Action Viagra and Sialis is a placebo effect?

Before the discovery of Viagra in men with erectile dysfunction, the impression was created that all their sexual problems in the head. Partially it is true even in our age of small blue tablets, approves Jama Network Open edition.

In a significant number of men who received placebo in clinical tests of drugs from impotence, an improvement in their sexual function was observed, researchers in the report published on March 20 of this year.

The effect was the most pronounced in men with post-traumatic stress disorder, this suggests that for some of them, psychology is more important in the fight against erectile dysfunction. / P>

"The positive reaction to placebo is more significant when the cause of erectile dysfunction is mainly associated with psychogenic factors, as with post-traumatic stress disorder."

For the analysis, his team combined data 63 data with the participation of more than 12,500 men. The results showed that Viagra and its analogs have a strong effect, helping patients with erectile dysfunction caused by chronic diseases.

"The results included in this meta-analysis were mainly obtained during the examination of men with erectile dysfunction due to cardiovascular diseases, diabetes, etc., according to Street. "It is likely that there is a limit of how much the brain can affect the erection when the problem mainly lies in the dysfunction of blood vessels or peripheral nervous system."

Scientists have found that men in a placebo group also experienced a slight or moderate improvement in their erectile function.

"It is especially important to learn the root causes of erectile dysfunction in a man, it will help determine which treatment option will be the best," says Street. Some patients can get more benefit from psychotherapy, others from medication, he added.

"It is obvious that Viagra and other drugs for the treatment of erectile dysfunction work very well in many cases, but we should not ignore the importance of the psychological aspects of impotence, especially in men who have no obvious physiological reasons for such a state."

"Considering a significant decrease in the symptoms after receiving placebo among patients with post-traumatic stress disorder, it can be assumed that the doctors should work on eliminating the factors of psychological stress, before making the admission of pharmaceuticals for the treatment of erection," said Urologist Manish Vire from the Institute of Urology, New -York.

Studies have also shown that similar Viagra do not better work than placebo, for long-term restoration of the erectile function after the treatment of prostate cancer, which is common practice, which, he added, "seems to be doubtful."

Although the results seem to indicate that some men will be useful for therapy with the help of "pacifiers", Street warns that natural fluctuations in the severity of symptoms can be a tangible placebo effect. "Patients have a habit of treating assistance when their condition deteriorates and it can be improved during a couple of weeks, regardless of the appointed treatment," he said.
