How Viagra works?

The active ingredient in Viagra is Sildenafil. After ingesting the tablet this chemical substance will release nitric oxide into its new environment; well known for its properties of relaxation of the muscular walls and dilation of the blood vessels in particular in the cavernous body of the male’s penis. Thus a generous influx of blood will be directed to the reproductive organ in order to allow an optimization of its erection.

It should be noted that unlike aphrodisiacs Viagra does not guarantee an immediate erection. Its use must be accompanied by sufficient sexual stimulation of the penis if one wants to enjoy the effects.

It should be noted that these are available in several concentrations depending on the severity of the disorder faced by the patient.

The latter can be adjusted by the doctor according to its effectiveness on the patient and the intensity of the side effects.

Also it should be noted that to maximize the effects of this tablet use on an empty stomach is to be prioritized.
