Curing of Impotence
It is all the same how old they are, people are concerned about their sexual happiness and consider it to be important. However, some males have great difficulties with their erection. It worries them much and lowers their self-esteem. And it's clear that any man wishes to be at his best in sexual affairs. In the most important situations erectile dysfunction can lead to the letdown and even break of relationships.
Three drug preparations treating impotence - Viagra (Sildenafil), Cialis (Tadalafil) and Levitra (Vardenafil) - are nearly similar as far as pharmaceutics is concerned. Meantime, manufacturers of every medicament strive to prove that it's better than others, with the view of promotion. The most widespread of these drugs is likely to be decided by the fortune of ad campaigns rather than medical parameters. To buy Viagra online you are welcome to search on the web. One may also buy Cialis online there.
All these medicines are the representatives of the group of medicines called phosphodiesterase type 5 inhibitors. The enzyme that suppresses the expanse of vessels of the phallus is PDE-5. So it enervates erection. The composition and qualities of Viagra and Levitra are very identical. The structure of Cialis is somewhat divergent.
But practically the main difference between the drugs is that 1 of them (Levitra) is quickly absorbed, and another - Cialis - is slowly driven out of the body. That's all FDE-5 inhibitors disagree in time and duration of activity but the influence they produce is practically the same.
All three medicines are effective in approximately 80 percent of situations.
But Levitra is resulting in quite small dosage. The dosage is 5-10 times lower than those of the competitors. The drug preparation is still contraindicative with disorders of cardiovascular system and after the apoplexy, though the density of ill-effects may be slightly diminished.
There's still more on under-effects: all three drugs obstruct not only the “needed” FDE-5 ferment but as well the others. E.g., Viagra and Levitra have an affect on the FDE-6 ferment, which is responsible for chromatic sensitivity. The cerebrum, heart, or thymus gland are controlled by FDE-11, the action of which can be suppressed by Cialis. But no one has yet found out what exact undesirable effects it may cause.
The interaction of these drug preparations with nourishment and alcohol is also of much importance. It's evident that it is better to take Viagra on an empty stomach in order to receive better and prompt impact than with food. But in any case the effect still befalls although slowly. Regarding alcohol drinks, Cialis as formulated in the promotional brochures doesn't interplay with it - unlike the rivals. In point of fact, there is info that Levitra is also innocuous in conjunction with alcohol, only this “trump card” hasn't yet been brought by the marketers persuading all to buy Levitra. It's obvious that the “trump card” is questionable: one of the widespread causes of erectile dysfunction is drink overindulgence.
