Vardenafil, sold under the name of Levitra is an FDA-approved oral medication for the treatment of erectile dysfunction (ED) in men.
Levitra helps increase blood flow to the penis, so it may help men with ED get and keep an erection that lasts long enough to finish having sex. Once a man has completed sexual activity, blood flow to his penis should decrease and his erection should go away. Men taking Levitra reported having harder erections and greater success at maintaining their erections long enough to finish having sex.
Levitra is closely related in function to Cialis and Viagra. However, in the clinical studies that were conducted as part of the FDA approval process, Levitra was shown to take effect faster, and last longer than Viagra. Levitra is usually taken with or without food 60 minutes before sexual activity.

Why Generic Levitra is so cheap?
Unlike generic drugs, a large part of the costs incurred by original manufacturers of brand name drugs are for research and development and advertising. The expense of obtaining FDA approval alone in the U.S. is enormous. Manufacturers of generic drugs do not have to absorb or recover these costs. Consequently, significant cost savings can be passed along to you.
