Impotence Therapy

Sex happiness is important for all individuals, irrespective of the age. Nevertheless, there are some men with erection troubles that cause anxiety resulting in lower self-rating. And certainly anyone needs to up to the mark in sex. Frequently it is erectile dysfunction that leads to the letdown and even break of relationships.

Viagra (Sildenafil), Cialis (Tadalafil) and Levitra (Vardenafil) are three medicines for impotence which are nearly the same from the point of view of pharmaceutics. At the same moment, with the view of advertising manufacturers of each drug preparation urge that it is better than others. The luck of promotional drives rather than health parameters are likely to determine the destiny of every medicine and decide the most widespread of them. Various web-stores would assist one buy Viagra online. You can as well buy Cialis online there.

The group of phosphodiesterase type 5 inhibitors comprises all 3 drugs. The enzyme that holds back the expanse of vessels of the penis is PDE-5. So it enervates erection. The structure and characteristics of Viagra and Levitra are quite similar. The structure of Cialis is something different.

But Levitra is rapidly absorbed and Cialis is lingeringly got out of the body, and that's the principle difference between the drug preparations in practice. That is the impact of all FDE-5 inhibitors is actually identical but divergent in time and continuance of activity.

All three medicines are efficient in about 80 percent of situations.

But Levitra produces an influence in rather low dosage - 5-10 times smaller than those of the rivals. This slightly reduces the density of after-effects, but with disorders of cardiovascular system and after the apoplexy medicine is as before contraindicative.

There is something more on side-effects: all 3 drug preparations obstruct not only the “required” FDE-5 ferment but as well the others. For example, Viagra and Levitra produce an influence on the FDE-6 enzyme, which is responsible for chromatic sensitivity. The cerebrum, heart, or thymus gland are controlled by FDE-11, the action of which may be suppressed by Cialis. But nobody has yet clarified what exact inappropriate effects it can produce.

One more aspect is the interaction of these medicines with alcohol drinks and food. It's well known that taken on an empty belly Viagra has a much faster impact than with food. But at all events the effect still occurs although slowly. Regarding alcohol, Cialis as affirmed in the advertising prospectuses doesn't interact with it - unlike the rivals. As a matter of fact, there's information about Levitra being also harmless coupled with alcohol. But marketeers are in no haste to bring this “trump card” and convince all to buy Levitra. Because 1 of the widespread reasons of impotence is alcohol abuse this “trump” seems to be questionable.
