The story of Viagra – The blue pill that changed the world

A happy accident altered the history of mankind. I think the biggest takeaway from the story of Viagra is how Pfizer was able to pivot it's product to solve an issue it was not looking to solve.


1989: 
British Pfizer scientists Peter Dunn and Albert Wood create a drug called sildenafil citrate. produced the drug to treat high blood pressure and angina. The drug is classified as UK-92480.

1991: Dr. Nicholas Terrett, the father of Viagra is named in the British patent for sildenafil citrate, or Viagra as a heart medication.

Early 1990s: Trials of the pill do not yield positive results in treating heart disease. Instead volunteers at the clinical trials all report increased erections days after the trial.

Pfizer pivots and starts running clinical trials in the treatment of erectile dysfunction.

1996: Pfizer patents sildenafil citrate in the United States of America.

1998: The FDA approves of the drug and within weeks over 40,000 prescriptions are handed out by doctors around the USA.

1998-2020: Viagra, generic alternatives, competitors like Cialis and Levitra have improved the lives of hundreds of millions of men around the world.

This is the 22 year history of the ED drug that has changed sex forever. We've also shared some stories of the people who have taken Viagra.
