How Viagra works Viagra is one of the most common pharmaceutical products used to improve male potency. There are many reasons for its use, from erectile dysfunction to impotence and pulmonary hypertension. And even those men who have never had an erection problem sometimes want to find out how Viagra 100mg works and what the effect of its use is. Today, the name of this drug is already considered to be a nominal one, because it is this drug that started the production of countless drugs that successfully combat sexual powerlessness and help the stronger sex to diversify their sexual life. What is Viagra   If there are only a few people who know about the action of the drug, then almost everyone has information about what Viagra gives. Any man can say with certainty that the drug is used to improve erection and has a beneficial effect on male potency. And it is indeed so. Viagra is based on the active substance sildenafil, which is part of the group of selective inhibitors FDE-5 and effectively affects the smooth musculature of the cavernous body in the penis.   The original preparation is available in double convex blue tablets with dosages of 25, 50 and 100 mg. Its main purpose is to solve problems with erectile dysfunction of various etiologies, including those related to psychogenic and physiological factors. As statistics show, a high effect in the fight against erectile dysfunction when taking Viagra is observed in 80% of cases. Approximately 15% of patients say that the drug does not help much with impotence, and only 5% of men who tried the drug, noted a complete lack of results.    Why is Viagra powerless? You should take into account the fact that sildenafil acts only when there is sexual arousal. The substance affects the natural processes of erection, so if a man is not ready for sexual intercourse and does not feel sexual desire for a woman, the drug will not work. In addition, Viagra does not always help members of the stronger sex, who have low levels of testosterone or found violations of the inner shells of blood vessels. A good alternative for Viagra are: Cialis 20mg, Levitra 20mg, Kamagra oral jelly. How did Viagra appear?   The history of the creation of Viagra is a vivid example of drug repositioning.    Sildenafil was synthesized by a group of pharmaceutical chemists working at Pfizer's research center in Sanuijah, Kent County, England. Originally, it was designed to treat hypertension and angina, but in the first phase of clinical trials, scientists found that the drug has little effect on ischemia, but can cause a noticeable penis erection. As a result, the owners of Pfizer decided to introduce it to the market not as a tool to combat angina, but as a panacea for sexual impotence.    Viagra was patented in 1996 and approved for use on March 27, 1998. Since its introduction, it has been a huge success around the world, with annual sales reaching a peak in 2008 of 1.934 billion dollars. As time passed, Viagra began to have analogues, including those of natural origin, but today it still remains the most popular remedy for lack of erection and allows men to get maximum pleasure from intimacy. How Viagra works: the effect of taking the drug To understand the principle of the drug, you should first find out how an erection occurs. Its beginning is sexual arousal, through which there is an expansion of blood vessels in the small pelvis and there is a rush of blood to the penis. Under the influence of increased blood flow, the penis becomes larger in size, gets harder and ready for sexual intercourse.    Due to certain negative factors (stress, disease, prolonged treatment with antihypertensive agents, etc.) there may be a violation of blood circulation in the body with the lack of necessary blood flow in the small pelvis. This phenomenon is often the cause of inadequate erection or its complete absence, which leads to sexual impotence. If the problems in bed are observed repeatedly over a long period of time, the man is diagnosed with "erectile dysfunction".    Today, there are many drugs aimed at improving potency, but none of them is as effective as Viagra. The fact is that the drug has a strictly directed action and eliminates the direct cause of erectile dysfunction, namely a blood circulation disorder in the penis. Sildenafil relaxes the smooth muscles of the cavernous body and makes blood flow in the penis more intense. In addition to improving potency, the drug has the following features: enhances the quality of sexual intercourse prolongs coition increases the sensual perception and makes the orgasm more vivid shortens the recovery period between intercourse   Viagra affects the natural ability of the penis to soy, that is, it does not give men anything that they are not able to do on their own. However, for the stronger sex, suffering from sexual powerlessness, the drug gives something that they could not even dream of before - quality sex without discomfort and embarrassment to the partner.
