Probably one of the nightmares that can dream of a modern man - a situation in which he was unable to realize himself as a skillful lover. And such a dream could not pursue a "macho" if not "but" - the emergence of the pharmaceutical market of drugs that can help restore sexual function.
The problem of erectile dysfunction affects men of almost all ages. As the polls have even the 25-year-old members of a strong half of humanity are confusion with using SMS with a partner. Reasons for this state are numerous: from psychological problems at work or at home to serious chronic diseases, which disrupted the normal flow (eg, cardiovascular disease, diabetes). But no man does not want to "go to the race" ahead of time. Therefore, many of them resorting to synthetic drugs, able to "stay young" in bed - Viagra, Levitra, Cialis and their generics.
In 1993 specialists of pharmaceutical company Pfizer synthesized a special substance sildenafil, which was to help patients with abnormalities of blood vessels. In the original version it had a vasodilator effect, and was tested on volunteers with coronary heart disease and hypertension.
What was the astonishment of pharmacists when they learned about the wonderful "side effects" of drugs - the ability to cause enhanced blood flow to the penis. This fact served as a determining factor in that, being patented under the trade name "Viagra" and goes on sale in 1998, the drug began to be used solely to increase potency.
According to all international legal norms, the original medication after patenting monopoly may be sold for over 5 years (occasionally allowed 10-year period). During this time the monopolist producer must through mass advertising campaign to make large volumes of medicament and a way to compensate for the billions spent on his invention and research. After 5 years of any other pharmaceutical company obtains the legal right to issue a similar drug with the same main active ingredient (in this case - sildenafil), but under another name. That is, the right to use the name "Viagra" belongs exclusively to Pfizer, which, for the invention of the drug has even received the Nobel Prize. But analogues (Generic) Sildenafil may have different names. Today, the most famous of them - Eregra, Silagra, Dzhenagra, capacity, Kamagra, Kaverta. At the heart of them all is the substance sildenafil.
Since all generic drugs before they go on public sale held a number of studies and obtain all necessary certificates, you are just as effective as counterparts. And here are much cheaper. For example, the success of generic "Viagra" depends on what they do not increase sexual desire (similar substances with pheromones), but act solely as an assistant to an erection, causing an increase in blood flow to the genitals. The use of generic "Viagra" is absolutely safe for older men who suffer from chronic diseases of the cardiovascular system or diabetes. They can be used for a long time without compromising their own health because they are not addictive. Moreover, there are cases when the background of continuous use of generic "Viagra" could fully restore natural erectile function. It is true that taking these drugs, like any other, it is necessary to carry out still under medical supervision.
Generic "Viagra" have virtually no side effects, such as possible discomfort, headache, indigestion, nasal congestion, pass without trace after a few medications.
Patients who decide to take Viagra or generic, should consider the following facts:
* Drinking grapefruit juice promotes the accumulation of substances in the body, so can an overdose of the drug;
* Reception of alcoholic beverages may increase the side effects;
* Use of the drug on an empty stomach leads to its rapid action.
