Mechanism and action
Ovestin: Estriol in Ovestin bindet an Östrogenrezeptoren mit kürzerer Rezeptorbindung als Estradiol und erzeugt dadurch einen schwachen östrogenen Effekt. 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.
