The medical center located in Cologne conducted a series of studies, as a result of which it turned out that the effectiveness of Levitra is several times greater than the effect of other drugs that improve potency. Despite the fact that the active substance (vardenafil) is short-lived, about 3-5 hours, this time is more than enough for a man to have high-quality sexual intercourse.
To understand how the medicinal substance works, let's look at what erection is. This process is hemodynamic. The drug gives access for the blood to the cavernous bodies of the penis, and as a result of stimulation, nitric oxide is released. This chemical activates the enzyme that synthesizes cGMP. Vardenafil stops this process, so the release of nitric oxide does not happen, which causes an increased sensitivity of the intimate areas in men. It is worth remembering that Levitra has the best effect immediately before sexual contact. Thus, after the process of ejaculation, the effect of the drug fades away, but with repeated stimulation, an erection will appear again.
If a man experiences excitement, then the drug will work. Based on the results of research, Levitra can be used by people with severe diabetes mellitus and those who have undergone removal of the prostate gland.
