 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.
