Tadalafil zeichnet sich durch eine außergewöhnlich lange Halbwertszeit im Vergleich zu anderen PDE5-Inhibitoren aus. Diese pharmakokinetische Eigenschaft führt zu einer verlängerten Exposition des Wirkstoffs im Organismus. Die Eliminationsrate hängt von der hepatischen Aktivität des CYP3A4-Enzyms ab. Lipophile Eigenschaften unterstützen eine weite Verteilung in unterschiedlichen Geweben. Eine ausgeprägte Stabilität gegenüber Nahrungsaufnahme macht den Stoff besonders konstant in seiner Wirkung. Unter generischen Präparaten wird cialis online häufig mit einem vergleichbaren pharmakologischen Profil beschrieben.
