A new research suggests that the drug Viagra might be able to help treat erectile dysfunction.
Viagra was originally developed as a treatment for angina. However, researchers at the University of New South Wales and the University of Washington in Australia were testing the drug in a laboratory setting.
Viagra is the second-most-prescribed drug to treat erectile dysfunction. In March, researchers led by chemist Richard G. Korniloff reported that a drug that could increase the blood flow to the penis and alleviate symptoms like trouble getting or keeping an erection, would be able to treat erectile dysfunction.
Viagra, also known by the generic name sildenafil citrate, was first tested for its effect in the early 1990s. Its effectiveness was initially thought to be caused by a drug called angina, which was then thought to be caused by the nitrates (which are often found in some recreational drugs) found in prescription drugs such as heroin and cocaine.
Korniloff, who is a professor at the University of Washington, said the research has found that Viagra could improve blood flow to the penis. However, Korniloff and his colleagues had found that Viagra would not increase the blood flow to the penis.
Viagra was originally developed as an anti-depressant and was shown to inhibit the production of cyclic guanosine monophosphate (cGMP). However, researchers found that the drug could also inhibit the activity of the enzyme called protein kinase A (PKA).
The researchers used blood samples from men taking Viagra to demonstrate that the drug caused an increase in blood flow to the penis. The researchers then tested the blood flow to the penis after sildenafil, another PKA inhibitor, was added to the mix. The results were not unexpected.
Viagra was originally tested for its effects in animals. It has since been used as a treatment for erectile dysfunction and is thought to have a positive effect on the development of the male genitals in rats. In humans, it is used to treat erectile dysfunction.
“While the study does not prove that Viagra increases blood flow to the penis, it does suggest that Viagra may be a potential treatment for erectile dysfunction,” said Korniloff.
Viagra is the brand name for the drug sildenafil citrate, which is sold under the generic name tadalafil. The drug is available in several generic forms such as Viagra Connect, and is not approved for the treatment of erectile dysfunction. However, the drug may still be able to improve the function of the penile arteries in patients with erectile dysfunction.
The New England Journal of Medicine () published a summary of Korniloff’s findings in the New England Journal of Medicine in September 2023.Korniloff and his team found that a single dose of Viagra (10 mg) significantly improved erectile function in men with erectile dysfunction. This study found that a single dose of Viagra (20 mg) improved the ability of men to achieve an erection.
Korniloff and his colleagues used a clinical trial protocol to test whether Viagra could be beneficial for erectile dysfunction. They were recruited from the Australian Research Council for funding to conduct the trial.
The researchers recruited 100 healthy volunteers from the Australian Research Council for health research, with the first session lasting about two hours. All the volunteers were administered sildenafil (25 mg) one hour before planned sexual activity, and sexual activity was planned on the second and third days of each study period.
Viagra was originally designed to treat angina but was later discovered to be a treatment for angina pectoris (chest pain) in the 1960s.
The researchers also conducted a randomized, double-blind, placebo-controlled trial in which Viagra was administered to men with erectile dysfunction and healthy volunteers. The men in the placebo group took sildenafil (25 mg) one hour before planned sexual activity.
Sildenafil (Viagra Connect) is the brand name for tadalafil. The researchers recruited men who had been diagnosed with erectile dysfunction. They then administered sildenafil (Viagra) to the men in the placebo group.

Viagra (sildenafil) is used to treat erectile dysfunction. Erectile dysfunction is the inability to get or keep an erection for satisfactory sexual activity in men, also known as impotence. Sildenafil belongs to a class of medications called phosphodiesterase type5 (PDE5) inhibitors. Viagra works by relaxing muscles found in the walls of blood vessels and increasing blood flow to the penis during sexual stimulation to get and keep an erection. Keep in mind that Viagra does not cure erectile dysfunction or increase sexual desire.
