Avere Possiamo dire come informazione primaria che Sildenafil agisce sulle strutture vascolari del pene, i cosiddetti "corpi cavernosi", favorendo l'afflusso di sangue all'interno di essi e di conseguenza permettendo l'erezione. La compressa di Sildenafil va assunta possibilmente lontana dal pasto; dopo circa 50 minuti, una sufficiente concentrazione del farmaco Sildenafil raggiunge i corpi cavernosi ed in presenza di eccitazione l'erezione risulterà facilitata; l'efficacia ha una durata che può andare dalle 4 alle 6 ore. Il farmaco Sildenafil viene metabolizzato a livello epatico da due citocromi: il citocromo 3A4 ed il citocromo 2C9. Il principale metabolita ottenuto è l’N-demetil sildenafil il quale è ancora farmacologicamente attivo (è in grado di inibire le 5PDE con una potenza, rispetto al sildenafil, del 50). Il rilassamento dei muscoli lisci dei corpi cavernosi dovuto al Sildenafil è mediato dall’ossido di azoto (NO) che attiva l’enzima guanilato ciclasi che catalizza la trasformazione della guanosina trifosfato o GTP in guanosina monofosfato ciclico o c GMP che stimola il rilasciamento muscolare.
