A vardenafil az erektilis dysfunctioban szenvedő férfiak orális kezelésére szolgáló gyógyszer. Természetes körülmények között, azaz szexuális ingerre helyreállítja a zavart erekciós működést a penis vérátáramlásának fokozása révén. A szexuális stimulus nitrogén oxid felszabadulásához vezet. Aktiválja a guanil cikláz enzimet, amely a ciklikus guanozin monofoszfát (c GMP) szintjének emelkedéséhez vezet a corpus cavernosumban. Ez viszont simaizom ellazulást okoz, ami lehetővé teszi a fokozott vérbeáramlást a penisbe. A c GMP szintjét a guanil cikláz révén a szintézis üteme illetve a c GMP lebomlásának mértéke szabja meg a hidrolizáló foszfodieszterázok (PDE) útján. A vardenafil a c GMP-re specifikus 5 típusú foszfodieszteráz hatásos és szelektív gátlója, amely a corpus cavernosumban a legjelentősebb PDE. A vardenafil a PDE5 gátlása révén hatékonyan fokozza az endogén nitrogén oxid hatását a corpus cavernosumban.
