The action of Viagra, Levitra and Cialis on the male body

Viagra, Levitra and Cialis belong to inhibitors of the enzyme PDE-5. This enzyme is produced in the body of every man and participates in the process of relaxing the walls of the vessels of the penis.

Potency occurs under the influence of increased blood flow, which flows to the head of the penis of a man. During sexual stimulation, nitric oxide is produced in the cavernous tissue of the genital organ. The substance activates the production of guanylate cyclase. As a result of the reaction in the vessels of the penis, an enzyme cGMP is produced. With cGMP concentration, the walls of the vessels relax, and the blood flow to the penis increases. If the level of cGMP in the body is not enough, the vessels remain unchanged and the erection does not occur.

Enzymes PDE in the body split cGMP. In the vascular system of each part of the body, their enzymes are produced:

  • PDE 5 – in the penis;
  • PDE 6 – in the retina of the eye;
  • PDE 4 – in the human lungs.

In the sexual organ, PDE 5 actively cleaves cGMP and the relaxation of the walls of the vessels does not occur. Inhibitors slow the work of PDE 5 and the concentration of cGMP in the blood increases.

Difference in the effects of drugs

The drugs equally affect the body, the difference only in the time of onset of therapeutic effect and in the effect on PDE in other parts of the human body.

Let’s consider in more detail the therapeutic effect of drugs in the form of a table:

Cialis is a selective inhibitor and during the action stops only PDE-5. Therefore, the drug does not affect the heart and retina of the eyes. During the reception of Viagra, 15% of men change their color perception. The inhibitor has a slight effect on PDE-6 and the male receptivity to blue and green colors is lost. Loss of color perception is temporary and after withdrawal from the body completely passes. Levitra also affects the eyesight in men, but insignificantly. In 5% of patients after receiving a decrease in the perception of blue.

If a man wants to get a quick erection, then it’s worth stopping the choice on Cialis or Levitra. Viagra refers to the drugs of the first generation, and it begins to act in 40-50 minutes. But it costs a tablet cheaper and will help save the family budget.
