Viagra
There are a variety of oral treatments for erectile dysfunction. One of them is Viagra, also known as Sildenafil. Erectile dysfunction by definition is the inability to have or maintain an erection. There are medical and psychological reasons for this. Most commonly it is a medical reason such as diabetes, neurological, circulatory or urological conditions. Viagra is one of the most common prescription treatments. It is also known as Revatio.
According to Medline Plus Drug Information (a service of the US National Library of Medicine and the National Institutes of Health) Sildenafil works to control the release of the enzyme phosphodiesterase. By controlling this enzyme the patient is able to have an erection when the penis is stroked during sexual intercourse. It will not cause an erection any other time.
This like many other phosphodiesterase inhibitors has not been tested nor is it recommended for women. This includes women who or who may become pregnant and women who are breastfeeding. Be sure to tell your doctor if you have allergies other substances or to certain foods or dyes or if you have an allergic reaction to Viagra.
Older patients who are already taking medication for pulmonary arterial hypertension may need to start at a lower dosage. Also patients must notify their doctor of all over the counter and prescribed medication they are taking. Viagra does interact with other medications such as: Erythromycin, alpha-blockers and other erectile dysfunction medication. It is not recommended that Viagra be taken with other oral impotence treatments.
Viagra comes in 25 mg, 50 mg, and 100 mg tablets. Revatio is available in 20 mg tablets and is used in the treatment of pulmonary arterial hypertension (continuous high blood pressure in the pulmonary artery).
It is recommended that it be taken without food to speed up the absorption rate.
