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.evitra 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.
Since Levitra is a popular medication, there are several generics on the market. Just be sure that the country of origin has a well-regulated pharmaceutical industry. Any drug that contains the same volumes of Vardenafil as Levitra will have the same effect and is therefore a generic Levitra 20 mg.
