The full name of Viagra is Viagra, and the chemical name is sildenafil. The mechanism of Viagra is to inhibit the activity of type 5 phosphodiesterase in human body, and then stimulate the release of nitric oxide in human body, so that smooth muscle cells relax and blood vessels relax, and then relax the smooth muscle of corpus cavernosum, increase the degree of erection, and treat erectile dysfunction (ED). The clinical application effect is good.
From its mechanism of action, it is like widening the ear canal and making the blood supply of the penis more adequate, rather than increasing sexual excitement by affecting the central nervous system. Therefore, Viagra is neither an aphrodisiac nor an aphrodisiac. Taking medicine as required is not addictive.
