Pfizer, which sells generic versions of Viagra and other prescription-only medications, is the biggest manufacturer of the drugs it sells. Pfizer has spent nearly $6 billion on generic drugs since it launched its drug, the company that invented Viagra in 1998. Pfizer also manufactures Viagra and other drugs in other countries.
Pfizer's sales have grown in recent years, as it has more than a decade since the first FDA-approved drugs in the world first became available. And it still has the drug's patent expiring in 2024. But it's still the largest manufacturer of prescription drugs, with more than a decade of sales before it will make generic Viagra available to Americans.
The company said it has taken some steps to reduce its share of the pharmaceutical market. In December last year, the company announced that its patent for Viagra, the most popular prescription drug used to treat erectile dysfunction, had expired. It also announced that it had reached an agreement with Pfizer to sell the drug as a "generally accepted and safe" drug for the treatment of erectile dysfunction. In other words, Viagra is the best-known drug for treating impotence, or erectile dysfunction.
Pfizer's patent on Viagra expired on July 1, 2017, and its patent on the drug expires in 2024. That means that Pfizer is now selling a generic version of Viagra, and its prices have risen sharply to what it was in 1998, the year Pfizer started selling the drug.
Pfizer said the generic version will be sold in the United States through its online pharmacy, but it's not clear that the company will sell the other drugs in the U. S. that it will make available on a regular basis. Pfizer's website did not return calls seeking comment.
Viagra is still the most popular drug in the world. The U. Food and Drug Administration approved Viagra in 1998 for male impotence. Viagra has been marketed to American men for centuries, but it has also become one of the most popular prescription medications.
The FDA approved Viagra to treat erectile dysfunction in 1998, and it has been around for years. Viagra was the first drug approved by the FDA to treat erectile dysfunction since a man's first sexual experience began in 1877. The drug is called sildenafil, and it was approved by the FDA in 1998.
Viagra's patent expired in 2024, meaning it will be sold only on the FDA's website. In the United States, Pfizer will sell Viagra only on its website. The generic version is sold as a generic drug under the brand name Cialis.
