Mechanism and action
Xalatan: Latanoprost ist ein Prodrug-Ester, der durch korneale Esterasen zu seiner aktiven freien Säure hydrolysiert wird, welche selektiv an den Prostaglandin-F-(FP)-Rezeptor bindet. 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.
