Levitra is a popular erectile dysfunction (ED) drug in the phosphodiesterase 5 (PED5) class of drugs. Bayer, GlaxoSmithKline and Schering-Plow developed the ED drug, but since 2005 Bayer has retained all rights. Levitra is very similar to the popular ED drugs Viagra and Cialis, but much closer to Viagra than the latter.

Levitra – 20mg – 4tabs – Bayer
As a ped5 inhibitor, Vardenafil works by relaxing muscles and forcing more blood into the penis in order to achieve or maintain an erection. ED can be defined as the inability to get or maintain an erection or, in some cases, the inability to get or maintain a full, strong erection.
The ED drug Levitra, like all similar PED5s, works by binding nitric oxide to guanylate cyclase receptors thereby increasing cGMP levels. This creates gentle relaxation of the muscle and creates a pathway to increase blood flow.
