A new study has shown that the drug used to treat erectile dysfunction is also safe. According to the American Heart Association, the drug was the first approved by the FDA to treat erectile dysfunction, and is the most common treatment for ED, in 2023. It is currently available in more than 250 countries around the world. The study, conducted by researchers at Hong Kong-based Stanford University School of Medicine, was published in the journal Circulation.
The research is part of a larger study funded by the National Heart, Lung and Blood Institute. The study was led by a team of scientists led by Dr. Yoo Hong, professor of cardiology at Stanford University and director of Stanford’s Cardiovascular Clinic. They recruited more than 4,300 men who had been diagnosed with ED using the International Index of Erectile Function (IIEF) to measure their ability to achieve and maintain an erection. The study was designed to test the drug’s safety in the men who used it.
In the study, the researchers tested the drug’s efficacy in the men who took it for 4 weeks. They used data from the large international clinical trials that have taken place since 2002, and examined the drugs’ side effects in the men who took them. The results showed that it did not cause any side effects in the men who took it. They also found that the men who took it for 4 weeks were more likely to have a lower incidence of side effects than those who took it for a longer time.
“The safety of sildenafil citrate (Viagra) has been well established for several decades,” said Dr. Yoo Hong, professor of cardiology and director of the Stanford Department of Medicine. “This is the first study that has shown that sildenafil citrate is safe and effective for treating erectile dysfunction.”
Viagra was originally approved by the FDA for erectile dysfunction in 1998. It was the first medication approved by the FDA to treat ED and the first drug to treat both erectile dysfunction and benign prostatic hyperplasia. The drug’s effectiveness was based on its ability to block PDE5, which is a type of enzyme that degrades cGMP, a chemical that causes erections. Viagra works by increasing blood flow to the penis and allowing for firmer erections when the man is sexually excited.
The study found that men who took sildenafil citrate for 4 weeks experienced a significantly lower incidence of side effects than men who took it for a longer time, although there were no statistically significant differences in side effects between the groups. The researchers also found that men who took sildenafil citrate for 4 weeks were more likely to have a lower incidence of side effects, although there were no statistically significant differences in side effects between the groups.
Researchers said they believe the results are particularly encouraging. They noted that sildenafil citrate was well tolerated, and that side effects were less likely with use. Viagra is only approved for men with ED but not for benign prostatic hyperplasia, so it is important to monitor men for side effects.
The study was published in Circulation. The study is the first that has compared the safety of sildenafil citrate and sildenafil in a large international clinical trial. The results were published in the journal Circulation.

The researchers also looked at sildenafil citrate, the active ingredient in Viagra. They also looked at men who used sildenafil citrate for a month or more, and then again for four weeks.
“Sildenafil citrate is a safe and effective medication for many men, but it may not be appropriate for men with certain health conditions,” said Dr. Yoo Hong, professor of cardiology and director of Stanford’s Department of Medicine. “This study shows that sildenafil citrate is not effective in treating erectile dysfunction in men with certain health conditions, such as diabetes or high blood pressure.”
The drug is available only by prescription.
