The two sides of Viagra

We will fulfill the desire of our readers and with the help of our specialists will tell you about the drug, which recently advertised so hard – Viagra. His popularity grew and almost everyone feels almost obliged to experience it.

How does it work?

The medicament dilates the blood vessels of the penis during sexual arousal. As a result, blood flow to the penis is increased, leading to a normal erection.

Like many other inventions, the effect of the drug was discovered by accident: in 1992 in clinical trials on volunteers a new drug to treat heart disease.

The drug is not given the expected results, but scientists turned their attention to the “side effect” – increased potency in men. Since 1998, Viagra was first appeared in pharmacies in the US.

Evidence

Viagra is a drug for treatment of erectile dysfunction. “This is a pathological condition in which the quality of erections in men can not provide normal sexual relations”, explain doctors. Usually these violations occur in men after 40 years. But often found in other age groups. Studies of the prevalence of erectile dysfunction have shown that by 1709 men aged 40 to 70 years, erection problems have 52 percent of them. Therefore, the problem of functional (transient) potency disorders actually exist and is quite widespread.

In our country the prevalence of this problem doprina-syat and alcohol, smoking, chronic fatigue accumulated in the struggle for survival. The term impotence now rarely used and represents a complete lack of erection.

To date, effective drugs for the treatment of erectile dysfunction will. Viagra is also not a panacea, it provides only a temporary effect. However, it is possible its basis in the future to create better products.

HOW TO TAKE VIAGRA TO NO HARM?

The active ingredient in Viagra is sildenafil. The figures show how the tablets mg sildenafil is contained in one tablet of Viagra. The recommended dose is 50 mg for most patients, but given the tolerance of an individual dose may be increased to 100 mg or less to 25 mg. Viagra is taken not more than 1 time per day, about one hour before intercourse. The tablets should be swallowed whole with a little water. It is desirable to avoid taking alcohol. Abundant eating, especially fatty foods, slows the effects of the medicine. In older people (65 years and more), the preparation is ejected more slowly from the body and longer remains circulating in the blood, therefore it is recommended in the individual doses are lower.

The blue pill is not for everyone

Viagra should not be used by children and adolescents up to 18 years. It is very important to know that this drug has been developed for the treatment of sexual dysfunction, and is not intended for use by healthy people. In other words, Viagra does not affect healthy people.

Overdose. A study was conducted among volunteers – a single dose of Viagra 800 mg.

Adverse reactions occurred more frequently and were more severe. There is no specific antidote. In case of overdose symptomatic treatment, often in intensive care conditions. The case is complicated by the fact that dialysis (blood purification) in this case is not effective, because sildenafil binds strongly to the proteins of the blood plasma and can not be discarded in the urine.

Not found any negative impact on the ability to drive, but because of the possible side effects for some time after taking Viagra should be careful when driving or operating machinery.

CAUTION!
We recommend that you be careful with Viagra as this drug appeared on the market relatively recently and therefore insufficiently studied. There have been no reliable large-scale studies that have been published in the press (mostly laudatory articles or published by the manufacturer, or extreme views, denying the usefulness of administration of the drug, competing companies). Do not take Viagra just out of curiosity and to enhance sexual sensations. Remember that everything must be measure and “golden mean” if constantly spurred organism or its separate functions, it will sooner or later be exhausted and there would be problems. Finally. Nobody has rejected a healthy lifestyle: Learn harmony with nature, enjoy every day and then you will not need the blue pill.

What are the contraindications

In fact, Viagra is a unique product for the treatment of impotence, easy to use, affordable and efficient. Yet there is another side to the coin. Everyone knows that before a new drug should read the instructions for its use, or the notes. It is best to consult a doctor, to discuss the dose and duration of application, and possible side effects. There can be no false shame. You must be aware of the contraindications before taking the drug:

If taking regularly or intermittently nitrates to treat angina pectoris (e.g. nitrosorbit, kardiket, izoket etc.), and nitrogen donor oxide. In these cases, use of Viagra is contraindicated because it enhances the effect of nitrates and blood pressure can drop to critical limits. If you do not know whether drugs that drink belong to the nitrate – ask your doctor to avoid future problems. Caution should be used in the presence of Viagra anatomical deformity of the penis, diseases accompanied by bleeding, where exacerbation of an ulcer of the stomach and duodenum in the first 6 months after myocardial infarction, stroke, in severe arrhythmia. If blood pressure is above 170/100 or lower than 90/50 refrain from taking Viagra.

Side Effects

Worthy of interest and side effects from the effects of Viagra – for them you also need to know:

– A rush of blood to the face – in 10.9% of cases;
– Palpitations – 1%;
– Severe headache – 10.8%;
– Disorders of perception in color vision: the world is colored mostly in blue, increased eye sensitivity to bright light;
– Nasal congestion – 2.1%;

malfunction of the stomach, vomiting – 3%;
– Lowering blood pressure, seizures, bleeding from the nose;

It may appear too painful erection lasting – up to 4 hours, requiring emergency medical intervention.

A study of 1473 cases of severe complications after the use of Viagra (data for 1 year). Of those 522 deaths, 94 men who died of a heart attack, 200 people from myocardial infarction. Most often death occurred during the first 6 hours after taking the drug.

Dead men suffered from cardiovascular disease with varying degrees of severity.

It is believed that the cause of death in this situation is not the drug itself, and sexual activity in people with heart diseases. The situation is not straightforward: on the one hand, if a person is sick, he at any time may have a heart attack, on the other hand, he takes Viagra, which is contraindicated in such diseases. Perhaps nature has solved this problem very wisely, depriving such patients potency, thereby taking care of their lifespan. To prove the “guilt” of Viagra in such cases is almost impossible. Therefore sardechnobolnite patients should carefully weigh all pros and cons and discuss the use of Viagra with your doctor.

British researchers studied the effects of Viagra on mice. It turns out that it reduces the likelihood of conception by 30% since the sperm can not penetrate the egg – all substances they need for this purpose have been spent in advance. No evidence of an effect of administration of the drug in humans. The company claims that the drug does not affect the generative function and even improving it.
