Viagra

Viagra is the brand name of a very popular and well-known drug in the treatment of erectile dysfunction (also incorrectly called impotence). Its active ingredient, Sildenafil, determines the relaxation of the smooth muscles of the corpora cavernosa of the penis, guaranteeing a more consistent and lasting erection. Viagra is therefore useful in all those cases in which there is a proven inability to achieve or maintain a "erection suitable to allow" satisfactory sexual activity.

Viagra comes in the form of blue, diamond-shaped tablets with rounded tips, which may contain the active ingredient in varying dosages (25, 50 or 100 mg). For the drug to work, the "individual" must be sexually stimulated; in the absence of arousal, viagra, at the recommended dosages, is therefore devoid of action. For the same reason it cannot be considered an aphrodisiac, since, fundamentally, it does not increase sexual desire, but merely enhances the physiological mechanism of " erection if this has already been triggered by an erotic stimulus.

The famous blue pills should be taken when needed, at dosages between 25 and 100 mg, one "hour before" sexual activity; the desired effect appears within 30-60 minutes of taking and remains active for about four hours. When taken in conjunction with a meal, viagra can exert its stimulating effect with a certain delay. In any case, it is recommended not to exceed the recommended intake doses; the product should not be administered more than once a day.

An "intake exceeding the recommended limits leads to prolonged erections or cases of priapism (painful erections lasting more than 4-6 hours), with the risk of permanent damage to the erectile tissues and consequent irreparable loss of sexual abilities. For this reason, if this occurs. just in case, it is good to leave all kinds of taboos at home and run to a doctor.

In Italy, viagra, in class C, is sold on presentation of a non-repeatable medical prescription. This is to preserve the health of patients, since the drug can be very dangerous for certain categories of subjects. In no case should it be considered a recreational drug, should not be taken together with alcohol or drugs and in the absence of a real and well documented erectile dysfunction problem.

For no reason should viagra be purchased on the internet or through channels other than the pharmacy; first of all there is no guarantee on the real concentration of the active ingredient but, above all, there is no certainty about the safety of the product and, very often, about one's physical fitness. to the treatment.
