Vardenafil (INN) is a PDE5 inhibitor used for treating erectile dysfunction. Vardenafil's indications and contra-indications are the same as with other PDE5 inhibitors. The difference between the vardenafil molecule and is a nitrogen atom's position and the change of sildenafil's piperazine ring methyl group to an ethyl group. Tadalafil is structurally different from both and vardenafil. Vardenafil's relatively short effective time is comparable to but somewhat longer than sildenafil's.
Beyond its indications for erectile dysfunction, vardenafil may be effective in the treatment of premature ejaculation, where it may significantly increase the time from vaginal penetration to ejaculation.
Vardenafil, as with all PDE5 inhibitors, should not be used by men taking nitrate medications, because combining them with vardenafil might provoke potentially life-threatening hypotension (low blood pressure).
Further, Vardenafil causing lengthening of the QT interval. Therefore it should not be taken by men taking other medications that affect the QT interval (such as amiodarone).

Vardenafil's indications and contra-indications are the same as with other PDE5 inhibitors; it is closely related in function to citrate and tadalafil . The difference between the vardenafil molecule and citrate is a nitrogen atom's position and the change of piperazine ring methyl group to an ethyl group. Tadalafil is structurally different from both and vardenafil. Vardenafil's relatively short effective time is comparable to but somewhat longer than it.
Beyond its indications for erectile dysfunction, vardenafil may be effective in the treatment of premature ejaculation, where it may significantly increase the time from penetration to ejaculation.
