Why and How Take Viagra?

A bit of history. The drug Viagra appeared recently, about 15 years ago. German company conducted a study of a drug for the treatment of cardiovascular disease, invented by one of the German pharmaceutical companies. One of the side effects of the drug was the appearance of an erection in the presence of sexual arousal. In the course of further development, Viagra appeared. Since then, the drug Viagra has saved many families, has pleased many women and men. What is Viagra affected by? What is interesting about the drug - when there is sexual arousal, an erection occurs. That is, Viagra pill is designed to increase blood supply to the penis to achieve and maintain an erection. If a man took the drug, and his sexual organ did not accept combat readiness, then he did not have sexual arousal. Excitation arises in direct contact with a woman of interest to a man: affection, hugs, kisses, inhalation of pheromones, etc. Then, under the influence of Viagra, an erection appears, which the same drug supports and holds throughout the entire sexual intercourse. After sexual intercourse, the excitement subsides, and the drug again ceases to act. Who will not help Viagra. Since sexual arousal depends on the level of testosterone, the drug is less effective for people with low levels of male sex hormone. The drug acts weakly on men with certain diseases, for example, with diseases of the inner lining of the vessels (endothelium). If the endothelium produces little substance, which is a mediator of erection, then Viagra for men also has a bad effect. This is observed in patients with diabetes mellitus, in patients with metabolic syndrome. The drug is contraindicated in women. Viagra is ineffective for people with severe atherosclerosis. With this disease, the vessels can not expand, but an erection is an expansion of the arteries of the penis. What are the viagra side effects? Sometimes in the media you can find news that someone died from Viagra. In fact, the person suffered not from Viagra, but from the load that he gave his body during coition. After all, sexual intercourse is a kind of stress for the body, while the load on the cardiovascular, respiratory, muscle system, central nervous system is carried out. If a person for health reasons cannot bear these loads, then Viagra has nothing to do with it. Medical contraindications include allergic reactions to the composition of the drug, intolerance to individual components, as well as diseases in which it is contraindicated to live sexually. What else besides Viagra? Viagra and Cialis. After the invention of Viagra, other drugs similar in effect appeared. The next one was Levitra. It has fewer side effects, more affects the vessels of the penis and less on others (from Viagra there are headaches due to the concomitant expansion of the vessels of the head, there is a swelling of the nose due to the expansion of the vessels of the mucous membrane). The third drug is Cialis (Tadalafil Esculap). This drug has already been invented by the Americans, and it has a fundamentally different formula. Cialis acts for 36 hours due to the fact that it has a longer half-life in the body. If it is used 2 times a week, then you can live a normal sex life all week. This does not mean that all 36 hours there is an erection. As mentioned above, it occurs only when there is sexual arousal.You can buy Viagra online in a store that has over 10 years of experience. No matter how popular methods of treating impotence are advertised, not one weed can reach the level of Viagra.
