Studies at the Cologne Medical Center showed that Vardenafil, the active ingredient in Levitra, is the most powerful PDE5 inhibitor in the treatment of impotence.
The effect period of the active substance is 3-5 hours, which is quite enough for a sexual intercourse.
The benefits of the drug include:
The effect of the drug consists in response to sexual stimulation, Vardenafil begins to block the enzyme PDE5, which leads to the release of nitric oxide and the accumulation of cGMP in the cavernous bodies. As a result, the blood flow to the penis increases and a natural erection occurs.
The drug begins to act at the moment of sexual arousal, and after ejaculation, its action is suspended until the next sexual stimulation.
Clinical trials have shown that Levitra intake by men suffering from diabetes, as well as those who have undergone surgery to remove the prostate gland, gives a positive effect in most cases.
