What is Viagra?
The microbiologist and immunologist Louis Pasteur said that any scientific discovery is, first of all, a happy event, and only then - intellect and knowledge. He also noted that the presented happy opportunity still needs to be able to use it wisely. The history of Viagra is an example of an excellent combination of chance and resourcefulness of researchers.
"Unsuccessful" experiment
Unremarkable English company Pfizer International Inc in 1992 set out to develop a new medicine for angina pectoris. In the laboratory, the substance sildenafil citrate was synthesized. Scientists hoped that this drug will increase blood supply to the heart muscle, dilate the blood vessels, lower blood pressure.
To participate in the experiment, a group of women and men was collected. The effect recorded by the researchers was strikingly different from the one expected. The drug did not live up to expectations, did not affect the heart's blood supply, did not relieve angina attacks. But for some reason the male part of the "experimental" did not wish to part with the medicine after the completion of the experiment. The solution was simple: after its reception, the subjects felt an unusual increase in sexual forces - a strong rush of blood to the penis and a subsequent powerful erection.
Resourceful scientists showed a business grasp, realizing that an unexpected effect can be profitable to use. A loud invasion of the mass consumption arena was preceded by 5 years of experimental research. To introduce the invention on the market, about $ 500 million was spent at the preparatory stage. The new drug was named "Viagra", and lucky scientists in 1998 received a well-deserved award - the Nobel Prize.
Viagra - waterfall of love
An entertaining story is connected with the origin of the name. Vigor - energy, power. The power of sildenafil was so shocking that the scientists compared it to Niagara. From a combination of these two words - vigor and Niagara - "Viagra" was born.
The discovery of Viagra is a real revolution in the field of sexual problems. The drug, which increases the flow of blood to the genitals and prolongs the erection, has saved more than one family. Prior to this, erectile dysfunction was fought with the help of injections, implants. Similar Viagra drugs( which could be taken orally) did not exist. The tablet, which strengthens the potency, produced an explosion in the minds of millions of people.
Today there are many analogues of Viagra, but the ancestor not only does not lose its positions, but every year finds new friends.
Using the drug before a romantic appointment, it is necessary to remember about contraindications. Reception of a magic tablet is forbidden at the use of medicines with nitrates. Otherwise, the meeting may end in intensive care.
