Viagra originally developed
to treat angina sufferers was later discovered
to help the cause of erectile dysfunction. Cialis
is also a revolutionary new drug used to treat
Erectile Dysfunction.
Viagra
increases blood flow to the penis, so that when
sexually excited, a man can get and keep an erection.
The erection goes away when the sexual encounter
is over. Viagra works in about 30 minutes and
lasts for at least 4 hours. Cialis works faster
than Viagra - in about 15 minutes instead of half
an hour. It lasts a lot longer, helping men get
erections for 24 hours vs. the four-hour window
Viagra provides.
When a man
is sexually aroused, certain tissues in his penis
relax. This allows large amounts of blood to flow
in, thus producing an erection. Viagra helps by
elevating the levels of the chemical that causes
the tissues to relax. Cialis works chemically
in the same way as Viagra, but erection is achieved
more quickly using a smaller dose. It also lasts
much longer.
Viagra achieved
a success rate of 60-80 per cent, depending on
the dosage, in trials. However, it doesn't always
work first time as claimed by some. On the other
hand, Cialis impotence pill lasts longer than
Viagra and has more spontaneity.
Blue discoloration
of vision (overlap with PDE-6 in the retina) is
seen only with Viagra (<0.5%) and muscle aches
only with Cialis. Viagra can cause some visual
problems, including, an increased sensitivity
to light, blurred vision, or an inability to tell
the difference between blue and green. Cialis
comes without some of the side effects that have
been associated with Viagra. However, many men
on the drug complained about 'facial flushing',
others said it didn't work after a meal, while
some complained that the drug turned their vision
blue.
