Viagra effects on erectile function (clinical studies)

Viagra helps many men (4 out of 5 men) with erectile dysfunction to respond adequately to sexual stimulation. When a man is sexually aroused, Viagra enables the penis to fill with enough blood for an erection. After sex is over, the erection goes away naturally.

In eight large double-blind, placebo-controlled crossover studies of adult male patients with erectile dysfunction induced by different factors, the use of Viagra with sexual stimulation improved erections. Special evaluation was done by RigiScan allowing objectively assessing hardness and duration of erections produced by Viagra.

The efficacy of Viagra was observed approximately 45- 60 minutes post dose. Still some men experienced the effect within 30 minutes post dose. The erectile response generally increased with the dose increases. Still the side effects occurrence also increases with the increases in the dose. The Viagra effect as assessed in most studies was up to 4 hours.

Viagra dosage and administration

Viagra is produced in different doses (25 mg, 50 mg and 100 mg of Sildenafil), this allows to find the proper dose for each patient. The starting dose for most patients is 50 mg, it is recommended by the doctors and most experts. Still some of the doctors advise to start with the lowest dose, it can be as well effective. If a patient does not achieve the desirable results, a doctor usually increases the dose.

Before the treatment is started it is very important to determine the right dose which will work for you individually and will be safe for your health.

Remember, that Viagra is a potent drug, never take more than your doctor prescribes. Viagra should not be taken more than once a day (24 hours should pass between doses).

A lower dose of Viagra is prescribed for certain groups of patients, including:

  • Geriatrics, men over the age 65. They may be more sensitive to the action of the drug.
  • Men who have serious liver or kidney problems. Doctors usually prescribe them the lowest dose (25 mg) of Viagra. Sometimes, more time between doses is needed (48 or even 72 hours).
  • Men taking protease inhibitors are also recommended to take a 25 mg dose in a 48 hour period.
  • Men with enlarged prostate or hypertension who take other medicines (alpha blockers) also receive the lowest dose of Viagra for ED.

Viagra is taken about 30-60 minutes before sexual activity. Some men can notice that the drug works within 15 minutes after dose. The effect can last up to 4 hours.

Viagra should be taken on an empty stomach to get the results. Take the drug with full glass of water.

For whom Viagra is designed?

Originally Sildenafil was designed for people with heart problems, but the researchers observed its properties in improving erectile function. Viagra is not for everyone. It is indicated and prescribed only for those men who have been diagnosed with erectile dysfunction or impotence. Viagra is not indicated to be used in women for the purposes of improving libido. Viagra is not indicated to be used in children. Serious side effects may occur if the drug is taken wrong.

Men who experience erectile dysfunction periodically should consult their doctors about the possibility of Viagra use. Men who have persistent problems with erections can choose Viagra treatment as a very effective and verified by time.

Males who experience other unrelated conditions have to take the lower dose of the drug.
