Is it true that Viagra was discovered by accident?

It was opened on purpose, but for a completely different purpose. Initially a pharmaceutical company developed drug for the treatment of arterial hypertension and angina pectoris. But during clinical trials, it turned out that the drug sildenafil affects the heart so-so, but it has a strong effect on the penis.

The company quickly realized what the benefits were. In 1998, the FDA (the federal agency that reviews all drugs on the US market) approved a drug called Viagra for the treatment of erectile dysfunction.

What is this big problem?

Yes, and what else. Erectile dysfunction is very commonespecially among men over 40 years of age. Due to stress, poor lifestyle, alcohol, smoking and diseases, sexual life becomes impossible. And this already leads to additional stress, a drop in self-esteem and serious problems in personal life.

And how does Viagra work?

Chemically, Viagra is the substance sildenafil, an inhibitor phosphodiesterase. This means that we have the enzyme phosphodiesterase in our body, which affects the blood flow in the cavernous bodies of the penis and in the vessels. If this enzyme is blocked, not allowed to act, then this very blood flow will increase.

This is how sildenafil works: it relaxes smooth muscles, blood vessels and increases blood flow to the penis. And this already helps to keep him in an erect state. Viagra is not heals cause of dysfunction, it simply eliminates the consequences.

Action has nothing to do with actual sexual desire. Viagra and PDE5 inhibitors (there are many trade names, it’s just that Viagra is the most advertised and has practically become a household name) help only in the technical part. But without desire, the pill may not work.

To whom is it prescribed?

“Viagra” is prescribed to men who are already 18 years old and who suffer from erectile dysfunction – for some reason they cannot have a sexual life due to the unavailability of the penis.

But in general, the active substance works to relieve the symptoms of pulmonary hypertension, but for these cases it is released in a different form.

And how is it received?

Most patients are prescribed a dose of 50 mg. It should be taken one hour before the intended sex. Not very convenient, but there is plenty of time for foreplay and erotic conversations.

But everyone reacts to the drug in their own way: 25 mg is enough for someone, and someone needs to increase the dose to 100 mg.

Elderly patients and those who have diseases of the cardiovascular system are advised to start with a small amount. doses in 25 mg.

It is better not to take more than one tablet a day, you should not take the drug with grapefruit juice. But you can take the drug for a long time, if you are not worried about side effects.

Can you drink alcohol with Viagra?

See how much. A glass of wine or a glass of beer will most likely not change the action drug. But an excess of alcohol can negate all the possible effect to increase potency.

Does the drug have any side effects?

Of course. In men suffering from cardiovascular diseases, the risk of heart attack or stroke increases when taking the drug. Viagra has a vasodilating effect, and sex is a cardio load, so patients with diseases should discuss the issue with their doctor, no matter how embarrassed you may be.

A separate side effect of Viagra is too long erection (more than 4 hours) and priapism. If such an effect is observed, one should immediately contact the doctors. Such prolonged tension of the penis can lead to damage to its tissues.

This is from dangerous states. In general, the drug list side effects (albeit rare) are impressive. There are banal dizziness, heartburn or indigestion, and more unpleasant pain when urinating.

Is it possible to go blind from Viagra?

Such a possibility exists. The fact is that the active substance of the pill affects not only the functioning of the penis, but also other organs. In some cases, it can act as a trigger that interferes with the blood supply to the optic nerve and causes optic neuropathy. nerve – a disease that impairs vision. It can even lead to blindness, but its course is individual.

If, while taking Viagra, you notice that you have begun to see worse with one eye (usually the disease begins with one eye), immediately quit the drug and run to be examined.

Who can’t take Viagra?

It is forbidden use Viagra if you:

  • take certain medications: nitrates (such as nitroglycerin), drugs to treat pulmonary hypertension, and a bunch more drugs. Therefore, the question of buying funds for potency should be discussed with a doctor;
  • suffer from blood pressure disorders;
  • suffered a heart attack or stroke;
  • suffer from diseases of the liver and kidneys;
  • suffer from diseases of the circulatory system;
  • suffer from a stomach ulcer;
  • have inherited retinitis pigmentosa (eye disease);
  • have a deformed penis.

I hesitate to buy. Maybe better…
