Breaking into the light from the depths of scientific laboratories of the pharmaceutical giant Pfizer Inc in 1998, a small blue tablet quickly conquered the world. Still - a cure was a real revolution in the treatment of impotence: a man with erectile dysfunction has drunk the miraculous pill, and the problems vanished, he is - the hero-lover!

Recently, the drug has been produced not only in the form of tablets. Already you can buy Generic Viagra 100 mg - spray that can be injected into the nasal passages.What is the mechanism of actionThe mechanism of action of the drug is very popular is simple: because of normal nitric oxide increased blood flow to the penis of men. The result comes almost natural erection. After completion of sexual intercourse, it is naturally the same stops. Medication gives only a temporary effect, it can not cure impotence once and for all.Erections resulting dosing appears not by itself, but only at the moment of sexual arousal. The drug is not in a position to affect the libido, if there is no desire, it will not help. Do not save a miracle pill, and in some severe cases, when thoroughly disrupted physiology of the penis. However, according to opinion polls, 7 and 10, and men do a good job preparation. The respondents reported not only to strengthen erections, but also more vivid sexual feelings. They tied it with just taking medication. Of course, it is possible that these results are caused not only physiological, but also psychological reasons. That is not only one of the drugs effectiveness, but also the excitement that exists around it.
In what cases to take
Viagra is a medicine for the elimination of erectile dysfunction. That is, in order to take it, it is necessary for at least the data to diagnose disorders. Experts define erectile dysfunction as a "pathological condition which reduces the quality of erections in men and as a result, comes the impossibility of full sexual intercourse."Usually such trouble happens to men after 40 years. However, the recent erection problems arise in very young people . Abroad erectile disorder - a common phenomenon. For example, a survey of men Massachusetts, sociologists found that 52% of respondents have problems with erection.

Doctors do not claim that the miracle pill was the direct cause of these deaths. However, Reuters reports that death from cardiovascular failure occurred immediately after taking this medication.
