HOW DOES VIAGRA WORK?
Viagra is the brand name for sildenafil. When sexual stimulation begins
nitric oxide (NO) is released into the spongy tissue of the penis. NO
then activates an enzyme that increases the production of cyclic guanosine
monophosphate (cGMP) the substance that relaxes the spongy tissue of the
penis and facilitates an influx of blood. As specific enzymes slowly degrade
cGMP the penis will slowly loose its ability to sustain an erection. Viagra
works by inhibiting those enzymes that degrade cGMP, thereby enhancing
ones ability to obtain and sustain an erection.
HOW EFFECTIVE IS VIAGRA?
Over 21 studies have been done to evaluate the efficacy of Viagra. Evaluation
of drug activity was most often done using a self-assessment questionnaire.
During a 6-month open labeled study, Viagra was found to improve sexual
function in 88% of those treated. This included frequency, firmness, and
maintenance of an erection; frequency of orgasm; frequency and level of
desire; frequency, satisfaction and enjoyment of sexual intercourse; and
overall relationship satisfaction.
WARNINGS:
If you take any medicines that contain nitrates - either regularly or
as needed - you should never take Viagra.
If you take Viagra with any nitrate medicine or recreational drug containing
nitrates, your blood pressure could suddenly drop to an unsafe level.
You could get dizzy, faint, or even have a heart attack or stroke. Nitrates
are found in many prescription medicines that are used to treat angina
(chest pain due to heart disease) such as: nitroglycerin (sprays, ointments,
skin patches or pastes, and tablets that are swallowed or dissolved in
the mouth), isosorbide mononitrate and isosorbide dinitrate (tablets that
are swallowed, chewed, or dissolved in the mouth). Nitrates are also found
in recreational drugs such as amyl nitrate or nitrite ("poppers").
If you are not sure if any of your medicines contain nitrates, or if you
do not understand what nitrates are, ask your doctor or pharmacist.
