To give a man an erection, there must be a pill with a drug that relaxes the smooth muscle of the walls of the arteries in the penis, provocative, that they are opened. The blood flows into the cavernous bodies, and blood pressure stretches the penis, giving him an erection.
However, the pill can`t end to be worn a General relaxing the smooth muscle (as fentolamina). Just as she relaxes in this case entirely from the smooth muscle of the whole body of man, and could cause many problems. So, it turns out that what we need to create an erection is a drug that acts only on the smooth muscle in the arteries of the penis.
But it is possible to do it? For the best understanding of how this drug, and many who have made AM look at this very important pump that our body has the heart. Different quantity of blood that is needed at different moments in different reports of the body. To better understand this statement, that`s look at this example:
For all the food they have eaten after a meal is digested, the body sends more blood to the stomach. But he will cut the majority of the blood that flows to the stomach when it is needed for other parts of his body, for example, for the arms and legs when he is running in a marathon.
In other words, the brain controls all of these processes. And the borders or on the contrary, to increase blood flow to various reports of his body, there is a set of keys, which are under the control of his brain.
The penis is an exception in this case, since light the necessary blood flow and clear, and under the control of the brain to be. To understand how this valve is controlled very closely, we will answer the question: What is the arterial flow controlled by the brain?
What is the opening mechanism of the flaps?
In any human body, the flaps open and close, with the help of the muscle, which are located in the walls of arteries. Once they loosen muscles, the arteries are opened, which is translated into an increase of the blood-colored river. The brain controls this process by means of the special mission of the chemical message in the reply of the flap immediately.
But as a chemical message sounds too general, that `s see that the measures would include, exactly. Then, as the body opens the door in any part of the body? This process consists of four steps:
1 A sign is from the brain through a nervous fiber especially sent, which ends in a nervous cell NANC in an artery. NANC nerve cells it is able to create the nitric oxide.
2
The NANC nervous cell injected nitrate oxide in the blood and the nearby cells.
3 Then, stimulates nitric oxide a called ferment of Guanilato ciclasa in the surrounding cells, and begins this ferment of guano Sina monophosphate (cGMP) to produce.
4 GMP can relax the smooth muscle, which can increase the blood-colored river.
This chemical machine is something the brain used to increase blood flow to various reports of the body. But there is one part: the other ferment reputation defused (PDE) the GMPc fosfodiesterasa. When the brain stops sending the signal, it disappears all CGMP is because the PDE is to defuse. In this way, can activate the brain, and defuse the flap every time he wants.
As a chemist, this mechanism are connected with an erection?
When the brain is sexually excited, it sends a signal to the penis. The nerve cells of the cavernous body of penis’ to begin to produce nitrate oxide, what it leads to the creation of CGMP. The GMPc provoked, that he the arteries in the cavernous bodies to expand, causing a large quantity of blood flows to the penis. The germ of blood is so built that the penis expands as a sphere and replaced.
Many reasons can be causes of the problem of erectile dysfunction in his people. But one of the most common reasons is that the arteries in the penis to expand the not enough when the brain sends the signal. The man moves on sexually, and the nerves of the penis NOT produce. Then, why doesn, AOT produce an erection? This is because the quantity of generated CGMP is not enough to maintain an erection.
The form in which one tries to Revatio sildenafil, to decide this issue is quite ingenious, and consists in the following question: How can you create a drug that only devoted the cover of the penis?
How to treat erectile dysfunction with revatio sildenafil citrate?
There are three types of blood flow to the penis at least he is increasing:
The first form is to increase the quantity of nitric oxide produced in the penis.
The second includes the increase in the quantity of cGMP in the penis the nitric oxide produced in response.
The third eliminates the PDE in the penis, so that the quantity of cGMP increases, instead of cut to obtain the PDE. This is the method used and buy Revatio.
All that is larger the quantity of CGMP, everything is larger, the flow of blood, and the flow of blood is greater the larger is the degree of erection.
Viagra uses the third technique, because of an interesting peculiarity of the PDE. The human body produces over 11 different types of PDE. The penis is only one way, however, has found: the PDE5. When once this fact was revealed, the problem seemed much easier. Now: What could he do Pfizer, is he to make a chemical product that could block the PDE5 and it will affect anything. The problem of erectile dysfunction can be sold by the blockade of PDE5 easy GMPc which could be stored in the penis and increase blood flow there. And what is no less important, intended to go to all without affecting other parts of the body. That would be the treatment of impotence with revatio sildenafil not now, when there was no single type of PDE, they are in the penis.
As the PDE5 Revatio works just block?
The PDE5 is an enzyme that accepts GMP and breaks it to the top. Pfizer needed to do to make a chemical product that PDE5 thinks of his work. Soon they have they provided to be familiar with a chemical product that they will fit perfectly in the enzyme PDE5 and he has taken it out of combat. The chemical product that was discovered by Pfizer, sildenafil citrate has been called.
One tablet of revatio sildenafil citrate is a packing. If a man takes a pill of Viagra, sildenafil citrate, which remains in the blood-colored mountain torrent for about four hours. The drug is flowing throughout the body, but is concerned only the PDE5 enzyme in the penis.
Good, let’s go in `s summary of our history more interesting and adventurous Viagra:
After a man he takes a pill of Viagra, sildenafil citrate, which enters its blood-colored mountain torrent, and joins in the PDE5 enzyme in his genital organ together and defused the bulk of them.
If a man is sexually stimulated, the brain sends the message to the NANC cells in his penis that produces nitrate oxide.
Do you believe that nitric oxide of the CGMP, which relaxes the arteries in the penis without any type of barriers, such as PDE5 was defused.
As result, extend all the arteries in the genital organ entirely of penis and it is stored and a man has an erection.
This is the perfect solution to a problem of impotence, some minor problems.
What should I know before I buy revatio sildenafil?
The possible side effects of revatio:
Almost the entire drug that has some side effects like any drug flows through the body and the parts of the body may include, without intention, and then the Revatio does it.
The first side – effect is due to an indirect effect, that there is a Revatio. Because we know that an effect of the blocks PDE5, but also on the has PDE6, which used in the cone cells in the retina, making it the Revatio sometimes seeing the color can influence. Some people who take Revatio will he begin to see everything with a bluish coloring and the colors of the different ways to notice (generally the green and blue colors). Therefore, they are banned, some men taking revatio sildenafil (for example, the pilots within 12 hours of a flight).
The second side – effect seems if revatio sildenafil is held pectoris with medications for nitroglycerin for angina. If nitroglycerin is taken together with sildenafil citrate, the nitric oxide has more the blocking of PDE5 can cause them some more serious health problems.
There are also some minor, if we can put it that way, the side effects as headache (as a result of excess pressure in the lining of the brain). And there are more serious side effects as heart attacks. The ability to reach a heart attack, is the main reason by revatio sildenafil citrate is a prescription drug and a drug-free sale as of the aspirin. There should be a permit his doctor to drink, after he assured himself of the causes of a heart attack.
It may also some men who buy revatio sildenafil, painful erections, of long duration have (the erection that lasts 4 hours or more).
One side effect is more dependence. Some men (the majority of young men who really needs not because they do not have erectile dysfunction, but for a Neuschöpfungsart hold) it can end with the inability to have an erection without taking revatio.
Also there can be side effects such as:
– Pain in my heart, numbness of any report of the body
– Loss of memory
– More difficult to, swelling of the mouth, nose, face down, to breathe the lips
– Weakness
The diarrhea
Other side effects of Viagra can be observed.
Does not have Revatio Sildenafil, Viagra Cialis and Levitra with nothing to do?
Viagra is a success all over the world they wanted to develop with other pharmaceutical companies, a similar drug. They end with the development of new chemical products to the enzyme PDE5 and the creation of some new drugs to block as (tadalafil) Cialis, and Levitra (vardenafilo).
These drugs work just as well as sildenafil citrate, blocking the enzyme PDE5. (Tadalafil) Cialis, and Levitra (Vardenafil) to help in patience with the failure that causes problems is the river of blood, and they only work when a man sexually excited. But depending on the chemical products used are different, there are some important differences between these drugs:
Revatio sildenafil vision problems caused in color.
Cialis causes muscle pain (similar between when the flu) are in 5 percent of men.
Viagra and Levitra are effective for about 4 hours after they take a pill, Cialis during the so-much for a day can be effective.
How can I buy Revatio sildenafil citrate?
If you want to buy tablets of revatio, which is adapted to the moment to do it. Do not waste time and energy thinking about where to buy tablets of revatio. The best way to buy tablets of revatio, is to make it in line at the pharmacy that supplies the men with revatio the best quality.
