However, still not all representatives of the stronger sex know how Viagra works. Before we look at this issue, a few words about what this unique drug is.

What do we know about Viagra?

If only a few have an idea of ​​how Viagra works, then almost everyone knows what it is intended for.

Today, any young man will tell you that the above drug helps get rid of erectile dysfunction. Indeed, it is so. However physiological treatment male impotence the drug does not provide. Then how does Viagra work? Everything is very simple. This remedy is aimed at increasing blood flow in the male genital area, as a result of which the quality of erection improves, and sex life comes back to normal. Simply put, after using the above drug, a man begins to experience a burning sexual desire. This is how Viagra works. Now let's move on to the question of how this was created unique remedy from male sexual impotence.

History of creation

Back in the 90s of the last century, employees of the Pfizer company (USA) puzzled over how to create effective medicine, which would save a person from pain in the chest with angina.

During the period of clinical testing, it was found that the active component of the drug - sildenafil - does not fundamentally affect the functioning of the heart, while the representatives of the stronger sex who participated in the studies said that this medicine significantly increased their male libido. When the participants in the experiment declared that they would not give up pills that were useless for the heart, the scientists realized that they had truly created innovative development, which was called "Viagra", which translated as "the power of Niagara Falls." This know-how caused such vivid associations.

In 1993, detailed analyzes were carried out to determine how Viagra works in men. As a result, it was found that the drug is not only effective in the fight against sexual impotence, but also safe. After this, the US authorities gave the go-ahead for the production of Viagra and the supply of the drug to the world market.

Panacea or not?

One way or another, the question of how Viagra works on men needs to be supplemented.

This restorative drug works somewhat differently than other potency enhancing drugs. The thing is that Viagra is aimed at eradicating the primary problem and most representatives of the stronger sex position the drug as a panacea. But to save own health, it is very important to know what the mechanism of operation of the above tool is. Here we should return to the question of how Viagra works for men. First of all, the drug restores function blood vessels involved in the erection mechanism. In other words, this medicine is specifically designed to get rid of erectile dysfunction. It allows you to achieve high-quality potency for a long period of time for sexual intercourse. However, when considering the question of how Viagra acts on a person, it is necessary to make a reservation: in the absence of sexual arousal, a normal erection cannot be guaranteed by the above drug! This is what men should remember.

Only taking into account this factor can we talk about the effectiveness of Viagra in terms of increasing blood flow in the male genital organ. Naturally, after intimacy and the process of ejaculation, the phallus will return to its original state.

It is important to establish the cause

At the same time, it should be remembered that the problem of erectile dysfunction varies for every person. individual character, and the speed of its solution depends on how accurately the causes of the disease can be established. And there are a huge number of them. Even minor damage caused muscle tissue, capillaries, vessels and nerve endings, may lead to sexual dysfunction, not to mention such serious illnesses like pyelonephritis, diabetes or hepatitis. According to statistics, in most cases (75%) male impotence due to physiological factors and only in some (25%) - psychological.

Of course, the question is: “How does the Viagra tablet work?” today is more relevant than ever, but regardless of whether the patient knows the answer to it or not, the first thing he should do is go to see a doctor.

Do not use Viagra without consulting a specialist

Self-medication with this drug is excluded. Why? The whole point is that active ingredient Viagra - sildanefil - immediately interacts with a huge list of medications. First on this list are nitrates, used to treat heart disease. When the latter are combined with Viagra, serious consequences may occur. Negative consequences for good health. That is why it is important to know not only how Viagra acts on the body, but also what medications it should not be taken with this drug. At the same time, it should be recognized that in 99% of cases the method in question turns out to be effective. Now you know how Viagra works. Reviews from patients indicate that the drug effectively copes with erectile dysfunction. This is stated by about 80% of men who have been diagnosed with this problem. About 15% of patients note that Viagra did not help them very much. Approximately 5% of the stronger sex were dissatisfied with the effect of this drug.

Application specifics

Many men are interested in the question of how quickly Viagra works. If you take the tablet on an empty stomach, then after half an hour you can feel a rush of blood groin area. When the drug is taken after a meal, a similar effect is achieved in about an hour. How long does Viagra last?

There is no clear answer to this question. Some patients claim that the drug works within 4 hours. Others claim that the effect of Viagra does not disappear the next morning. The remedy works differently for each man.

Side effect

In trying to solve the problem of sexual impotence, we must not forget that medications, while relieving this disease, carry the risk of side effects. Viagra is no exception in this sense. However, if you follow all the doctor's recommendations, then there is nothing to worry about. If you ignore them and overdo the dosage, the consequences can be unfavorable. For example, it is possible that your health will worsen, swelling of the face will appear, malaise, headache, abdominal pain will occur, allergic reactions. Diseases may also manifest themselves of cardio-vascular system: arrhythmia, tachycardia, ischemia, heart attack, stroke. May also be harmed digestive system, which manifests itself in the form of ailments such as colitis, gastritis, gastroenteritis.

If the patient is suffering chronic diseases heart, kidneys, adrenal glands or liver, blood cancer or anemia, then he should never take Viagra without first consulting a doctor.

When Viagra is powerless

It is necessary to take into account the fact that Viagra can not help all men. In particular, we are talking about those who have recorded low level testosterone. It is this male sex hormone that is responsible for sexual arousal. If a person has defects inner shell vessels (endothelium), then the effectiveness of Viagra will also be reduced to zero.

Such dangerous illness, such as atherosclerosis, can significantly reduce the effect of the drug.

There is Viagra for men and women

It is generally accepted that Viagra is a medicine exclusively for men. However, there is a drug for the fairer sex. Female Viagra is recommended for use by those who have low libido and lack of desire for intimacy.

Doctors are often asked what is the likelihood that the effect of taking Viagra will not suddenly disappear at the most necessary moment. This question is quite relevant for many men, because confidence in the possibility of having full sexual intercourse is the key to good relations between lovers. Doctors do not give a definite answer, since the duration of the effect of the main component of the drug on the body depends on many factors. Therefore, in order not to get into awkward situation, experts advise you to familiarize yourself with the features of Viagra and recommendations for its use.

The drug contains sildenafil citrate, which enhances the body's response to sexual stimulation. This happens due to the fact that active substance blocks enzymes that reduce the biosynthesis of nitric oxide, and this in turn promotes the expansion of cavernous tissue and increased blood flow to the penis at the time of arousal.

Unfortunately, Viagra is not a drug that quickly increases sexual desire, therefore, it will be absolutely useless for those who are not able to independently awaken their desire for sex. In view of this, it must be remembered that when complete absence libido there is no point in taking this medicine.

Instructions for use
