How Viagra and Its Generics Were Created?

How Was Viagra Created?

Viagra was invented by chance as the treatment of erectile dysfunction. Pharmacological company “Pfizer” tested Sildenafil Citrate which supposed to be used to treat patients with cardiac dysfunction.

According to expectations, Sildenafil due to the blood flow to the cardiac muscle had to lower blood pressure. But this effect was not achieved. But there was a relaxation of the muscles blocking the blood flow to the penis, which provides a natural erection in case of sexual excitement presence. The new drug was named, referring to the large waterfall of North America “Niagara” and “vigor”, indicating power, strength, energy.
