Mechanism and action
Cialis Daily: Die PDE5-Hemmung durch Tadalafil verhindert den Abbau von zyklischem GMP in der penilen und vaskulären glatten Muskulatur. Viagra Professional: Sildenafilcitrat hemmt die PDE5, sodass das während der sexuellen Erregung produzierte zyklische GMP im Penisgewebe akkumulieren kann, was die glatte Muskulatur der Penisarterien entspannt und den Bluteinstrom erhöht.
