Viagra is among the pioneering medications created to enhance male virility, even in challenging scenarios with confirmed erectile dysfunction. It contains sildenafil, a compound renowned for its ability to rejuvenate a man's sexual activity. The medication transforms a dull sexual life into a realm of positive emotions experienced not only by the man himself but also by his sexual partner.
Viagra dilates blood vessels in the body. The drug has an effect on the smooth muscle tissue of the cavernous body, due to which it relaxes. More blood enters the vessels passing through the male genital tract. Accordingly, there comes a fast erection. In fact, Viagra is a means to improve blood circulation and dilate blood vessels in the body. But it is used exclusively for problems with erection.

About the indication
Among the indications for taking Viagra are:
- erectile dysfunction;
- inability to complete sexual intercourse;
- impotence;
- complete absence or significant decrease in libido.
It is worth paying attention to the fact that the studied drug is not a medicine. It does not solve the issue of erectile dysfunction. But for a while, you can forget about problems with potency and erection with the help of Viagra.
Viagra's efficacy stems from sildenafil's ability to activate specific compounds that engage with nitrogen oxide present in the penile muscles, thereby stimulating the dilation of the blood vessels within this organ.
Consequently, the penis becomes engorged with a substantial amount of blood, leading to an erection. The effects of the medication persist for around five hours, during which time the metabolites are expelled from the tissues.
