Effects of Viagra Sildenafil

Millions of men suffer from erectile dysfunction in silence. Most of them are not comfortable discussing their condition openly due to stigmatization. Use of pills, especially Viagra Sildenafil, is a solution that many people cherish. The medicine helps improve the erection from sexual stimulation. Note that this drug only works best when there is some sexual stimulation. The partners should therefore not skip any part of love making simply because they are using Viagra Sildenafil because the medicine may not really work in such situations.

When sexually stimulated, the body's nervous system releases nitric oxide into the penis erectile tissue, which triggers an enzyme responsible for the production of messenger cyclic guanosine monophosphate (cGMP). cGMP then leads to the dilation of the penile arteries, making them fill with blood and eventually resulting in an erection. Viagra ensure that cGMP doesn't degrade, keeping the blood vessels dilated, more blood flowing into the penile arteries and therefore keeping and sustaining the erection during intercourse.

Note that most of the rare side effects discussed are less likely to affect healthy users of the drug but those with underlying medical conditions, such as hypertension, heart disease, high cholesterol, diabetes, or already existing eye complications. Even though some cases of vision loss have been reported, it hasn't been possible to directly link it to Viagra use.
