Erectile Dysfunction: Methods of Treatment
All individuals want to live successful sexual life and the age doesn't seem to be important. But, erection difficulties still bring about nervousness for a few males, make them restless and lower their self-rating. And it is obvious that everyone wants to be at his best in sex. In the most important cases impotence can lead to the comedown and even rupture of relationships.
Viagra (Sildenafil), Cialis (Tadalafil) and Levitra (Vardenafil) are three medicines for impotence which are almost the same from the point of view of pharmaceutics. At the same time, producers of each drug strive to prove that it's better than others, for the purpose of promotion. The luck of promotional campaigns rather than health indicators are probable to decide the fate of every drug and decide the most widespread of them. To buy Viagra online you are welcome to search on the Internet. There you can as well buy Cialis online.
All these drugs are the products of the series of medicaments named phosphodiesterase type 5 inhibitors. Erection is commonly enfeebled by PDE-5, the ferment that holds back the expansion of veins of the penis. The composition of Cialis is a little different from Viagra and Levitra, the organization and qualities of which bear much resemblance.
But actually the chief diversity between the drugs is that one of them (Levitra) is rapidly taken in, and another - Cialis - is heavily got out of the body. That's all FDE-5 blockers differ in time and duration of action but the influence they produce is actually similar.
In about 80 percent of cases all three drugs strike the target.
But Levitra produces an influence in rather low doses - 5-10 times smaller than those of the competitors. The drug is still contraindicated with disorders of cardiovascular system and after the apoplexy, although the strength of side-effects may be somewhat reduced.
One more after-effect is that all three medicaments obstruct all the other ferments including the “needed” FDE-5. For example, the FDE-6 enzyme, answerable for color sense, is affected by Viagra and Levitra. Cialis retrains the action of FDE-11 in the heart, thymus, or cerebrum. But what precise inappropriate outcomes it may cause has not yet been determined.
The interaction of these drugs with food and alcohol drinks is also of much importance. It's clear that taken on an empty belly Viagra has a much faster impact than with a meal. But one way or another the effect still occurs although slowly. The promotional booklets of Cialis guarantee that it does not interplay with alcohol drinks, as opposed to the rivals. In fact, there is info about Levitra being also safe in combination with alcohol drinks. But marketers are in no haste to use this “trump” and persuade all to buy Levitra. Because one of the frequent reasons of impotence is drink misuse this “trump card” appears to be equivocal.
