Information on Viagra For Male Impotence TreatmentWhat is ViagraŽ?
ViagraŽ is the first significant oral medication for the treatment of male impotence. Viagra was originally developed as a cardiovascular medicine designed to improve blood flow in the vessels of the heart. However, during initial studies Viagra was found to have a profound side effect. Individuals began to report a remarkable difference in their ability to achieve and maintain an erection. The significantly enhanced erections prompted Pfizer to develop Viagra as a male impotence treatment.

ViagraŽ is dispensed as a pill and ingested orally. Approximately 30-60 minutes later the drug is absorbed in the bloodstream. ViagraŽ then functions as an inhibitor to an enzyme called phosphodiesterase type (PDE5) which is found primarily in the penis. By inhibiting PDE5, smooth muscle in the penis remains relaxed for a longer period. This allows for increased blood flow into the cavernous tissue of the penis thereby generating an erection. ViagraŽ is unique in that it increases a natural occurring process, therefore, only through sexual stimulation will an erection occur.
What is the appropriate dose of Viagra?
The standard dose is 50mg one hour prior to sexual activity. However, if you are older than age 65 or have a serious kidney or liver disease some physicians will recommend starting with the minimal dose of 25mg. ViagraŽ should not be taken more than once per any 24-hour period and doses should not exceed 100mg. Most doctors recommend purchasing the Viagra 100mg tablets and splitting them in half for a considerable savings. Pfizer charges the same price for all three doses of Viagra: Viagra 25mg, Viagra 50mg and Viagra 100mg tablets.
What clinical studies have been done with regards to Viagra?
Fortunately, there is now a proven way to treat impotence. Viagra has been tested in over 130 clinical trails involving men of all ages.

What happens if there is no sexual stimulation following the ingestion of ViagraŽ?

What are precautions/warnings concerning ViagraŽ?
Men who are taking medicines that contain nitrates (Nitroglycerin) of any kind must never use ViagraŽ. Patients should not take ViagraŽ even if you only take nitroglycerin medication occasionally. (Please see list of nitrates) There is also a potential for cardiac risk during sexual activity in patients with preexisting cardiovascular disease. Therefore, ViagraŽ should not be used in men where sexual activity is inadvisable because of their underlying cardiovascular status. Several medications are known to interact with ViagraŽ. Therefore, one should inform their physician concerning all medications they are taking, including those medications acquired by a prescription as well as over the counter medicines. The use of ViagraŽ offers no protection against sexually transmitted diseases, including HIV. Patients should continue to use protective measures necessary to guard against these diseases. In case of an overdose, call your physician immediately.
Can I use ViagraŽ with other medications?
Yes, it is generally safe to use ViagraŽ while on other medications, however some medicines may potentiate the effects of ViagraŽ. Individuals should always consult with their healthcare provider prior to taking any medication. Note ViagraŽ does have one absolute contraindication; individuals who are taking medication-containing nitrate (even intermittently) should not take ViagraŽ.
Why is ViagraŽ absolutely contraindicated in individuals who are currently taking medications containing nitrates?
ViagraŽ has been shown to potentiate the hypotensive effects of nitrates to life threatening levels. Therefore, individuals who are currently using nitrates in any form even intermittently should not take ViagraŽ. Nitrates are available in many medications; sprays, ointments, skin patches, pastes and tablets dissolved in the mouth. Nitrates are also found in illicit drugs such as amyl nitrate or nitrite "Poppers". If you are unsure if you are currently taking nitrates please value your health and consult with your local physician or pharmacist.
For what types of ED is ViagraŽ proving to be especially effective?
ViagraŽ is showing optimal results in individuals who experience impotence secondary to high levels of anxiety (performance anxiety) and individuals with mild impotence secondary to physiologic causes..
Is ViagraŽ less effective in treating ED that is secondary to certain underlying medical conditions?
This question is somewhat difficult to answer right now. More data is expected in the near future. Some initial data suggests that men, who have undergone radical prostatectomy (surgical removal of their prostate), using nerve-sparing procedures, are not achieving the same positive results with Viagra.
