The Food and Drug Administration said last week that it's considering whether to issue a warning letter for the anti-seizure drug sildenafil, a drug used to treat erectile dysfunction.
The FDA said it's working to review the safety profile of sildenafil, a drug marketed as Viagra and sold under the brand name Revatio. The drug was initially licensed for sale in the United States, but is now sold as Pfizer-owned erectile dysfunction drug Pfizer Viagra.
The FDA has said it plans to issue an electronic petition to the Food and Drug Administration asking the agency to consider whether sildenafil is an appropriate drug for its use in the United States, and whether it should be approved for other uses.
Sildenafil is an inhibitor of the enzyme phosphodiesterase type 5 (PDE5). This enzyme is responsible for the breakdown of certain chemicals that cause erections in the body.
Viagra was approved for use as a treatment for erectile dysfunction in 1998.
It was approved by the FDA in 2003.
In 2010, Viagra sales reached $1.2 billion, up from $0.1 billion in 2009.
In 2010, the drug accounted for about 30 percent of all prescriptions filled by the U. S. population, according to data provided by the company. In the first nine months of 2011, Viagra sales totaled $4.4 billion, up from $3.7 billion in 2009.
Viagra is one of the most prescribed drugs in the U. S., with nearly 2.3 million prescriptions written. The FDA said in a statement the drug is not approved for any other use than as a treatment for erectile dysfunction.
A spokeswoman for Pfizer said the company has no plans to update the drug's labels or issue a warning. But in a statement, Pfizer said the company has made efforts to address the issue and is in discussions with regulators.
In the past, Viagra has been sold as a generic drug under the brand name Revatio, which Pfizer said has helped patients experience erections for about 50 percent of all prescriptions.
Viagra has also helped men with impotence to obtain and keep a penile erection for life. Viagra has also been a drug used to treat erectile dysfunction, although its use in the U. has been limited to treating ED, according to a.
But the FDA said it's considering whether it would issue a warning letter to Pfizer and the company's advertising department for the drug. Viagra is not approved for any other use except to treat ED.
If the FDA's decision is upheld, it will continue to recommend that the FDA consider a similar regulatory pathway, and that the FDA's actions "will be upheld" by the agency, which has taken a step toward that pathway.

But while the FDA is concerned about the growing threat of counterfeit drugs and the growing demand for online services that could be turned into a market for unapproved drugs, the company has said it's doing everything in its power to ensure that its products are used safely and effectively. The company has already spent more than $1 billion on advertising.
