What methods or medications are available to dilate veins?

No one told you, so I'll tell you:

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.

I believe that the questioner is a medical professional, and if you don't even know this question, and there is such a way to get the answer, then how can your patient be protected? Study hard! Practicing medicine is not an ordinary profession, because it is facing life!

Remember: practicing medicine is like walking on thin ice, like facing the abyss!

Answer]: This product is a powerful vasodilator, which can directly relax the smooth muscle of arterioles and venous vessels, and is a nitrodilator drug, which is metabolized to produce nitric oxide (NO) in the smooth muscle of Huaipei blood vessels, and NO has a strong effect of relaxing vascular smooth muscle.

This lead crack VIP-lowers blood pressure, reduces the pre- and afterload of the heart, thereby reducing the myocardial load, reducing myocardial oxygen consumption, and increasing the output of the left ventricle in failure. This product is a non-selective vasodilator drug, which has a rapid effect, short maintenance time, and does not reduce coronary blood flow, renal blood flow and glomerular filtration rate. Generally, intravenous infusion, adjust the drip rate and dose to control blood pressure at a certain level.

Correct Answer: a

Analysis: Sodium nitroprusside can dilate arterioles and veins at the same time, and reduce cardiac pre- and post-load at the same time.

Vasodilators.

1) Niacin is taken orally half an hour before meals, and can be taken for a long time, and the dose is controlled to be red on the face and fever after taking the drug.

2) Scycyamine (654-2) can relax smooth muscles and relieve spasm of small blood vessels. The oral effect is poor, and intramuscular injection or intravenous infusion is often used.

3) Tolazoline is a blocker, which has the effect of dilating blood vessels and relieving spasm, and can also be injected intramuscularly. Patients with gastric ulcers and heart disease should not use it.

4) Vasostatin (padutin) is a hormone that dilates blood vessels, and is contraindicated by people with high blood pressure and heart disease.

5) 5% sodium bicarbonate can neutralize acidic metabolites in tissues, release CO2, dilate inner ear microvessels, and improve microcirculation.

6) Papaverine has obvious effect on relaxing smooth muscle, and also has a good effect on cerebral blood vessels and coronary arteries.

7) Cerebral prozine can dilate capillaries and reduce vascular fragility.

8) Inhalation of 7% CO2 and 95% O2 mixed gas can dilate microvessels, increase the partial pressure of oxygen in endolymphtic fluid, reduce pH value, and can also be inhaled with 7% CO2 alone.

3.Dilate microvasculature and reduce blood viscosity.

1) Salvia miltiorrhiza can dilate blood vessels, reduce plasma viscosity, reduce fibrinogen content, oral or intravenous infusion.

2) Ligustrazine can dilate small blood vessels and reduce platelet aggregation.

3) Trichophyllin can reduce the aggregation of platelets and fight thrombosis.

4.Calcium channel blockers Intracellular calcium overload can cause vasoconstriction, decreased red blood cell deformability, and impaired peripheral circulation, which is the cause of vertigo. Sibelium is a selective calcium blocker that prevents intracellular calcium overload, improves cochlear microcirculation, reduces vestibular excitability, enhances neuronal hypoxia tolerance, and inhibits myocardium and lowers blood pressure without general blockers***.
