin time, coagulation time, and platelet count should be considered.

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.

It is a medicine with three points of poison, and any medicine has ***.

1. Low blood pressure, because vasodilators can dilate peripheral blood vessels, they can lower blood pressure, and when the drug is used excessively, it can cause blood pressure to drop too low.

2. Rapid heart rate, due to the decrease in blood pressure due to vasodilators, the heart rate can be reflexively increased, and when the heart rate increases significantly, it can also lead to the symptoms of palpitation.

The "antihypertensive drugs" around you, which you insist on taking every day, can dilate blood vessels or help you stabilize blood pressure.

Commonly used drugs for blood vessel dilation in clinical practice are, compound Danshen tablets, thrombosis, Xuesaitong, etc., it is recommended to go to a regular hospital for symptomatic treatment**, usually exercise more, pay attention to keeping warm every day, and drink more water. If the blood vessels are softened and the garbage in the blood vessels is removed, then the diameter of the blood vessels will be correspondingly larger, and the blood will be more smooth, generally these foods can soften the blood vessels, such as black fungus, vinegar, grape seeds, corn, soybeans, and black sesame seeds can play a role in softening blood vessels and dilating blood vessels.

The most commonly used vasodilators.

Niacin has the effect of dilating cerebral blood vessels, increasing blood flow, promoting nerve cell metabolism and lowering cholesterol, and has the effect of strengthening cerebral blood vessels, improving cerebral blood circulation, and improving cerebral blood flow.

Stick to walking for a certain amount of time every day, and several studies have proven that walking is the best exercise to prevent varicose veins. With each walk, the soles of the feet act like a pump to pump the blood back, preventing the pressure of blood backflow.
