How does the ingredient in Viagra work?
Sildenafil is the active ingredient in Viagra and is used to treat impotence (erectile dysfunction).
The causes of impotence can be many reasons. In men aged 50 and over, it is usually other diseases such as arteriosclerosis or high blood pressure. Then the impotence is an important early warning sign for these diseases. You can definitely be treated with Viagra. In about 20 percent of cases, the impotence is psychological, especially in the age group up to 35 years.
The erection of the penis is based on a rapid influx of blood into the erectile tissue. For this purpose, the arteries must expand. This is only possible if the surrounding muscles relax.
During sexual stimulation with Viagra, the messenger substance nitrogen monoxide (NO) is released. He is activating a second messenger, the cGMP. Only the cGMP allows the muscle cells in the erectile tissue to relax and thus enables blood to flow in and an erection. To stop the erection, cGMP is broken down again by the enzyme phosphodiesterase 5 (PDE-5).
Viagra Sildenafil is a PDE-5 inhibitor. It blocks the enzyme phosphodiesterase 5. This means that more cGMP remains in circulation, muscle relaxation is increased and the erection is improved.
Because of this mechanism, sildenafil only works in sexually aroused men. It has no lust-increasing effect and therefore cannot force an erection.
