Goa, India - A new research study shows that men with erectile dysfunction (ED) may benefit more from Viagra than those not on the medication.
The study, which was conducted in the US, was published in theJournal of Sexual Medicine.
A total of 12,008 men between the ages of 40 and 70 with erectile dysfunction who were not taking Viagra were randomly assigned to take one of three treatments: a placebo pill or a treatment containing a placebo. The researchers then compared the results to those of a similar group who received a similar number of Viagra pills.
The researchers found that the study participants had improved erectile function in a more significant manner with treatment.
The researchers concluded that men taking Viagra in the study had a 50 percent longer time to have an erection than those not taking the medication.
A study of Viagra treatment in the US could help to improve the lives of millions of people, the study authors wrote.
Viagra is a type of medicine called a phosphodiesterase type 5 (PDE5) inhibitor. When a man has an erection he uses an enzyme called PDE5 to make nitric oxide, a chemical that relaxes the muscles in the penis, allowing blood to flow into the penis.
But when a man has trouble getting an erection, the PDE5 breaks down the chemical into two molecules, called cyclic guanosine monophosphate (cGMP), that then relax the muscles in the penis and cause blood to flow into it.
This helps men with ED get and keep an erection, and can also help a man with other conditions, such as high blood pressure, high cholesterol, diabetes, or heart disease.
There are two main types of PDE5 inhibitors: sildenafil and vardenafil. Viagra is a type of medicine known as a PDE5 inhibitor, and is also known by its generic name sildenafil.
Both Viagra and vardenafil are sold under the brand names Stendra and Levitra. They work by blocking a specific enzyme in the body called PDE5.
