It is all the same how old they are, men and women care about their sex life and think it to be essential. But, erection troubles still produce nervousness for some men, make them restless and lower their self-appraisal. And it is natural that anybody needs to be at his best in sex. In the most urgent situations impotence can bring to the aggravation and even rupture of relations.
There are three most common medicaments for erectile dysfunction: Viagra (Sildenafil), Cialis (Tadalafil) and Levitra (Vardenafil). From a perspective of pharmaceutics, they are almost similar. Meanwhile, manufacturers of every drug preparation try to prove that it's better than others, by way of promotion. The most prevailing of these drug preparations is likely to be decided by the luck of advertising campaigns rather than medical indicators. Different web-shops will assist one buy Viagra online. To buy Cialis online contact the same web-stores.
All three drug preparations belong to the group of phosphodiesterase type 5 inhibitors. The enzyme that retrains the stretching of vessels of the phallus is PDE-5. So it enervates erection. Viagra and Levitra are quite identical in organization and properties, and the structure of Cialis is something divergent.
All these drugs are in fact identical only Levitra is fast taken in and Cialis is heavily driven out of the body. That is the effect of all FDE-5 blockers is practically identical but diverse in term and continuance of action.
In about 80 percent of situations all 3 medicines strike the mark.
But Levitra has an impact in quite small doses - 5-10 times lower than those of the competitors. The drug is still contraindicative with diseases of cardiovascular system and after the apoplexy, though the strength of after-effects may be a little decreased.
1 more after-effect is that all three medicaments block all the other enzymes including the “needed” FDE-5. For instance, Viagra and Levitra have an impact on the FDE-6 enzyme, which is answerable for color sense. The brain, heart, or thymus gland are controlled by FDE-11, the action of which can be held back by Cialis. But nobody has yet clarified what precise unsuitable results it may bring about.
One more significant point is the interplay of these medicines with nourishment and alcohol. It is known that taken on an empty stomach Viagra has a much faster effect than with a meal. But one way or another the effect still occurs though lingeringly. Cialis does not interact with alcohol drinks as its promotional brochures run, as opposed to the competitors. In point of fact, in conjunction with alcohol Levitra is also harmless. But this “trump card” hasn't yet been used brought by the marketers to persuade all to buy Levitra. As 1 of the frequent reasons of impotence is alcohol abuse this “trump card” seems to be equivocal.
