The word Viagra now has become a household name. At the same time, not everyone knows what the preparation is intended for and how to use it correctly.
As you understand, we are talking about drugs that increase the potency or, in the language of doctors, used to treat erectile dysfunction, or impotence. This problem is very urgent, because on average about 30% of men aged 30-35 years already have problems with erection, can not live a normal sex life. At the age of 40-50 this percentage increases.
The drug Viagra appeared recently, about 15 years ago. The German firm conducted a study of a medicine for the treatment of cardiovascular diseases, 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, Viagra has saved many families, has given pleasure to many women and men.
The more interesting thing in this drug is the fact that when there is sexual arousal, then there is an erection. That is, Viagra is designed to increase blood supply in the penis to achieve and support an erection.
If a man took the pill, and his sexual organ did not accept combat readiness, then there is no sexual arousal. Excitation arises from direct contact with a woman of interest: caresses, embraces, kisses, inhalation of pheromones, etc. Then under the influence of Viagra there is an erection, which the same drug maintains and retains throughout the sexual intercourse. After the end of the sexual act, the excitement subsides, and the drug again ceases to function.
Since sexual arousal depends on the level of testosterone, the drug for people with low levels of male sex hormone is less effective. The drug acts weakly on men with certain diseases, for example, with diseases of the inner shell of the vessels (endothelium). If the endothelium produces a little substance, which is the mediator of an erection, then Viagra also acts poorly. This is observed in patients with diabetes mellitus, in patients with metabolic syndrome.
After the invention of Viagra, other drugs appeared, similar in effect. Next was Levitra. It has fewer side effects, it affects the vessels of the penis more and less on others (from Viagra there are headaches due to concomitant expansion of the vessels of the head, there is a swelling of the nose due to the expansion of the vessels of the mucosa).
The third drug is Cialis. This drug was invented by Americans, and it has a fundamentally different formula. Cialis is active for 36 hours due to the fact that it has a longer half-life in the body. If you use it 2 times a week, then you can live a normal sexual life all week. This does not mean that all 36 hours there is an erection. As it was said above, it arises only when there is sexual arousal. All these products without a prescription are sold here apothekegenerika.de/pille-online-bestellen-ohne-rezept/
