Levitra vs Cialis.
Comparison levitra cialis.
Levitra (Vardenafil hydrochloride)
is an FDA-approved oral prescription medication for the treatment
of erectile dysfunction (ED) in men. It is available in 2.5 mg,
5 mg, 10 mg, and 20 mg tablets and is taken only when needed.
Levitra helps increase blood flow to the penis and may help men
with ED get and keep an erection satisfactory for sexual activity.
Once a man has completed sexual activity, blood flow to his penis
should decrease and his erection should go away.
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.
