Cialis vs Viagra.
Comparison cialis viagra.
Viagra (Sildenafil Citrate)
is a medication made by Pfizer Pharmaceuticals, and is the first
approved non-surgical treatment for erectile dysfunction (ED)
that does not have to be either injected or inserted directly
into the penis to achieve and maintain an erection. It was approved
by the US Food and Drug Administration (FDA) for prescription
sale at the end of March, 1998.
Cialis (Tadalafil) is used to
treat male sexual function problems (impotence or erectile dysfunction)
by blocking a certain enzyme (phosphodiesterase-PDE5) in the body.
In combination with sexual stimulation, tadalafil helps blood
flow into the penis to achieve and maintain an erection.
