Viagra

Erectile dysfunction is one of the most common diseases among men. It is the difficulty of achieving an erection or of maintaining it for a sufficient time to have a sexual encounter.

It is also called impotence and occurs when the penis does not receive enough blood and therefore does not have the ability to put the penis upright. This does not mean that the man in question has no desire with the partner or partner of sexual relations.

It is a disease that affects about 30 million Americans and can manifest itself in two ways: every time you try to have a sexual relationship, or once in a while. Studies estimate that about 50% of men aged 35 to 40 suffer from erectile dysfunction.

Original Viagra

Viagra or Sildenafil nitrate, developed by British scientists and marketed primarily by pharmaceutical Pfizer, is a drug used to treat this problem where blood does not reach the penis properly. It works for about 4 hours and that is why it should be ingested just before a sexual encounter.

Although it seems hard to believe, viagra was initially created to treat high blood pressure angina. However, the drug had a very small effect on angina, but significantly induced penile erections.

That’s why the Pfizer company started marketing in 1998, solely and exclusively to treat the problem of erectile dysfunction. Its success is such that the sales recorded between 1999 and 2001 exceed one billion dollars.

How does Viagra work?

When a man is excited, the tissues of the penis tend to relax and the blood normally flows towards him, causing an erection. For those who do not reach it naturally, Viagra increases the release of chemicals that relax these tissues and the adjacent area.

In addition to increasing the size of the penis, Viagra also achieves that the male virile member reaches a state of rigidity of 95%. This represents 5% more than usual 90% that a healthy man naturally gets.

On the other hand, recovery after sexual intercourse is achieved much more quickly. The period of time from ejaculation until it is ready to copulate again is abbreviated.

Although it is common to buy it on pharmacy shelves and buy it without a prescription, it is best to always consult a specialist before consuming it as it can cause some side effects in some patients.

In most cases it is best to take a single dose of Viagra in a 50-milligram presentation, at least 30 minutes before having sex. Depending on its efficacy, the dose may be increased up to a maximum of 100 mg or reduced to 25 mg.

However, its maximum effect will be reached even one hour after it has been consumed. And that’s why there is also a chewable form whose effects start to show only a quarter of an hour (15 minutes) after the shot.

Some advices

It is important to underline that the effectiveness of Viagra also depends on the previous stimulation received. That is, men who suffer from erectile dysfunction or who use Viagra to achieve greater satisfaction during sex will not get an erection simply by taking the blue pill.
Do not do things quickly because they never work well. Viagra takes effect between 30-60 minutes after ingestion, can be taken up to 4 hours before sexual intercourse and provides better results combined with an environment that promotes excitement.
