Effects of Viagra

based on the relaxation of smooth muscles and increasing blood flow
to the cavernous body. Achieved this effect is due to inhibition of
the enzyme with a difficult name - phosphodiesterase type 5. Simply
put, the drug dilates the blood vessels of the penis during sexual
arousal. As a result of increased blood flow to the penis, which
contributes to a normal erection.
Like
many great discoveries, the effect of the drug was discovered by
chance in 1992 by the pharmaceutical company "Pfizer" The
clinical trial of a new drug on volunteers sildenafil for the
treatment of heart disease. However, the necessary influence on the
heart has been received, but drew attention to the "side effect"
of the drug in the form of increased potency in men, the latter did
not even want to leave it. Since 1998, Viagra was first introduced in
the U.S. Pharmacies.
statement
Viagra
- a drug used to treat erectile dysfunction. That's just what this
state really no one knows. The most frequent response specialists,
"is a pathological condition in which a decreased quality of
erections in men, and as a consequence - the impossibility of full
sexual intercourse."
Most often these disorders occur in men over 40 years. But often they occur in other age groups. Studies on the prevalence of erectile dysfunction, and many in Russia and abroad. The most accurate is "Program for the Study of aging men in Massachusetts." In a survey of 1709 men aged 40 to 70 years old with erection problems in one way or another were in 52% of them.
Therefore, the problem of functional (transient) disorders potential exists and is well established. In our country, this contributes to alcoholism and smoking low-quality grades of tobacco, chronic fatigue of the male population in the struggle for survival. The term "impotence" has now become used sparingly and it means (from Lat. Impotentia - weakness) of the complete absence of erection. To date, the effective medicines for the treatment of erectile dysfunction was not. MirSovetov not say that Viagra is a cure-all, it has only a temporary effect. But it is possible that on this basis in the future will create better products.

Viagra Viagra pills produces solid pharmaceutical company Pfizer. This is a film-coated tablets blue, diamond-shaped with the words «VGR 25» «VGR 50" or «VGR 100" on one side and «Pfizer» to another. The active ingredient of Viagra is sildenafil. The numbers on the tablets indicate how many milligrams of sildenafil is contained in 1 tablet of Viagra. The recommended dose is 50 mg for most patients, with the individual tolerance dose can be increased to 100 mg or decreased to 25 mg. Viagra is used not more than 1 time a day, about one hour before sexual intercourse. The tablet should be swallowed whole with a little water.
It is important, therefore MirSovetov once again underlines this point: the erection occurs only when there is sexual stimulation. The presence of the woman, intimate atmosphere will help you with this. Alcohol is not recommended to take, especially in large quantities, as not only the erection is lost, but the human face. And the next morning, it is advisable to remember who you spent the night. Abundant food, especially fatty food slows down the action of Viagra and the effect may be delayed. Older people (65 years and older) drug appears slower and long may circulate in the blood, so they recommend individual titration, usually downward.

In a review of 1473 cases of side effects of Viagra (data for one year). Of these 522 deaths: 94 men died of cardiac arrest, 200 people from myocardial infarction. Most often death occurs in the first 6 hours after dosing. The deceased suffered from cardio-vascular diseases of varying severity. It is believed that the cause of death in this situation is not the actual drug and sexual activity in people with heart disease. Situation turns ambiguous: on the one hand a person is ill and he may at any time happen heart attack, on the other hand, he takes Viagra, which is not suitable for his illness. Perhaps nature is wiser comes depriving these patients potency, thus taking care of the duration of their lives. Prove "guilt" of Viagra is almost impossible, so the company Pfizer has not lost yet no court case. Hence the action of Viagra, "core" must weigh the advantages and disadvantages, and discuss the use of Viagra with your doctor.

Overdose
Conducted research on volunteers - a single dose of 800
mg of Viagra. Adverse effects were more frequent and were heavier. No
specific antidote. In case of overdose symptomatic treatment is
recommended, usually in the intensive care unit. The matter is
complicated by the fact that dialysis (blood purification) in this
case is not effective as sildenafil tightly bound to plasma proteins
and is excreted in the urine.
Any negative impact on the ability to drive is not revealed, but given the possible side effects, some time after taking Viagra should be attentive to drive a car and operate machinery.

P.S. We still recommend to be careful with Viagra,
because the drug appeared on the pharmaceutical market is relatively
recent, and therefore poorly understood. There are no reliable large
randomized studies published in the press (mostly published or
laudatory article the manufacturer, or abusive articles competitors).
Do not take Viagra curiosity and aphrodisiacs. Remember that all
should be the measure and the "golden mean", if
continuously spur the body or certain functions, he will sooner or
later be exhausted and it will fail. It is possible that the frequent
use of Viagra, in the future you purely on a psychological level, can
not do without it, as the drug gives you more confidence in their
abilities.
And the last. Nobody canceled healthy life: learn harmony with nature, enjoy each day, be self-sufficient and then you do not need a blue pill.
