Levitra is the brand name for vardenafil, an oral medication used to treat men who have sexual impotence, also known as erectile dysfunction or ED. It's part of a group of drugs known as phosphodiesterase-5 (PDE5) inhibitors. ... The Food and Drug Administration (FDA) approved Levitra in 2003.
It's part of a group of drugs known as phosphodiesterase-5 (PDE5) inhibitors. PDE5 inhibitors work by preventing an enzyme, PDE5, from working too rapidly in certain areas of the body, including the penis.
Levitra increases venous congestion in that area and helps a man get and keep an erection during sexual intercourse. By itself, Levitra does not cause an erection - there must also be physical stimulation of the penis to achieve an erection.
