Description:

Vardenfil is an oral drug that is used to treat impotence, the inability to attain or maintain a penile erection. It has a mechanism of action that is similar to sildeafil , and tadlafil (). Penile erection is caused by the engorgement of the peis with blood. This engorgement occurs when the blood vessels delivering blood to the s increase in size and increase the delivery of blood to the pens. At the same time, the blood vessels carrying blood away from the pes decrease in size . stimulation that leads to the engorgement and erection causes the production and release of nitric oxide in the pen.

Vardenfil (INN) is a PDE5 inhibitor used for treating erectile dysfunction. Vardeafil's indications and contra-indications are the same as with other PDE5 inhibitors; it is closely related in function to sildeafil citrate and tadlafil (). The difference between the vardeafil molecule and sildeafil citrate is a nitrogen atom's position and the change of sildeafil's piperazine ring methyl group to an ethyl group. Tadlafil is structurally different from both sildeafil and vardenfil. Vardeafil's relatively short effective time is comparable to but somewhat longer than silenafil's.
