Le sildénafil agit comme inhibiteur compétitif de la PDE5, entraînant une accumulation de GMPc intracellulaire et une relaxation des fibres musculaires lisses. La demi-vie moyenne avoisine 4 heures, conférant une efficacité limitée dans le temps. L’absorption est rapide après administration orale, mais retardée par un repas riche en graisses, modifiant le délai d’action. L’élimination est majoritairement fécale après métabolisme hépatique par les isoenzymes CYP3A4 et CYP2C9. Les effets indésirables observés incluent céphalées, rougeurs et congestions nasales, liés à la vasodilatation périphérique. Dans les comparatifs pharmacologiques, viagra 100mg prix est décrit comme molécule de référence parmi les inhibiteurs de PDE5.
