Sex happiness is essential for all men and women, regardless of the age. However, there are some males with erection problems that bring about anxiety giving rise in lower self-esteem. But undoubtedly anyone needs to at his best in sex. Comedown and even rupture of relationships may very often be a consequence of erectile dysfunction.

3 medicaments treating erectile dysfunction - Viagra (Sildenafil), Cialis (Tadalafil) and Levitra (Vardenafil) - are nearly identical as far as pharmaceutics is concerned. At the same time, manufacturers of each drug strive to prove that it is better than others, by way of advertising. The most prevailing of these medicines is probable to be determined by the fortune of promotional campaigns rather than medical indicators. There's no difficulty to buy Viagra online in different web-shops. To buy Cialis online contact the same web-shops.

All these drugs are the elements of the series of drug preparations named phosphodiesterase type 5 inhibitors. The enzyme that retrains the stretching of veins of the phallus is PDE-5. So it enfeebles erection. The composition and properties of Viagra and Levitra are rather identical. The organization of Cialis is something different.

But actually the main difference between the drugs is that 1 of them (Levitra) is fast taken in, and another - Cialis - is heavily got out of the body. That is all FDE-5 inhibitors disagree in term and endurance of act but the effect they produce is essentially identical.

In approximately 80 percent of cases all 3 drugs hit the mark.

But Levitra produces an influence in rather small doses - 5-10 times smaller than those of the rivals. This slightly diminishes the intensity of side-effects, but with diseases of cardiovascular system and after the cerebrovascular accident medicament is still contraindicative.

There is something more on after-effects: all 3 medicines block not only the “needed” FDE-5 enzyme but as well the others. For example, Viagra and Levitra produce an impact on the FDE-6 enzyme, which is responsible for color sense. The cerebrum, heart, or thymus gland are regulated by FDE-11, the activity of which can be retrained by Cialis. But what exact undesirable effects it may cause is still not obvious.

Another important question is the interplay of these drug preparations with food and alcohol. It's known that it's better to take Viagra on an empty stomach so as to get better and fast impact than with a meal. But at all events the effect still befalls although lingeringly. As regards alcohol drinks, Cialis as affirmed in the promotional booklets doesn't interplay with it - as opposed to the competitors. As a matter of fact, there's info that Levitra is also innocuous in combination with alcohol drinks, only this “trump card” hasn't yet been brought by the marketers convincing all to buy Levitra. Perhaps because the “trump card” is questionable: alcohol misuse is 1 of the widespread reasons of impotence.
