Background

Vardenafil is a selective inhibitor of cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase type 5 (PDE5) and an oral therapy for the treatment of erectile dysfunction. During sexual stimulation, nitric oxide (NO) is released from nerve endings and endothelial cells in the corpus cavernosum, activating the enzyme guanylate cyclase and increasing the synthesis of cGMP in the smooth muscle cells of the corpus cavernosum. PDE5 inhibitors, such as vardenafil, inhibit the degradation of cGMP and allow increased blood flow into the penis, resulting in an erection.. Compared to sildenafil and tadalafil, vardenafil is a more potent inhibitor of PDE5; however, its selectivity for other PDE isoforms is lower than the one detected for tadalafil.

The FDA approved the use of vardenafil for the treatment of erectile dysfunction in 2003. Although other PDE5 inhibitors such as sildenafil and tadalafil have been associated with rare cases of acute liver injury, the use of vardenafil has not been linked to hepatotoxic effects. The use of vardenafil as a monotherapy for the treatment of pulmonary arterial hypertension has also been evaluated.

Indication

Vardenafil is indicated for the treatment of erectile dysfunction.
