Sildenafil Review for Persistent Erection and Widening of Blood Vessels

Sildenafil – is the most bought drug for excitement around the world. Sildenafil effectively combats erectile dysfunction in men and maintains a penis hardness sufficient for sexual intercourse. It has a beneficial effect on blood circulation in the pelvic region, which contributes to the expansion of blood vessels.

Even in serious pathologies such as spinal cord injuries, prostate surgery, diabetes, and other diseases that negatively affect sexual function, it provides excellent results. Wide popularity and sales statistics in pharmacies confirm the high effectiveness of the drug in eliminating sexual problems.

Since 1977, American pharmacologists have been working on the development of a substance that could narrow and expand the blood vessels in the heart, brain and lungs. This lasted until 1992, the year scientists began testing Sildenafil Citrate. Until then, however, there were no noticeable results from their work. The tests were conducted with the aim of creating a drug for the treatment of diseases of the cardiovascular system.

Sildenafil citrate exhibited an unexpected property of blocking certain enzymes. This led to a widening of the blood vessels in the area of ​​the genitourinary system. The substance caused a persistent and long-lasting erection, which pleasantly surprised the men in the tests.

Then the substance was examined in a different direction. As a result, all known Viagra tablets appeared in 1998. Sildenafil received three scientists the Nobel Prize for creating medication to treat heart and lung disease in the same year. The makers of Viagra had developed a drug with Sildenafil that would prove groundbreaking.

Indications and composition

Sildenafil is released in the form of citrate. Shelf life is two years.

The main form of release – tablets, continuously doses the active ingredient in 25mg, 50mg, or 100mg. In classic Viagra, the tablets have a diamond-shaped, convex shape, and the pills are covered with a recognizable blue coating. Equals of the drug, of which a wide range is available, are produced not only in tablets but also in the form of powder, capsules (100 mg), and drops. In one package, Sildenafil can contain 1 to 12 tablets.

In addition to the basic substance, the preparation contains such auxiliary components as povilone, cellulose, magnesium stearate, lactose monohydrate and some other ingredients.

Mechanism of the Action

Sildenafil is classified as a selective inhibitor of PDE-5 (type 5 phosphodiesterase). The principle of its action is based on the widening of blood vessels in the genitals and the increase in blood flow to the penis.

This makes it possible for men to get a good and prolonged erection. Buying Sildenafil can eliminate problems with erectile function manifested by the inability of the penis to maintain the necessary hardness for sexual contact. This effect of the drug is due to its ability to affect the enzymes responsible for achieving a penile erection.

However, as mentioned before, tablets cannot stimulate an erection on their own if there is no sexual attraction to the partner. If there is a natural desire, the excitement increases, and Sildenafil will be able to support this excellently.

The drug restores the lost response to sexual arousal. Normal erections are impossible without the release of nitric oxide in the erectile tissues of the penis, which activate the enzyme guanylate cyclase. Its activation involves an increase in the specific nucleotide – cyclic guanosine monophosphate (cGMP), which is necessary to relax the muscles of the cavernous body, resulting in increased blood flow to the penis.

Indications for the use of the drug are not only erectile dysfunction but also pulmonary hypertension. The drug expands the vessels in the respiratory organs and reduces their pressure. Thanks to this remedy, respiratory problems in people with this disease are significantly reduced, and shortness of breath is also reduced.

In addition, the ability of the drug to reduce pressure has been proven. However, this effect only lasts during the action of the tablets, and after completion, the pressure is restored to the previous values.

Indications and Features

The drug Sildenafil should preferably be taken one hour before intimacy. Do not be afraid that the drug will act prematurely, because the effect of its use in men comes on only with natural sexual arousal.

If there is no desire for a partner, then – as it should be – no erection will occur. If you have to choose between doses of 25mg, 50mg, or 100mg, you should consult a specialist who will prescribe the required concentration of the substance based on the patient’s characteristics.

As a general rule, 25-50 mg will be sufficient as a starting dose. Instructions for using the drug contain the maximum daily dose, which should not exceed 100mg. It is not recommended to take the maximum amount the first time. It is recommended to rinse the tablets with a large amount of water, as they have a specific taste.

The duration of the remedy is 5 hours, and the adequate time of action is between 4-and 6 hours. The effect of taking medication remains in men throughout sexual contact, and it supports the natural ability to perform sexual intercourse healthy and energetically. In case of the repeated desire for intimacy before the appearance of an erection, no further use of the drug is necessary.

Tablets can be consumed on a full or empty stomach, but it should be taken into account that the absorption of this drug will take 20-25 minutes longer after consuming fatty foods. Viagra and its generic variants (Sildenafil Medan, Maxigra, etc.) can be combined with a moderate dose of alcohol.

Pulmonary hypertension Indication

Using 100mg tablets for this application is not convenient as the recommended dose is usually 25mg 3 times a day – at 7-8 hour intervals. There are tablets with smaller doses that are better suited for this.

If someone tolerates the drug well, the dose can be increased to 50mg at a time. However, it is not necessary or advisable to use more than 100mg per day without a doctor’s instructions.

Older people should take this medicine at a dose of only 25 mg. The same goes for men and women who suffer from kidney and liver diseases. If the body poorly tolerates the drug, a daily dose of 100mg is not recommended. 50mg per day is more sensible, divided into two doses of 25mg.

Sildenafil for women

Recently, Viagra and its analogs can be used more and more to eliminate intimate problems for men and the fair sex. Their effectiveness in women has been proven even at menopause and after removing the uterus.

Due to the use of drugs, such effects were found in the fair sex:

  • increased libido;
  • sensuality enhancement;
  • reduction of the time during which arousal occurs;
  • increased vaginal moisture;
  • improving blood circulation in the genital area;
  • increased sensitivity in erogenous zones;
  • increased duration of orgasm;
  • elimination of frigidity;
  • increased sexual desire in older women;
  • increased stamina with intimacy.

Tablets have a complex effect on women because they stimulate sexual attraction to the sexual partner and intensify arousal. Increased blood flow in the pelvic organs contributes to greater sensitivity and clarity of feelings during intimacy. Thanks to this preparation, the vagina is naturally much better moistened. Therefore its use is recommended in case of vaginal dryness.

Ventricular Extrasystole and Medication Use

For people who have had heart problems, its use carries an increased risk and should only be used under supervision. Ventricular extrasystole is another pathology where using Sildenafil can be dangerous. It is a disease associated with cardiac arrhythmias and the appearance of additional impulses in the heart. The following symptoms accompany pathology:
