«Anyone who loves a woman with eyes does not need Viagra» (Valentine Domil)

The original name of this famous product is Sildenafil. The story of this medication begins in Pfizers town (England) in 1992. There were conducted studies, which purpose was to obtain medicine that increases blood flow to heart muscle. But they failed to achieve the desired result.

The most interesting thing happened at the end of trials. The men refused to return remaining drug. They claimed that instead of improving cardiovascular system functioning there was another, equally desired effect – a sharp increase in libido. Employees of large company «Pfizer» have realized that material benefits from pills, increasing potency, production will be much more significant than from cardiac medications, and switched to studying new drug properties.

Viagra’s birthday is March 27, 1998. That same day, the medicine has passed clinical trials and been approved by US Food and Drug Administration (FDA). The public highly appreciated the significance of inventing pills, enhancing erection. The whole team of this unique preparation creators has been awarded with the most important award in the scientific world – the Nobel Prize.

How Do “Blue Pills” Work?

This drug is probably one of the most recognizable in the world. The drug is not available in liquid form. It is only available in 25, 50 or 100 mg gen diamond shape with pills with rounded edges. Initially, Canadian Viagra was prescribed only by doctors, and the necessity to obtain a prescription list stopped many men from such purchase. But even the unwillingness to undergo examinations could not slow down the spread of the drug over the planet. Only during the first year of sales «Pfizer» company earned over a billion dollars. This was an absolute record!

The uniqueness of «magic» pills is that they operate independently of the human psychological state. The result of taking the drug is increased blood flow to reproductive organs, and as consequence, men can perform sexual intercourse.

It is important to know that Viagra does not eliminate disease, which symptom is impotence. Its affect is local and temporary.

Despite the fact that potency booster has become a salvation for men with low erectile function, it is necessary to mention its adverse side effects on the circulatory system. It is proved that Sildenafil inhibits certain proteins synthesis. As a consequence, heart attack risk is significantly increased. According to unofficial data, during the first year of application, there were more than five hundred deaths from overdose. But to indicate heart failure reason was impossible, and «Pfizer» company has not lost a single court trial.

Besides, instructions to the drug indicated that its side effects can be: headaches, dizziness, change in light sensitiveness, impaired consciousness, arrhythmia, nasal stuffiness and even dispersion. And the significant increase of recommended dosage may cause convulsion, nose bleeding, vomiting, eye aches or priapism.

The drug is contraindicated for people with cardiovascular system problems, unstable cardiac angina, arrhythmia and disorders, characterized by bleeding and blood coagulability disorders. It turns out that Viagra is often contraindicated in diseases that cause erectile dysfunction. But fear of heart attack rarely stops men, and deaths are likely to continue.

Information on this drug is at free access, but many people do not want to waste their time to study it. Therefore, Viagra accumulates a huge amount of rumors and myths.
