About impotence:
Experts believe impotence affects between 10 and 15 million
American men. In 1985, the National Ambulatory Medical Care
Survey counted 525,000 doctor-office visits for erectile
dysfunction. Impotence usually has a physical cause: such as
disease, injury or drug side effects. Any disorder that impairs
blood flow in the penis has the potential to cause impotence.
Incidence rises with age: about 5 percent of men at the age of
40 and between 15 and 25 percent of men at the age of 65
experience impotence. However, it is not an inevitable part of
aging.
What is Sildenafil Citrate?
Sildenafil Citrate is an active ingredient of the most popular
ED drug. Sildenafil Citrate is designated chemically as
1-[[3-(6,7-dihydro-1-methyl-7-oxo-3-propyl-1H-pyrazolo[4,3-d]pyri
midin-5-yl)-4-ethoxyphenyl]sulfonyl]-4-methylpiperazine citrate.
Sildenafil citrate is a crystalline powder with a solubility of
3.5 mg/ml in water.
How does Sildenafil Citrate Help?
Sildenafil is used a treatment for men experiencing erectile
dysfunction (difficulty maintaining an erection). Sildenafil's
mission is to work on enzymes of the body called
phosphodiesterases and to improve a man's response to sexual
stimulation. These enzymes work mainly in the penis, so the
action of sildenafil citrate is primarily limited to the penis.
Sildenafil works to control the enzyme, and by doing so
regulates the blood flow out of the penis and thereby helping
the patient maintain an erection. Sildenafil citrate improves
the erection of most men, regardless of how long they have had
ED. So the time spent with one's partner can be sexually active
and arousing.
Side Effects:
The most common side effects of Sildenafil citrate are headache,
flushing of the face and upset stomach. Less common side effects
that may occur are temporary changes in color vision (such as
trouble telling the difference between blue and green objects or
having a blue color tinge to them), eyes being more sensitive to
light or blurred vision. In rare instances, men have reported an
erection that lasts many hours. You should call a doctor
immediately if you ever have an erection that lasts more than 4
hours. If not treated right away, permanent damage to your penis
could occur
