Die Struktur von Tadalafil erlaubt eine selektive Bindung an die Bindungsstelle der PDE5 und minimiert gleichzeitig die Interaktion mit PDE6, was visuelle Nebenwirkungen einschränkt. Seine Verteilung im Organismus erfolgt breit, wobei das Verteilungsvolumen etwa 63 Liter beträgt. Über 90 % des Wirkstoffs sind an Plasmaproteine gebunden. Die Wirkung bleibt unabhängig von der Nahrungsaufnahme konstant. Der Abbauweg über CYP3A4 kann durch Hemmer wie Ritonavir oder Ketoconazol verlangsamt werden, was die Plasmakonzentrationen deutlich erhöht. In diesem Kontext wird cialis 20mg preis häufig in Bezug auf pharmakokinetische Wechselwirkungen erwähnt.
