No matter how old they are, men and women are concerned about their sexual life and consider it to be significant. But, some men have great troubles with their erection. It worries them much and diminishes their self-esteem. And certainly everybody wants to at his best in sex. Aggravation and even break of relationships can very often be a consequence of erectile dysfunction.

There are 3 most common medicines for impotence: Viagra (Sildenafil), Cialis (Tadalafil) and Levitra (Vardenafil). From the point of view of pharmaceutists, they're nearly identical. Meanwhile producers of each medicine strive to persuade the audience that it's better than others. The most popular of these drugs is probable to be determined by the success of ad campaigns rather than health indicators. Different web-stores would help you . One can also there.

The group of phosphodiesterase type 5 inhibitors comprises all three drugs. PDE-5 is the ferment which holds back the expansion of vessels of the penis, and thereby - enfeebles erection. The organization of Cialis is something different from Viagra and Levitra, the organization and characteristics of which have much in common.

But Levitra is fast absorbed and Cialis is slowly got out of the organism, and that is the principle difference between the drugs in practice. That is the impact of all FDE-5 blockers is essentially the same but different in term and duration of act.

All three drug preparations are efficient in approximately 80 percent of situations.

But Levitra produces an impact in rather low dosage - 5-10 times lower than those of the rivals. The medicine is as before contraindicated with diseases of cardiovascular system and after the cerebrovascular accident, though the intensity of after-effects can be slightly decreased.

And still more data on ill-effects: all 3 drugs, besides the “required” FDE-5 ferment, also block the others. E.g., the FDE-6 enzyme, responsible for chromatic sensitivity, is influenced by Viagra and Levitra. The cerebrum, heart, or thymus are controlled by FDE-11, the activity of which can be retrained by Cialis. But what exact inappropriate results it may bring about is still not distinct.

One more significant point is the interplay of these drug preparations with nourishment and alcohol. It's well known that taken on an empty belly Viagra produces a much quicker impact than with food. However, the impact still happens but later. Concerning alcohol, Cialis as formulated in the advertising prospectuses does not interact with it - in contrast to the rivals. As a matter of fact, there's info that Levitra is also harmless in conjunction with alcohol drinks, only this “trump” hasn't yet been brought by the marketeers urging all to . It's evident that the “trump card” is questionable: one of the widespread causes of impotence is drink overindulgence.
