The mechanism of action of Viagra on men

Generic Viagra is a drug that allows you to restore an erection. This problem occurs in many men and worsens with age, while the causes can be both physical ailments and psycho-emotional state of a person. Dysfunction is a congenital pathology or acquired, but its manifestation is always the same – the man is completely or partially absent erection.

Age-related changes in the body of a man, injuries, bad habits, hereditary predisposition and other negative factors may not be the best way to affect the state of male health. The result of pathological changes is usually erectile dysfunction, which leads to the stronger sex to experiences that gradually turn into neuroses. If therapy with conventional drugs does not give the desired effect, an excellent alternative to standard means become more powerful and narrowly focused means, which include Viagra.

Impotence can be caused by:

Constant stress and neurotic disorders. Depression. Pathological dependencies (alcoholism, drug addiction). Heart disease. Lesions of the spinal cord and brain (back injury or skull, the development of infections). Diseases of blood vessels and genitourinary system (prostate adenoma, prostatitis, etc.)). Since Viagra does not treat the cause of impotence, the urologist is likely to prescribe complex medical therapy. In 90% of cases, such a violation is completely curable with proper approach and a healthy lifestyle. Sometimes impotence is associated with psychological factors, for example, a man can not have sex, if the partner is not blonde and so on. In this case, a visit to a psychologist will be recommended. The disorder can develop in men of any age, recorded cases of impotence and 18-20 years. But in the main risk group are men after 40 years, who lead an unhealthy lifestyle, consume large quantities of alcohol, smoke and practice irregular sex life.

What is the effect of viagra on men?

To answer this question, you should understand why the erection disappears. The fact that the body has an enzyme called phosphodiesterase, it is able to affect the blood flow in the cavernous bodies of the penis. Under the influence of certain factors (stress, urological infections, etc.).) the enzyme affects blood circulation. In fact, he stops her in the cavernous bodies, thereby completely stopping the erection. When swallowing viagra tablets, the main active ingredient sildenafil, which is an inhibitor of this enzyme, quickly absorbed into the thin walls of the intestine, and after 15-20 minutes after taking already circulates through the blood vessels. Sildenafil blocks phosphodiesterase, relaxes smooth muscles, thereby restoring and increasing blood flow in the penis. After 30-60 minutes, the maximum concentration of the drug in the blood is observed, if it was drunk on an empty stomach. In this case, the drug does not treat the true cause of dysfunction, but successfully eliminates its manifestations.
