The first in the world to win a patent-protected medical device patent is Pfizer Inc.’s Viagra, a drug for erectile dysfunction that has since been introduced by the US pharmaceutical industry and is being sold in other countries.
Pfizer Inc. has already been making generic Viagra available to the public under the generic name of Sildenafil.
In August 1998, the Food and Drug Administration granted Pfizer Inc.’s patent on sildenafil for the treatment of erectile dysfunction in men. The drug was then developed by Eli Lilly, which was developing sildenafil by accident, and has been named Viagra by Pfizer in the US patent for the treatment of erectile dysfunction.
Viagra, which is available by prescription only, is a type of medication known as a phosphodiesterase-5 (PDE5) inhibitor. Pfizer’s Viagra is available only with a prescription, so it’s important to be aware of the potential for misuse and side effects. It is also recommended to avoid taking the medication in high doses, as the drug may not work as well.
Pfizer has been working with several pharmaceutical companies to develop the drug for the treatment of pulmonary arterial hypertension, the most common form of cardiovascular disease.

Pfizer filed the patent application in July, 1999, and is awaiting the FDA approval for its generic version of Viagra.

However, these side effects are uncommon in the general population. In fact, Viagra is the only PDE5 inhibitor approved for the treatment of ED, and there have been reports of rare side effects such as fainting and vision problems in patients taking Viagra.
