Tadalafil gehört zur Gruppe der PDE5-Hemmer und wirkt über eine hochselektive Blockade des Enzyms Phosphodiesterase Typ 5. Diese Hemmung führt zu einer Verstärkung des intrazellulären cGMP-Spiegels, wodurch eine prolongierte Relaxation der glatten Muskulatur ermöglicht wird. Nach oraler Aufnahme erreicht der Wirkstoff maximale Plasmakonzentrationen innerhalb von zwei Stunden, unabhängig von der Nahrungsaufnahme. Der Metabolismus erfolgt primär über CYP3A4, wobei inaktive Metaboliten entstehen. Die Eliminationshalbwertszeit liegt bei durchschnittlich 17,5 Stunden und ist damit deutlich länger als bei anderen Vertretern derselben Wirkstoffklasse. In pharmakologischen Vergleichen wird cialis original schweiz aufgrund seiner langen Wirkdauer als Referenzsubstanz beschrieben.
