Both
Viagra and Cialis work to relax the muscle that can
block blood flow to the penis. Without this blood flow
there is no erection. So if this muscle is not regulated,
you get no ejection.
Dosage
Cialis drug information
Cialis comes in smaller doses of 5mg, 10mg and 20mg
whereas Viagra is available in the strengths of 25mg,
50mg, 100mg.
Works Faster
Cialis also works much faster than Viagra- in about 15 minutes instead of half an hour taken by Viagra to work.
No food and Alcohol constraintsCialis can be taken
without food and alcohol constraints. You can eat
whatever you want to while taking Cialis because food
does not inhibit the effectiveness of the drug. With
Viagra you're required to limit your consumption of
fatty foods because it slows down the onset time.
Side Effects
Test results have also shown that Cialis has no adverse
side effects on vision or the heart. It's believed
that Cialis is more selective than Viagra at targeting
PDE5 receptor sites. Besides controlling blood flow
to the penis, PDE5 enzymes play in essential role
in the action of cells in the brain, heart, kidney,
and eyes.
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.
Lasting power
Cialis has an effective time of up to 36 hours after taking one pill. This is much longer than the four hours of Viagra. So you get more sex out of Cialis.
Cialis is a better treatment
option for diabetics!
Cialis works better for patients with diabetes. In
clinical studies the effectiveness of Cialis
in patients with diabetes did not decline. However,
with Viagra, the effectiveness of the drug dropped
by almost 50 percent!
