testimony

Model Viagra molecule
Viagra - a a drug for the treatment of erectile dysfunction. That's just what this state really no one knows. The most frequent response professionals, "a pathological condition in which the quality of erections in men is reduced and as a consequence - the impossibility of full sexual intercourse."

Most often these disorders occur in men over 40years. However, they often occur in other age groups. Research on the prevalence of erectile dysfunction are many and in Russia and abroad. The most accurate is considered "aging study program at the Massachusetts men." In a survey of 1709 men aged 40 to 70 years of erection problems in one way or another appeared in 52% of them.

Therefore, the functional problem (transient)potency disorders really exists and is quite widespread. In our country, this contributes to low-quality alcohol and smoking tobacco varieties; chronic fatigue male population in the struggle for survival. The term "impotence" is now has been used rarely, and it means (from the Latin Impotentia -. Weak) complete absence of erection. Hitherto effective medicines for the treatment of erectile dysfunction was not. Our website does not say that Viagra is a panacea, it has only a temporary effect. But it is possible that it is based on more sophisticated formulations will be created in the future.

application

Viagra Tablets
Viagra produces a solid pharmaceutical firmPfizer. This film-coated tablets blue, «VGR 25» «VGR 50" diamond-shaped with an inscription or «VGR 100" on one side and «Pfizer» on the other. 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 the majority of patients, given the individual tolerance dose can be increased to 100 mg or decreased to 25 mg. Viagra is used no more than 1 time per day, about one hour before sexual intercourse. The tablet should be swallowed whole with a little water.

It is very important, because our site again emphasizethis point: the erection occurs only when there is sexual stimulation. The presence of the woman he loved, intimate atmosphere will help you with this. Alcohol is not recommended to take, especially in large quantities, since not only the erection is lost, but also a human face. And in the morning, it is desirable to remember with whom you spent the night. Abundant food, especially fatty foods 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 selection of doses, usually downwards.

In fact, Viagra is the only drug of its kind to impotence treatment, Easy-to-use, affordable and sufficienteffective. However, there is another side to the coin. All following our site recommends that you read with special attention, so as not to harm their health in the future.

Everyone knows that before you begin taking a newthe drug must read the instructions for its use or annotation. It is best to consult a doctor: to discuss the dose, frequency and duration of use, as well as possible side effects. There should be no false shame. You should be aware of contraindications to Viagra:

Analysis was conducted in 1473 the incidence ofside effects of Viagra (data for 1 year). Of these, 522 deaths: 94 men died from cardiac arrest, 200 people from myocardial infarction. Most often death occurred within the first 6 hours after ingestion. Who died suffered from cardiovascular diseases of varying severity system. It is believed that the cause of death in this situation is not self cure, and sexual activity in people with heart diseases. The situation turns ambiguous: on the one hand a person is sick and he had a heart attack can occur at any time, on the other hand, he took Viagra, which is not suitable for his illness. Perhaps nature more wisely goes depriving such patients potency, thereby taking care of the duration of their lives. Prove "guilt" of Viagra is practically impossible, so Pfizer is not yet lost a single court case.
The action of Viagra
Consequently, the "cores" is necessary to weighthe pros and cons and discuss the use of Viagra with your doctor. The instructions to the drug in a separate line says: "drugs for the treatment of erectile dysfunction, should not be given to men for whom sexual activity is not desirable."

British scientists studied the effect of Viagra in mice. It turned out that it reduces the likelihood of conception 30%, sperm can not penetrateegg, since all the substances they need to do is spent before. On a similar effect in humans no data. The company itself states that the drug has no effect on reproductive function and even improve it, contributing to copulation.

Viagra should not be used for children and youths up to 18years. It is very important that this drug was designed to treat fairly pronounced sexual disorders and is not intended for use by healthy men. In other words, Viagra has no effect on healthy individuals. But if a person who considers himself healthy after taking the pill improved erectile function, it is quite possible he may suffer some "hidden" erectile dysfunction.

Overdose

Viagra
In volunteers conducted the study -single dose of Viagra 800 mg. Adverse effects were more common and harder. No specific antidote. In case of overdose symptomatic treatment is recommended, often in conditions of 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 proteins blood plasma and not excreted in the urine.

Any negative impact on the ability ofto drive is not revealed, but in view of possible side effects, some time after taking Viagra should pay more attention to road management and operation mechanisms.

P.S. Our website recommends nevertheless be careful with Viagra, because the drug appeared in the pharmaceutical market is relatively recent and, consequently, poorly understood. No reliable large randomized trials published in print (mainly published laudatory articles or most of the manufacturer, or abusive articles competitors). Do not take Viagra for the sake of curiosity and enhance sexual sensations. Remember that all should be the measure and the "golden mean"; if constantly spur the body or some of its function, it will sooner or later be exhausted and fails. It is possible that frequent use of Viagra in the future you purely on the psychological level will not be able to do without it, as the drug gives you more confidence.

And the last. Nobody has canceled a healthy lifestyle, learn the harmony in nature, enjoy each day, be self-sufficient and then you do not need a blue pill.
