Scientists Develop New-Gen Anti-Impotency Drug Based on Nanoparticles


Soon we could witness the appearance of new generation of drugs that treat erectile dysfunction. These drugs will be based on nanoparticles.

Scientists working at the Albert Einstein College of Medicine in New York managed to find a new application for drug featuring nanoparticles as the main treatment for impotency. They presented their revolutionary discovery at the 104th Annual Meeting of the American Urological Association.

Researches used nanoparticles as a sole sustained release drug delivery instrument. These nanoparticles are created of a hybrid hydrogel/glass capsule that includes a nitric oxide.

The nitric oxide, which is used in erection biology, aids in relaxing smooth muscle cells. To note that NO occurs naturally in the human body in order to aid expand blood vessels, helping them load with blood, informs

Researchers carried out their experiments on rats where 71 percent of rats tested registered positive effects after being applied nanoparticles on top of the penis' skin. According to scientists, their topical treatment is likely to show fewer side effects than the popular anti-impotence drug Viagra, which is known to cause headaches and facial flushing. In addition, they say that the new nanoparticle treatment could have a much faster effect than Viagra.

Commenting on the new way of treating erectyle dysfunction Ira D. Sharlip, MD, informed that it could prove to bring a revolution in the field, but it still "remains to be seen whether the effect of the nanoparticle technology is a local or a systemic effect." According to Dr. Sharlip, the nanoparticle treatment can also be used to treat other conditions, including premature ejaculation, currently present in 20-30 percent of men.
