What is Viagra medication

The medication Viagra manufactured by Pfizer International Inc. is the first pharmaceutical drug in tablets to be taken by mouth that is effective for the most of men suffering erectile dysfunction. The active substance of Viagra is called Sildenafil Citrate.

The medication is manufactured in form of tablets with dosage of 25, 50 and 100 mg that contain respectively 25, 50 and 100 mg of Sildenafil Citrate.

Unlike other methods of erectile dysfunction treatment which involve making injections in the male penis or other medical procedures, Viagra is a very easy to take, practical and and simple to use drug. While on Viagra treatment, you just need to take one tablet 30 to 60 minutes before the sexual intercourse.

Concerning the mechanism of action of Viagra, it consists in increasing the blood flow that goes to the penis which helps a man to have a natural erection. Viagra acts only when a man is under the natural sexual arousal. When the sexual intercourse is over, the male penis comes back to its natural relaxed state. In other words, Viagra influences only the natural mechanisms of erection origins that makes it an absolute novelty and very successful in the world.

You should be aware that Viagra is not an aphrodisiac, therefore, without sexual stimulation, it will not have an erectile effect.

As any medication, Viagra is sold in drug stores. We strongly advise to not buy Viagra without prior consultation with the doctor who will inform you about the right dose for your personal case and will issue you a prescription. Besides drug stores, Viagra is sold directly from the doctors dealing with erectile dysfunction treatment. Please be cautious to not buy Viagra from untrusted sources to avoid having a surrogate medication that, in the best case, doesn't have any effect on erection.
