VIAGRA TURNS 20

Viagra®, the little blue pill that’s helped millions of men worldwide, has turned 20. But its origins go a little further back than that…. 

It was 1991 and pharmaceutical company Pfizer was testing sildenafil citrate for its potential ability to lower blood pressure.  Male participants in the study kept noting in their reports of side effects that the drug “raised something else” thus earning it the nickname “the Pfizer riser”.  Pfizer then changed course, focusing of the development of sildenafil for male erection difficulties instead.

 By March 27, 1998, the US Food and Drug Administration gave Pfizer’s new drug, now named Viagra®, the green light.  There was an immediate demand and 150,000 prescriptions were written in the first two weeks.1 Nearly 200,000 being written each week shortly after that.  Viagra® has now been used by over 65 million men worldwide2.
