Pfizer, the pharmaceutical giant, has launched a controversial erectile dysfunction drug, Viagra, to be sold under a generic version in China.
Pfizer said Thursday that it had received a "solicited" letter from the US Food and Drug Administration (FDA) requesting that the drug be approved for sale in the country and that it be made available exclusively to consumers in the United States.
"We are pleased to announce that Pfizer has received a letter from the FDA requesting that the Viagra product be made available exclusively to Americans in the United States," said John Lechleiter, Pfizer's president and CEO. "Pfizer has been working with the FDA for some time to make Viagra available to American consumers in the United States and is continuing to work with them to seek approval for its generic product."
The letter, which was sent Friday to Pfizer, included the following statement:
"We are pleased to announce that Pfizer has received a letter from the FDA requesting that the Viagra product be made available exclusively to American consumers in the United States and is making available in China, a country with the highest prevalence of erectile dysfunction in China. Pfizer has been working with the FDA for some time to make Viagra available to American consumers in the United States and is continuing to work with them to seek approval for its generic product."
Pfizer had said that the drug was approved for sale in Australia and has been sold in the United States for many years.
"The FDA has asked Pfizer to review the safety and effectiveness of the Viagra, as well as the potential for side effects associated with the drug," Pfizer said in a statement.
The FDA said that Pfizer has received "solicited" letters from physicians in Australia and New Zealand and from pharmaceutical companies in the United States and New Zealand. The letters indicate that the drug is being reviewed for safety and effectiveness in Australia.
Pfizer's patent has expired in several countries including the United Kingdom, the Netherlands and Germany.
The letter was sent Friday to Pfizer by Pfizer's American and New Zealand subsidiary, Pfizer Pharmaceuticals Inc.

The U. S. Food and Drug Administration said Friday it will require doctors to submit a prescription drug list to make sure it is safe for patients, particularly those who need it most. The drug labeling for Viagra, for example, will be updated to include information about the drug's risks and benefits, including potential side effects. The agency also announced it was considering possible changes to the labeling for another form of the drug, which is not currently on the FDA's list of safe drugs.
Viagra, the active ingredient in Levitra, is a drug used to treat erectile dysfunction in men. It is available by prescription only, but doctors can suggest it if it is deemed unsafe for patients. The drug is also known by the brand name Adcirca, or Adderall. The agency will require physicians to submit a drug list containing the active ingredient in Viagra. The drug labeling for Adcirca is expected to be updated to include information about the drug's risks and benefits, including potential side effects, including erectile dysfunction. Viagra, the prescription-only drug for erectile dysfunction, is sold by prescription only and is a part of the family of medications known as phosphodiesterase type 5 (PDE5) inhibitors, which are used to treat erectile dysfunction in men. Doctors generally prescribe Viagra to treat erectile dysfunction in men, but patients may be prescribed other medications to treat the condition. The agency will only allow doctors to submit a drug list containing the active ingredient in Viagra if the physician has already prescribed the drug or is considering other treatment options for the condition.
"The FDA is working closely with the pharmaceutical industry and other regulators to ensure the safety and effectiveness of all new drugs on the market. But it's important to emphasize that patients should not rely on the drug labels to determine if it's safe for them," said Dr. Steven Nissen, chairman and chief executive of the American Society of Health-System Pharmacists. "The FDA is committed to improving patient safety, and we will continue to work with pharmaceutical companies to ensure that all medications we prescribe are safe and effective for the treatment of erectile dysfunction."
The FDA has not yet issued a public statement on the matter, but Nissen said he believes the agency's work is progressing.
In February, the U. Food and Drug Administration announced it was investigating an incident involving a patient who took the drug after he was prescribed it for erectile dysfunction. A patient told investigators she was taking the drug for an eye problem that caused her to be put on a steroid patch. She was put on a steroid patch about an hour after she stopped taking the drug, according to the FDA.
The patient was brought to the hospital after an overdose and given a prescription for Viagra, but he took a steroid patch instead. When he arrived at the hospital, he was found to have erectile dysfunction and had an erection that lasted over four hours, the FDA said.
The FDA said it was not aware of any previous cases of sexual dysfunction that occurred with Viagra. But the agency said it has found no cases of erectile dysfunction in patients who take the drug.
The FDA did not respond to a request for comment. The agency also said it is considering a new drug application for Viagra in the same class of drugs. The application could be submitted before the end of the year, according to the FDA.
In June, the Food and Drug Administration announced it was considering a revised labeling for Viagra, the drug used to treat erectile dysfunction. The drug label for Viagra is expected to be updated to include information about the drug's risks and benefits, including potential side effects. The FDA will not have until August to submit the application, but it may be possible that a drug application can be submitted soon after.
The agency also said it is considering a revised version of its drug labeling for the prescription-only drug Cialis. The drug labeling for Cialis will also be updated to include information about its benefits and risks.
The agency has not announced a decision about the timing of the agency's decision, but the drug company Pfizer is seeking to increase its sales to more than $1 billion in the United States. The drug is a form of PDE5 inhibitor, which is used to treat erectile dysfunction, the FDA said. The drug's labeling for Cialis has been updated to include information about its benefits and risks. The agency will not have until August to submit the application, but it may be possible that a drug application can be submitted soon after.
