Viagra (Sildenafil)

Viagra is a drug developed by Pfizer that helps relax muscles and dilate blood vessels. As a result of taking sildenafil, local blood circulation is activated, and long-term maintenance of an erection is ensured. Considering that the active substance of the drug affects all organs, it must be taken with caution and as prescribed by a doctor.

Viagra (sildenafil) is used to treat male impotence. Viagra is one of the most common drugs based on sildenafil, which in society refers to the entire group of drugs for erectile dysfunction (ED).

For what conditions or diseases is Viagra prescribed?

Viagra is prescribed for erectile dysfunction and pulmonary arterial hypertension (high pressure in the vessels supplying blood to the lungs).

The drug helps improve the quality of sexual life, normalize blood circulation in the lungs, and reduce the load on the heart.

Also, when taking sildenafil, there is an improvement in well-being, self-control, and a decrease in depressive symptoms, which has a beneficial effect on relationships with a partner.

How does Viagra work?

Sildenafil has an inhibitory (blocking) effect on an enzyme called phosphodiesterase type five (PDE-5), which leads to relaxation of the vascular smooth muscles in the cavernous (cavernous) bodies of the penis.

For erection problems, sildenafil temporarily increases blood flow to the penis when you are sexually aroused. Also, after using Viagra, there may be a reduction in the refractory period (the break between two sexual acts) by about 10 minutes.

Does Viagra treat erectile dysfunction?

Viagra can be prescribed to treat erectile dysfunction since the use of the drug increases the frequency of erections sufficient for sexual intercourse. Sildenafil also treats sexual dysfunction by increasing pleasure and satisfaction in sexual life.

When using Viagra, it is necessary to take into account that taking sildenafil by itself does not cause an erection. You must be sexually aroused for the drug to work.

Problems with potency arise due to insufficient filling of the penis with blood.

Sildenafil ensures blood flow to the penis, but the causes of erectile dysfunction may be pathologies that require separate treatment (for example, atherosclerosis, Peyronie's disease, or diabetes).

How to take it correctly?

The usual dosage of Viagra for erectile dysfunction or impotence is 25 or 50 mg. The maximum daily dose is 100 mg. Adults under 65 years of age can drink 50 mg no more than once a day; at older ages, the permissible daily dosage is reduced to 25 mg.

Viagra works more effectively when taken on an empty stomach an hour before sex, but it also works when taken after a meal. It begins to act within half an hour, the effect can last up to four hours, although it usually decreases after 2 hours.

The likelihood of side effects increases with overdose. For example, the following case is described: in 2019, one man took 750 mg of Viagra, more than 10 times the recommended dose. He stopped seeing, and circles appeared in his eyes.

The doctor diagnosed a retinal lesion that could not be treated. It is unknown whether the man’s vision returned since he no longer appeared in the hospital.

Combining Viagra with alcohol can also lower blood pressure.

How quickly does Viagra take effect?

The onset of action of Viagra is 15-60 minutes after taking the drug. In approximately 35% of men, the drug is active within the first quarter of an hour. The effect of sildenafil occurs only with prior sexual stimulation and may increase with increasing doses.

How long does Viagra last?

The effect of taking sildenafil lasts about four hours, which corresponds to the half-life (breakdown in the liver) of the active substance of Viagra.

A gradual decrease in the concentration of sildenafil in the body occurs over the next 20 hours.

How quickly Viagra works may depend on the presence of concomitant diseases. For example, with liver or kidney diseases, the rate of action of the drug may be reduced.

Side effects

Many medications have side effects. Viagra is no exception. If a man suffers from cardiovascular diseases and has an increased risk of stroke and heart attack, then taking the drug in his case is strictly prohibited.

Viagra has a vasodilating effect, and sexual intercourse is a serious cardio load. Therefore, if a man has problems with the diseases described above, then before taking the drug, he needs to consult with his doctor.

The pills also have a separate side effect that many have heard about - an erection that lasts too long, which can last for 4 hours.

In this case, the man experiences pain in the genital organ. If exactly this effect occurs, you must immediately go to the nearest clinic for examination by a specialist. If the penis is kept under tension for such a long time, it can cause tissue damage.

These are only the most dangerous conditions that can be achieved if the drug is taken incorrectly.

But there is also a fairly impressive list of side effects of Viagra, which are rare. These include dizziness, indigestion, heartburn, as well as uncontrolled urination, and minor pain in the genitals.

What precautions should you take while taking Viagra?

When taking sildenafil, you must strictly adhere to the dosage prescribed by the urologist, taking into account your personal history. Other precautions when using Viagra:

• careful study of the annotation for the drug;
• preliminary informing the doctor about the presence of concomitant diseases (for example, heart disease);
• avoiding consumption of grapefruit or grapefruit products at the same time as Viagra.

It is also necessary to monitor the compatibility of Viagra with other medications. If side effects occur, you should stop taking the drug and consult a urologist.
