Prescriptions Solution To Erectile Dysfunction, But Is It Safe?
By www.menhealthonline.biz
VIAGRA is a prescription medicine for erectile dysfunction (ED). Viagra was the first in a range of proscription drugs, which has been shown to work for most men with erectile dysfunction. If you have ED, this can help you get an erection and maintain it during sexual activity. Viagra only works when you are sexually aroused, after sex, your erection will go away.
Brief History.
The drug was patented in 1996, approved for use in erectile dysfunction by the Food and Drug Administration on March 27, 1998, and offered for sale later that year. The British press portrayed Peter Dunn and Albert Wood as the inventors of the drug, a claim which Pfizer disputes. Their names are on the manufacturing patent application, but Pfizer claims this is only for convenience. Viagra has been extensively tested in over 4500 men prior to its approval by the FDA. Other drugs that operate by the same mechanism include tadalafil (Cialis®) and vardenafil (Levitra®).
Viagra has become a generic term for many people discussing drugs designed to treat erectile dysfunction and as with all prescription drugs, proper dosage is at the discretion of a licensed medical doctor. Many herbal products marketed as sexual stimulants claim to be "natural versions" of Viagra, but they are not the same as the prescription drug. No herbal products as yet, has proved to be as specific for blood vessels to the penis as Viagra and other similar prescription drugs.
The Effects
The effects of Viagra can last up to 4 hours, but the response at 4 hours is less than at 2 hours after consumption. Erections lasting for more than 4 hours can occur albeit rarely, as with all ED treatments in this drug class, to avoid long-term injuries, it is important to seek medical advice.
Viagra is also informally known as "Vitamin V", "the Blue Pill", as well as various other nicknames. Viagra is available to most offline and online pharmacies. You take Viagra orally (maximum once per twenty-four hour period) about 30 minutes to one hour before sexual activity. It is available as oral tablets in 25mg, 50mg and 100mg strengths.
