Introduction to Pfizer and Viagra

Pfizer, a multinational pharmaceutical corporation, owns the brand name Viagra. Viagra, often referred to as the "little blue pill," has gained immense popularity for the treatment of erectile dysfunction (ED). This groundbreaking erectile dysfunction drug hit the market in 1998, forever changing the landscape of sexual health medication.

Explanation of Viagra's use for erectile dysfunction

Viagra is specifically designed to treat erectile dysfunction.

The active ingredient in Viagra is sildenafil citrate, a substance that also forms the basis for other ED treatments.Viagra works by increasing blood flow to the penis, which facilitates an erection in response to sexual stimulation.Over 30 million prescriptions have been dispensed for Viagra in 120 countries, reflecting its widespread use and acceptance.

FDA approval of Viagra in 1998

The U.S. Food and Drug Administration (FDA) approved Viagra for the treatment of erectile dysfunction in 1998. This decision followed rigorous clinical trials and scientific scrutiny, ensuring the safety and effectiveness of the drug for its intended use. The approval of Viagra marked a significant milestone in ED treatment, offering millions of men a new therapeutic option.

Pfizer's exclusive rights to Viagra for almost 20 years

Pfizer Inc. held exclusive rights to the brand-name erectile dysfunction drug Viagra for almost 20 years. This period of exclusivity allowed Pfizer to capitalize on the success and popularity of Viagra, establishing it as a leading treatment for ED across the globe. During this time, Pfizer was the sole provider of this revolutionary drug.

Settlement between Pfizer and Teva Pharmaceuticals in 2013

The landscape changed in 2013 when Pfizer reached a settlement with Teva Pharmaceuticals. This agreement allowed Teva Pharmaceuticals to start manufacturing a generic version of Viagra. As the first company to produce generic Viagra, Teva introduced a more affordable alternative to the brand-name drug.

Introduction of a generic version of Viagra

In December 2017, the first generic version of Viagra was launched. Generic Viagra, or sildenafil citrate, works identically to Viagra but at a lower cost. While Pfizer continues to manufacture the brand-name drug, other companies, both globally and in the United States, now produce sildenafil. This has increased access to the drug for many men, providing an effective treatment for ED at a more affordable price.
