Pharmacological action of pills for potency

Many men come to urologists every day to solve the problem of weak erection or its complete absence. After taking Viagra, Cialis or Levitra pills prescribed by a doctor, patients enjoy an established sex life and do not think about the principle of their action on the body.

Cialis, Levitra and Viagra have different active substances in the composition, but the principle of their action on the man's body is the same. How erection occurs normally without synthetic stimulants:

1. Under the influence of sexual stimulation, nitric oxide produced by the body enters the penile tissue.
2. It creates cyclic guanosine monophosphate, which relaxes the smooth muscles of the penis.
3. Due to this, the blood actively fills the cavernous body and a natural erection occurs.
4. After the cyclic guanosine monophosphate enters the blood, the body produces the enzyme phosphodiesterase 5-type, which gradually reduces its level, and the erection disappears.

To prevent such a cycle from ending too quickly, Levitra, Cialis and Viagra tablets strongly inhibit the production of the enzyme phosphodiesterase 5-type. Then the fullness of the cavernous body with blood remains high even after 30 minutes of sex. Due to this very principle of action, Cialis, Viagra and Levitra are not addictive, since they do not deliver additional nitric oxide to the body. This could also make an erection qualitative, but in this case, nitric oxide would cease to be produced naturally, and a man could have sex only under the influence of Viagra tablets, Levitra or Cialis.

But no matter how Cialis, Levitra or other drugs for potency seem safe, they should be taken only after consulting a doctor.
