Despite the wide distribution of such drugs, many often have a question about what are vasodilators. These drugs are able to somehow expand the lumen of blood vessels, facilitating the work of the heart and accelerating blood flow. Today, these drugs are very popular. This is due to the fact that drugs of this type act in various ways: they reduce the tone of the smooth muscles of the vessels or eliminate their spasm.
What are vasodilators
All medicines of this group are divided into two categories: myotropic and central action. The first group includes drugs that affect smooth muscle: Papaverine, Chlorazizin, Dibazol, Diprofen, Theobromine, Eufillin. The second group of drugs mainly affects the central nervous system and venous vessels. This is the drug "Reserpine", sympatholytic, ganglioblocking and adrenolytic drugs. The use of several groups of medicines can expand the range of their application in practice.
What are vasodilators for?
The list of diseases for which these drugs are used is quite large. One of the most famous can be called angina pectoris. In this case, blood vessels are reduced in the vessels that supply the heart cells with nutrients and oxygen.
Because of this, a person experiences pressing chest pain. In such cases, the drug "Nitroglycerin" is most often used. It belongs to the group of nitrates of short duration. An expanding effect on the heart vessels is provided by such drugs as Verapamil, Amidaron, Eufillin and so on. Vasodilators such as Xanthinol Nicotinate and Pentoxifylline are used to
dilate the vessels of the peripheral circulatory system. There are also drugs to expand the vessels of the head. The most popular among them are the medicines “Isosorbide dinitrate” and “Isosorbide mononitrate”. They improve blood flow in the vessels of the brain. To achieve an early effect, vasodilator drops are used. Thanks to such medicines, many life-threatening diseases can be avoided.
Folk remedies
In some cases, vasodilator herbs can be used. They soothe and relax the smooth muscles of blood vessels, increasing their width. As a result, blood circulates faster, and the load on the heart decreases. Herbs are used for many heart diseases, especially for hypertension. The most popular and effective “green medicines” include the following: chamomile, visnaga, hawthorn, tea bush, parsnip, and bloated fruit. Use such vasodilators should be used with caution. First of all, you need to consult a doctor. Strictly follow the instructions and treatment plan. Despite the natural origin of medicinal herbs, they can easily be harmful to health. Improper use can lead to negative consequences.
