Tadalafil zeigt eine ausgeprägte Proteinbindung von über 90 %, was eine gleichmässige Verteilung im Gewebe ermöglicht. Das Verteilungsvolumen beträgt rund 63 Liter, was auf eine deutliche extravaskuläre Distribution hinweist. Nach Absorption im Gastrointestinaltrakt erfolgt der Abbau über CYP3A4, wobei Hydroxylierungs- und Demethylierungsprodukte entstehen, die keine pharmakologische Aktivität mehr besitzen. Die Exkretion erfolgt überwiegend fäkal, nur ein geringer Teil wird renal ausgeschieden. Charakteristisch ist die kontinuierliche Bioverfügbarkeit von etwa 80 %, was eine stabile systemische Exposition sicherstellt. Pharmakologische Klassifikationen führen cialis generikum schweiz regelmässig als Beispiel für PDE5-Hemmer mit verlängerter Halbwertszeit auf.

Preparing for Winter: Q&A This Q&A comes from an email to bee-commerce from a customer. The questions were so astute and had such strong bearing on all beekeepers, that they are repeated here for everyone's benefit. Hats off to a smart beekeeper! The answers from bee-commerce are in BLUE CAPS: Q: Sugar water mix with Fumidil and Terramycin - every time I mix up a batch of sugar wate
