A new study suggests that the anti-Viagra pill might lead to erectile dysfunction.
The study, published Monday in theJournal of the American Urological Association, was funded by Pfizer Inc. and was led by Dr. Irwin Goldstein, who is a consultant for Pfizer.
The researchers tested the blood-flow to the penis in patients who took the new anti-Viagra pills, which included sildenafil (sold under the brand name Viagra), and tadalafil (sold under the brand name Cialis), two drugs approved to treat erectile dysfunction. In the study, participants were asked to rate the intensity of sexual activity they enjoyed on a scale of 1 to 10. A higher score led to a stronger sense of sexual performance, but not for erectile dysfunction.
Dr. Goldstein, who is co-director of the University of Chicago's Sexual Medicine and Surgery Center, and co-author of the study, said the results are consistent with previous research that showed that sildenafil and tadalafil led to erectile dysfunction in a significant number of men.
"In the studies we found that participants who took the new drug experienced a significant increase in sexual activity compared to those who were not taking the drug," he said. "We found that the most common side effects of the drugs were erectile dysfunction and sexual dysfunction."
Goldstein said the new findings suggest that a new class of drugs could be an important treatment for patients with erectile dysfunction who are at high risk of developing the condition.
In the study, he said, "We found a significant association between the use of sildenafil and erectile dysfunction."
However, the researchers did not find an association between the use of tadalafil and erectile dysfunction.
The new study was presented at the 2012 Urology Conference, held in San Antonio, Texas, where Dr. Goldstein said that he was impressed by the results.
"It's an interesting study," said Dr. Goldstein, who is also the director of the University of Chicago Sexual Medicine and Surgery Center.
"There is a lot of interest in the idea that Viagra and Cialis help men with erectile dysfunction. We do know there is a connection. I think that there's a lot of interest in the idea that Viagra and Cialis are good for men with erectile dysfunction, but we're not sure that that is true," he said.
Goldstein, who is also the co-author of the study, said he believes the study is important because it demonstrates the potential for the drug to be effective in treating erectile dysfunction in men.
He said that while the study is reassuring, it will take several years to get to the bottom of the drug's effects and the study's results are not expected to become widely disseminated.
In a separate study, researchers compared the effects of sildenafil, the brand name for Viagra, and tadalafil, the brand name for Cialis, on patients who took the drugs for an average of 18 months.
The researchers found that patients who took the drugs reported a decrease in their erections and an increase in the severity of sexual intercourse. They also found that participants who took the drugs also experienced a decrease in the frequency of their erections.
Goldstein said he hopes the findings will encourage more people to seek help for their erectile dysfunction and encourage them to take the drugs more frequently.
He said that while the study is reassuring, it also shows that a new class of drugs may be an important treatment for patients with erectile dysfunction.
