Erectile Dysfunction: How to Cure?
All people wish to live happy sex life and the age doesn't seem to be important. Nevertheless, erection troubles still produce uneasiness for some males, make them restless and lower their self-appraisal. And undoubtedly anybody wants to at his best in sexual affairs. In the most significant situations impotence can lead to the comedown and even break of relations.
There are 3 most general drug preparations for erectile dysfunction: Viagra (Sildenafil), Cialis (Tadalafil) and Levitra (Vardenafil). From the point of view of pharmaceutists, they're almost identical. At the same time, producers of each medicine try to prove that it's better than others, for the sake of promotion. And it's the fortune of ad campaigns rather than health parameters that would decide which of these drugs would be the most prevailing. To buy Viagra online please search on the Internet. To buy Cialis online contact the same web-shops.
The series of phosphodiesterase type 5 inhibitors includes all three drug preparations. Erection is generally enervated by PDE-5, the ferment that suppresses the expansion of vessels of the phallus. The organization and characteristics of Viagra and Levitra are quite similar. The structure of Cialis is a little different.
But Levitra is fast taken in and Cialis is lingeringly driven out of the body, and that is the main difference between the medicines in fact. That is all FDE-5 blockers have nearly identical influence. They vary in term and duration of act.
In about 80 percent of situations all 3 drugs hit the mark.
But Levitra is effectual in quite low dosage. The dose is 5-10 times smaller than those of the opponents. The density of side-effects can be a little decreased because of this. But the medicament is still contraindicative with disorders of cardiovascular system and after the apoplexy.
There is something more on after-effects: all 3 drugs obstruct not only the “needed” FDE-5 enzyme but as well the others. E.g., the FDE-6 enzyme, responsible for color sense, is influenced by Viagra and Levitra. Cialis retrains the activity of FDE-11 in the heart, thymus, or brain. But what precise unsuitable effects it may produce is still not obvious.
Another essential question is the interplay of these drugs with food and alcohol drinks. It's well known that it's better to take Viagra on an empty belly so as to get better and prompt impact than with a meal. Nevertheless, the effect still happens but later. As regards alcohol drinks, Cialis as affirmed in the advertising brochures doesn't interplay with it - in contrast to the rivals. As a matter of fact, in conjunction with alcohol drinks Levitra is also harmless. But this “trump card” hasn't yet been used brought by the marketers to persuade all to buy Levitra. Probably because the “trump” is doubtful: alcohol abuse is one of the frequent reasons of impotence.
