HONOLULAN, N. J.- After months of uncertainty due to patent expirations, the U. S. Patent and Trademark Office announced Monday that it would start selling generic versions of Viagra and similar drugs. The news comes after an online forum of doctors and pharmacists reported that an FDA-approved drug is being promoted as being "better for the patient than a Viagra or similar drug."
The move follows an FDA advisory committee meeting in July that recommended that the drug be marketed as "the first line of treatment for erectile dysfunction" and would only be available with a prescription.
The advisory committee also recommended that drug companies and regulatory agencies be careful about misleading consumers about generic drugs. The committee also recommended that the FDA ensure that any drugs for erectile dysfunction that have been approved for sale are safe to use.
In its statement, the FDA said that it has "no reason to believe" that the drugmaker will continue selling it generic versions of the prescription-strength medication. In a statement, it did not say if the company is selling the drugs "in violation of the Federal Food, Drug and Cosmetic Act," but said the company has no plans to sell the drugs.
In a statement, Pfizer Inc., the parent of Eli Lilly & Co., said that it has received numerous inquiries from consumers about the product, and that it believes that its marketing efforts have been "not only disappointing but also unprofessional."
Pfizer said that it "further confirms" that the company is aware of its concerns about the FDA's approval of Viagra and other drugs for erectile dysfunction and that the company has not sought to identify any misleading advertisements.
"We are committed to maintaining an open and candid dialogue with consumers about their health, and in doing so, we will work to find out what the appropriate information about Viagra and the other drugs that we consider to be safe and effective in treating erectile dysfunction," Pfizer said. "While our research has not shown significant benefit to the overall health of the population, we believe that the safety profile of Viagra is a top priority for Pfizer."
In a statement, the company said that its "reconciliation with regulatory authorities" in regard to Viagra was "very clear" and that "Viagra is a safe medicine that we are committed to promoting."
The company said that it will "continue to work closely with the FDA to develop a regulatory pathway for consumers to safely obtain Viagra and to inform the public about the safety and efficacy of the drug."
In a statement, Pfizer said that it was "not surprised" by the FDA's decision, noting that it was aware of Pfizer's concerns regarding Viagra and its efficacy in treating erectile dysfunction.The company noted that its "full financial guidance is in place."
In a statement, the company said that its "full financial guidance is in place."A spokeswoman for Pfizer said that it "entleheartedly disagrees" with the decision, noting that the company has had "very good relations" with the FDA. "We take great satisfaction in the overall relationship between Pfizer and the FDA and have taken great pains to ensure that they comply with our obligations to the FDA," she said. "We will continue to work closely with the FDA to ensure that this guidance is followed."
Pfizer shares rose 6.4 percent in after-hours trading, helped by the news.
