what is Levitra ?

LEVITRA is the brand name for the generic medicine, Vardenafil, so they are the same thing.

Vardenafil blocks the action of an enzyme known as specific phosphodiesterase type 5,

which enhances nitric oxide release, which increases blood flow into the penis making an erection hard enough, to have sex.

They only work, when you are sexually stimulated, but they have been proven, to help men with all degrees of erectile dysfunction.
