History of creating Viagra and how it acts

buy generic viagra online

In the 90-ies of the last century, scientists working in the American company Pfizer, were engaged in the invention of a new drug that was supposed to relieve chest pain in angina pectoris. But during the clinical trials it was found that the active substance sildenafil does not have a proper effect on the heart. At the same time, all the men who took part in the trials spoke enthusiastically about the strong side effect associated with improving potency. When most of the participants in the experiment flatly refused to return tablets that were useless to the heart, and one even tried to infiltrate the laboratory to replenish its reserves, the company managers realized that they had discovered a “gold mine”.
A new miracle cure was given the name, consisting of a combination of the words “Vigor” (which means “power”, “power”) and Niagara Falls, which is recognized as the most powerful waterfall in North America.

Since 1993, long and complex studies have been conducted, the purpose of which was to confirm the unusual properties of Viagra. As a result, it was proved not only high efficiency, but also the safety of tablets in the fight against male erectile dysfunction. As a result, the United States Department of Medicines Control authorized the release of the drug Viagra.viagra generic

How acts Viagra

The main mechanism of action of this drug is a significant increase in blood flow to the penis, which contributes to the appearance of a natural erection in men. Generic Viagra has a positive effect only on the natural mechanisms of erection – this is its novelty and the secret of incredible popularity.
“Viagra” is not a general stimulant that increases male libido, and does not cause the appearance of sexual desire as such – the action of “magic” tablets is based only on local increase of blood flow to the cavernous body of the penis, which contributes to the appearance of an erection.

Reception of Viagra and dose determination.

Usually it is recommended to take one tablet one hour before the planned sexual activity. The drug starts to act somewhere 30-50 minutes after taking and retains its effect for several hours. If you take Viagra before meals, it will work faster. The tablet should be used only when there is an intention and an opportunity to have sexual intercourse, and not more often than once a day.generic viagra pills

Is Viagra compatible for an erection with alcohol?

Taking alcoholic beverages together with Viagra is not prohibited. The question is – how many liquor can be drunk. Alcohol affects the vegetative system, increases the number of contractions of the heart muscle, while the heart enters an active rhythm of work. Generic Viagra for an erection and similar preparations, intensify the process of blood circulation, as a result the heart muscle starts to work even faster. Thus, the heart works with a double load. At such times, the pressure may rise, the headache, the man will feel a general malaise, there will be redness on the face skin and puffiness.
Although many people with low blood pressure, these symptoms do not always appear. Today there are several analogues of Generic Viagra online for strengthening the erection, which act more gently, for example, Viagra Soft. Tablets are not taken orally, but are absorbed. With this kind of medicine, a glass of wine does not affect the health and general condition of the body. On the contrary, the man will relax more and will be able to experience all the delights of intimate life and orgasm. Unequivocally you can say – if a man is going to visit a noisy party, to consume alcohol in large quantities, then it is better to forget about Viagra this evening.
