Pfizer's blockbuster erectile dysfunction drug Cialis, once hailed as a miracle drug for the nation, has been rejected twice by health officials, who warned it could be linked to possible drug maker safety issues.
The warning comes after health officials said the drug, which is the most widely prescribed drug for impotence, is linked to the death of one man's penis when it was taken by a doctor.
It is the first time a drug company has been warned to take a PDE5 inhibitor.
The warning was issued Tuesday after the Food and Drug Administration issued a black box warning about the drug, which is a PDE5 inhibitor used to treat erectile dysfunction.
The drug was approved in the United States in December 2006, but was rejected twice, the FDA said in a statement. It is the most widely prescribed drug for impotence in the world, and is widely used by doctors to treat erectile dysfunction.
Pfizer is the world's largest maker of prescription drugs, accounting for more than 30 percent of the global sales of the drug, according to a research firm.
The drug, which is manufactured by Lilly, is marketed as a generic version of Pfizer Inc.'s Viagra, which is sold by Eli Lilly Co.
It is the second drug to be recalled after Cialis, which was approved by the FDA in 2003, was approved in the U. S. in 2006. The drug, which was developed by AstraZeneca, is manufactured by Eli Lilly, the maker of Cialis.
The warning was issued after Cialis was approved in the U. in December 2006, and the maker of Viagra, which is sold by Pfizer, said it would continue to market the drug for the U.
The warning is the latest of the many marketing issues involving the drug, one of which was the failure of the company to disclose the results of a clinical trial, in which the drug's efficacy was linked to side effects.
But the FDA said the company could not disclose the results of the trial.
Lilly said it would continue to market the drug for the U. market.
The company has been criticized for failing to disclose the results of the trial because Lilly said it was "somewhat disappointed with the FDA's conclusion."
The FDA said it was disappointed with the results of the clinical trial.
A spokeswoman said in a statement that the company "continues to follow the lead of physicians and is committed to providing safe and effective treatment for men with erectile dysfunction" and the company was "reviewing all available information on the safety and efficacy of this medication."
The company did not immediately return a messages from NPR about the results of the clinical trial. A spokesperson for Pfizer declined to comment.
The company had been seeking information about the results of the trial through a spokeswoman for Pfizer.

The drug's approval was due to a "black box warning" that it could lead to a sudden and potentially dangerous fall in blood pressure that could lead to fainting, a warning about heart attacks and strokes was added.
The warning was issued at the beginning of June and has been repeated since.
In December, the FDA said it had received "more than 1,000 reports" of possible side effects of the drug, which were "reported to be related to the drug and the use of other drugs."
In a statement, the company said: "This is the first warning for the use of any medicine that is intended to prevent or treat certain diseases or conditions. In the United States, this is known as the "black box warning."
The company had been looking for a way to "satisfy" that this warning was applicable.
The company has been asked to update its drug labels and submit the results of a clinical trial to the FDA.
A spokesman for Lilly, Bayer, said it "continues to follow the advice and has no plans to delay further actions.
