How do drugs that improve cerebral blood flow

Treatment of insufficiency of cerebral circulation involves the use of medications that dilate the blood vessels do not permit blood clots, resolve already appeared. Usually such drugs have a beneficial effect on memory and attention.

The main feature of the brain is that it is the only body that does not contain glycogen. For this reason, nerve cells are very sensitive to lack of oxygen. Five minutes after stop of blood supply begins the death of nerve cells. It is therefore very important to ensure proper blood supply to this organ. Great importance is given to the autoregulation, which is to maintain a stable blood flow independent of fluctuations in blood pressure.

Feature of drugs that improve blood flow to the brain

Prevention and treatment of insufficient blood supply involves the use of vasodilator drugs. They do not allow to stick together platelets are responsible for normal blood clotting. To improve blood circulation are also used antispasmodics, blockers of calcination vessels.

It should be noted that there is still no drugs that act topically only on the blood vessels of the brain. For this reason, when drawing up the regimens the role of anticoagulants and antihypoxants, which should restore the self-regulation of blood supply of the brain.

How they work medications

The most popular vasodilator drugs are "Cinnarizine" and "Nimodipin". They lead to relaxation of smooth muscles of blood vessels, increasing the lumen. These drugs from this is that they do not reduce the blood pressure and do not affect the General circulatory system.

Anticoagulants help to protect the brain from blood clots. They block the formation of fibrin and quickly resolve already existing clots. Such drugs include "Heparin", "Fenilin and others.

Antiplatelet agents prevent the aggregation of platelets and erythrocytes. Because of this, they do not stick to the walls of blood vessels. The most famous is "Aspirin".

Today there are many different drugs that have a beneficial effect not only on blood flow to the brain and improve memory, metabolism of brain cells. These tools include "Elfaba", "Actovegin", "Vazobral" and others. They enhance the transmission of nerve impulses, accelerate the processing of glucose by nerve cells, and remove free drugs.

Despite the fact that there are now many drugs that are beneficial acting on the brain, you should remember, is to assign them can only be a doctor. The fact that those funds that operate on the state of the General circulation can lead to the opposite effect if used incorrectly.
